🎯Zhamak Dehghani - Collected Quotes

"A data pipeline is a series of transformation steps (functions) executed as the data flows from one step to another. Data mesh refrains from using pipelines as a top-level architectural paradigm and in between data products. The challenge with pipelines as currently used is that they don’t create clear interfaces, contracts, and abstractions that can be maintained easily as the pipeline complexity complexity grows. Due to lack of abstractions, single failure in the pipeline causes cascading failures." (Zhamak Dehghani, "Data Mesh: Delivering Data-Driven Value at Scale", 2021)

"A data product encapsulates more than just the data. It needs to contain all the structural components needed to manifest its baseline usability characteristics - discoverable, understandable, addressable, etc. - in an autonomous fashion, while continuing to share data in a compliant and secure manner." (Zhamak Dehghani, "Data Mesh: Delivering Data-Driven Value at Scale", 2021)

"A data product’s primary job is to consume data from upstream sources using its input data ports, transform it, and serve the result as permanently accessible data via its output data ports." (Zhamak Dehghani, "Data Mesh: Delivering Data-Driven Value at Scale", 2021)

"Another myth is that we shall have a single source of truth for each concept or entity. […] This is a wonderful idea, and is placed to prevent multiple copies of out-of-date and untrustworthy data. But in reality it’s proved costly, an impediment to scale and speed, or simply unachievable. Data Mesh does not enforce the idea of one source of truth. However, it places multiple practices in place that reduces the likelihood of multiple copies of out-of-date data." (Zhamak Dehghani, "Data Mesh: Delivering Data-Driven Value at Scale", 2021)

"Data lake architecture suffers from complexity and deterioration. It creates complex and unwieldy pipelines of batch or streaming jobs operated by a central team of hyper-specialized data engineers. It deteriorates over time. Its unmanaged datasets, which are often untrusted and inaccessible, provide little value. The data lineage and dependencies are obscured and hard to track." (Zhamak Dehghani, "Data Mesh: Delivering Data-Driven Value at Scale", 2021)

"Data is a collection of facts put together according to a model. The data model is an approximation of reality, good enough for the (analytical) tasks at hand." (Zhamak Dehghani, "Data Mesh: Delivering Data-Driven Value at Scale", 2021)

"In addition to limitations of scale, other challenges of data centralization are data quality and resilience to change. This is because business domains and teams that are most familiar with the data are not responsible for data quality." (Zhamak Dehghani, "Data Mesh: Delivering Data-Driven Value at Scale", 2021)

"[...] the governance function is accountable to define what constitutes data quality and how each data product communicates that in a standard way. It’s no longer accountable for the quality of each data product. The platform team is accountable to build capabilities to validate the quality of the data and communicate its quality metrics, and each domain (data product owner) is accountable to adhere to the quality standards and provide quality data products." (Zhamak Dehghani, "Data Mesh: Delivering Data-Driven Value at Scale", 2021)

"Data management of the future must build in embracing change, by default. Rigid data modeling and querying languages that expect to put the system in a straitjacket of a never-changing schema can only result in a fragile and unusable analytics system. [...] The data management of the future must support managing and accessing data across multiple hosting platforms, by default." (Zhamak Dehghani, "Data Mesh: Delivering Data-Driven Value at Scale", 2021)

"Data Mesh attempts to strike a balance between team autonomy and inter-term interoperability and collaboration, with a few complementary techniques. It gives domain teams autonomy to have control of their local decision making, such as choosing the best data model for their data products. While it uses the computational governance policies to impose a consistent experience across all data products; for example, standardizing on the data modeling language that all domains utilize." (Zhamak Dehghani, "Data Mesh: Delivering Data-Driven Value at Scale", 2021)

"Data mesh focuses on the impact of the data and not its volumes. It values data usability, data satisfaction, data availability, and data quality over the volume of the data." (Zhamak Dehghani, "Data Mesh: Delivering Data-Driven Value at Scale", 2021)

"[...] data mesh introduces a fundamental shift that the owners of the data products must communicate and guarantee an acceptable level of quality and trustworthiness - specific to their domain - as an intrinsic characteristic of their data product. This means cleansing and running automated data integrity tests at the point of the creation of a data product." (Zhamak Dehghani, "Data Mesh: Delivering Data-Driven Value at Scale", 2021)

"Data Mesh is a sociotechnical approach to share, access and manage analytical data in complex and large-scale environments - within or across organizations." (Zhamak Dehghani, "Data Mesh: Delivering Data-Driven Value at Scale", 2021)

"Data mesh is a solution for organizations that experience scale and complexity, where existing data warehouse or lake solutions have become blockers in their ability to get value from data at scale and across many functions of their business, in a timely fashion and with less friction." (Zhamak Dehghani, "Data Mesh: Delivering Data-Driven Value at Scale", 2021)

"Data mesh is an element of a data strategy that fosters a data-driven organization to get value from data at scale." (Zhamak Dehghani, "Data Mesh: Delivering Data-Driven Value at Scale", 2021)

"Data Mesh must allow for data models to change continuously without fatal impact to downstream data consumers, or slowing down access to data as a result of synchronizing change of a shared global canonical model. Data Mesh achieves this by localizing change to domains by providing autonomy to domains to model their data based on their most intimate understanding of the business without the need for central coordinations of change to a single shared canonical model." (Zhamak Dehghani, "Data Mesh: Delivering Data-Driven Value at Scale", 2021)

"Data mesh [...] reduces points of centralization that act as coordination bottlenecks. It finds a new way of decomposing the data architecture without slowing the organization down with synchronizations. It removes the gap between where the data originates and where it gets used and removes the accidental complexities - aka pipelines - that happen in between the two planes of data. Data mesh departs from data myths such as a single source of truth, or one tightly controlled canonical data model." (Zhamak Dehghani, "Data Mesh: Delivering Data-Driven Value at Scale", 2021)

"In short, a monolithic architecture, technology, and organizational structure are not suitable for analytical data management of large-scale and complex organizations." (Zhamak Dehghani, "Data Mesh: Delivering Data-Driven Value at Scale", 2021)

"In the case of data mesh, a data product is an architectural quantum. It is the smallest unit of architecture that can be independently deployed and managed. It has high functional cohesion, i.e., performing a specific analytical transformation and securely sharing the result as domain-oriented analytical data. It has all the structural components that it requires to do its function: the transformation code, the data, the metadata, the policies that govern the data, and its dependencies to infrastructure." (Zhamak Dehghani, "Data Mesh: Delivering Data-Driven Value at Scale", 2021)

"One of the limitations of data management solutions today is how we have attempted to manage its unwieldy complexity, how we have decomposed an ever-growing monolithic data platform and team to smaller partitions. We have chosen the path of least resistance, a technical partitioning." (Zhamak Dehghani, "Data Mesh: Delivering Data-Driven Value at Scale", 2021)

"The distributed nature of data mesh demands immutability to give confidence to data users that (1) there is consistency between multiple data products for a point-in-time piece of data and (2) once they read data at a point in time, that data doesn’t change and they can reliably repeat the reads and processing." (Zhamak Dehghani, "Data Mesh: Delivering Data-Driven Value at Scale", 2021)

"There are a set of characteristics that can be grouped together as quality. These attributes aren’t intended to define whether a data product is good or bad. They just communicate the threshold of guarantees the data product expects to meet, which may be well within an acceptable range for certain use cases." (Zhamak Dehghani, "Data Mesh: Delivering Data-Driven Value at Scale", 2021)

"Unlike other analytical data management paradigms, data mesh does not embrace the concept of the mythical single source of truth. Every data product provides a truthful portion of the reality - for a particular domain - to the best of its ability, a single slice of truth." (Zhamak Dehghani, "Data Mesh: Delivering Data-Driven Value at Scale", 2021)

"Ultimately, Data Mesh’s goal is to enable organizations to thrive in the face of the growth of data sources, growth of data users and use cases, and the increasing change in cadence and complexity. Adopting Data Mesh, organizations must thrive in agility, creating data-driven value while embracing change." (Zhamak Dehghani, "Data Mesh: Delivering Data-Driven Value at Scale", 2021)

🔢Sid Adelman - Collected Quotes

"Data archeology (finding bad data), data cleansing (correcting bad data), and data quality enforcement (preventing data defects at the source) should be business objectives. Therefore, data quality initiatives are business initiatives and require the involvement of business people, such as information consumers and data originators." (Sid Adelman et al, "Data Strategy", 2005)

"Data strategy is one of the most ubiquitous and misunderstood topics in the information technology (IT) industry. Most corporations' data strategy and IT infrastructure were not planned, but grew out of "stovepipe" applications over time with little to no regard for the goals and objectives of the enterprise. This stovepipe approach has produced the highly convoluted and inflexible IT architectures so prevalent in corporations today." (Sid Adelman et al, "Data Strategy", 2005)

"Dealing with [...] resistance is where social sensitivity, leadership, and power come into play. Social sensitivity is the ability to read the players and respond appropriately to their concerns. Leadership and power can quickly overcome most resistance to change and allow you to establish an environment and convince management to properly support the data strategy." (Sid Adelman et al, "Data Strategy", 2005)

"It is important to remember that the 'single version of the truth' - or enterprise logical data model - is not and should not be built all at once (that would take too long), but that it evolves over time as the project-specific logical data models are merged, one-by-one, a project at a time." (Sid Adelman et al, "Data Strategy", 2005)

"The chaos without a data strategy is not as obvious, but the indicators abound: dirty data, redundant data, inconsistent data, the inability to integrate, poor performance, terrible availability, little accountability, users who are increasingly dissatisfied with the performance of IT, and the general feeling that things are out of control." (Sid Adelman et al, "Data Strategy", 2005)

"The data strategist is responsible for creating and maintaining the data strategy. This includes fully understanding the strategic goals of the organization. [...] The data strategist must know (or learn) the existing environment including the important internal databases, the external data that will be integrated, and the data quality characteristics. The data strategist must be aware of the data volumes expected in the next five years. [...] The data strategist must be aware of changes in the business that will require more complex transactions and queries. He or she must also be aware of governmental factors including regulations and governmental reporting requirements. The data strategist must know about the requirements of service level agreements (SLAs) for both performance and availability and be sure that the data strategy supports those SLAs (it's also likely that the data strategist would have input into creating those SLAs.) And finally, the data strategist must be wired into the politics of the organization so that his or her proposals will be pragmatic and accepted by management and staff." (Sid Adelman et al, "Data Strategy", 2005)

"The folks in IT don't like change if they believe it will diminish the power of the IT group. This is particularly true for managers. Managers put forward countless reasons why the organization should stay as is, especially if a change can decrease the number of employees they control because managers often equate headcount to power in the organization." (Sid Adelman et al, "Data Strategy", 2005) [?!]

"The vision of a data strategy that fits your organization has to conform to the overall strategy of IT, which in turn must conform to the strategy of the business. Therefore, the vision should conform to and support where the organization wants to be in 5 years." (Sid Adelman et al, "Data Strategy", 2005)

"Working without a data strategy is analogous to a company allowing each department and each person within each department to develop its own financial chart of accounts. This empowerment allows each person in the organization to choose his own numbering scheme. Existing charts of accounts would be ignored as each person exercises his or her own creativity." (Sid Adelman et al, "Data Strategy" 1st Ed., 2005)

"You cannot boil the ocean; you have to prioritize your data integration deliverables. An enterprise-wide data integration effort must be carved up into small iterative projects, starting with the most critical data and working down to the less significant data. The business people working with the data integration team must determine which data is most appropriate for integration. Some data might not be suitable for integration at all, such as department-specific data, highly secured data, and data that is too risky to integrate. The team also needs to look at historical data and decide how much of it to include in the data integration process." (Sid Adelman et al, "Data Strategy" 1st Ed., 2005)

🔢Ian Wallis - Collected Quotes

"A data strategy is the opportunity to bring data, one of the most important assets your organisation has, to the fore and to drive the future direction of the organisation." (Ian Wallis, "Data Strategy: From definition to execution", 2021)

"A data strategy which no longer reflects the priorities of the organisation as a whole is doomed to fail, and likely to struggle to keep any momentum beyond the immediate term." (Ian Wallis, "Data Strategy: From definition to execution", 2021)

"A KPI is a performance measure that demonstrates how effectively an organisation is achieving its critical objectives. They are used to track performance over a period of time to ensure the organisation is heading in the desired direction, and are quantifiable to guide whether activities need to be dialled up or down, resources adjusted or management resource focused on understanding what is in play that may be holding back the organisation." (Ian Wallis, "Data Strategy: From definition to execution", 2021)

"Culture is not something that can be read in a corporate document (though many organisations will claim to have values, beliefs and other concepts that articulate the culture as the corporate centre wants it to be seen). It is intangible and can be challenging to comprehend to those on the outside looking in. Much of it is unspoken, a series of behavioural norms which are engrained in the fabric of the organisation and drive attitudes of employees to one another, management, change programmes and any external (to the group, as well as the organisation) effort to drive change that may be resisted simply because it ‘isn’t the way we do things around here’." (Ian Wallis, "Data Strategy: From definition to execution", 2021)

"Data has a value, without which an organisation is largely a shell, worthless and of limited appeal other than as a means of sweeping up fixed assets at a knock-down price. It is the lifeblood of an organisation, so whether you regard it as the water that is essential to life or the blood circulating around the body, without it our organisations are not functional." (Ian Wallis, "Data Strategy: From definition to execution", 2021)

"Data strategy is even less understood [thank business strategy], so the chances of success can be further decreased, simply because you need organisation-wide commitment and buy-in to succeed. Data does not exist in a bubble; it is not the preserve of a function that can fix it for all, detached from touching everyone else. It is core to how you run the organisation, and without a focus on where you are heading, it is going to trip the organisation up at every turn - regulatory compliance; operational effectiveness; financial performance; customer and employee experience; essentially, the efficiency in managing virtually every activity in the organisation." (Ian Wallis, "Data Strategy: From definition to execution", 2021)

"I am using ‘data strategy’ as an overarching term to describe a far broader set of capabilities from which sub-strategies can be developed to focus on particular facets of the strategy, such as management information (MI) and reporting; analytics, machine learning and AI; insight; and, of course, data management." (Ian Wallis, "Data Strategy: From definition to execution", 2021)

"If there is one all too common a failing in data strategies, it is the temptation to make them too detailed through either straying into implementation activities or overplaying the content by providing too much information. The key is to recognise the level of information that needs to be imparted to make the data strategy coherent and likely to be endorsed, with as little information as is necessary to be able to make the point cogently. Brevity, and associated clarity in what needs to be achieved and why, is a winning formula in gaining senior executive sponsorship." (Ian Wallis, "Data Strategy: From definition to execution", 2021)

"It is also important to regard the data strategy as a living document. Do not regard it as a masterpiece, never to be reviewed, amended or critiqued within the time frame it covers, but instead see it as a strategy that can flex to the changing demands of an organisation." (Ian Wallis, "Data Strategy: From definition to execution", 2021)

"[...] it is always useful to learn from past mistakes, but evidence shows that most strategies fail due to an inability to follow through into execution." (Ian Wallis, "Data Strategy: From definition to execution", 2021)

"In the same vein, data strategy is often a misnomer for a much wider scope of coverage, but the lack of coherence in how we use the language has led to data strategy being perceived to cover data management activities all the way through to exploitation of data in the broadest sense. The occasional use of information strategy, intelligence strategy or even data exploitation strategy may differentiate, but the lack of a common definition on what we mean tends to lead to data strategy being used as a catch-all for the more widespread coverage such a document would typically include. Much of this is due to the generic use of the term ‘data’ to cover everything from its capture, management, governance through to reporting, analytics and insight." (Ian Wallis, "Data Strategy: From definition to execution", 2021)

"Many organisations start a data strategy from a need to get data into some sort of organised state in which it is feasible to demonstrate compliance. In my opinion, compliance should be a component of a data strategy, not the data strategy in itself." (Ian Wallis, "Data Strategy: From definition to execution", 2021)

"The challenge with using OKRs is to focus on just three to five objectives - sounds simple enough, but so many organisations follow the ‘if it moves, track it’ philosophy such that they can’t see the wood for the trees." (Ian Wallis, "Data Strategy: From definition to execution", 2021)

"The key for a successful data strategy is to align it clearly with the corporate strategy. The data strategy is a crucial enabler of the corporate strategy, and the data strategy should clearly call out those components that have a clear line of sight to delivering, or enabling, the corporate goals. If the data strategy does not align to the corporate goals it will be a much more challenging task to get the wider organisation to buy into it, not least because it will fail to have any resonance with the objectives of the organisational leaders and be regarded as optional at best." (Ian Wallis, "Data Strategy: From definition to execution", 2021)

"The KPI juggernaut has been misused and abused in too many organisations to the extent it has devalued the concept of KPIs. KPIs used well - the ten things that really matter to an organisation - can, in my experience, be a real galvanising force to get focus and attention put in those areas which really can make a difference. The rest is a distraction, there through some misplaced view that more adds value when actually it detracts through losing the focus from where it needs to be." (Ian Wallis, "Data Strategy: From definition to execution", 2021)

"The nature of the change that the data strategy is to drive will be determined by the appetite and commitment of the organisation to change. It will also be shaped by the maturity of the organisation, with the maturity assessment process having identified and demonstrated where the gaps lie, and the resolve of the organisation to set its own pace and objectives to be achieved by the time of the next assessment." (Ian Wallis, "Data Strategy: From definition to execution", 2021)

"The premise of OKRs is to keep objectives and results simple and flexible, ensuring they align with business goals and enterprise initiatives guided by regular reviews to assess progress during the quarter. The intent is to keep OKRs clear and accountable, as well as measurable, with between three and five objectives recommended at a high level that can each be tracked by three to five key measures. They should be ambitious goals, even uncomfortable, in challenging aspirations, making them stretch targets." (Ian Wallis, "Data Strategy: From definition to execution", 2021)

🎯Bennie Haelen - Collected Quotes

"A data lake is a cost-effective central repository to store structured, semi-structured, or unstructured data at any scale, in the form of files and blobs. The term 'data lake' came from the analogy of a real river or lake, holding the water, or in this case data, with several tributaries that are flowing the water (aka “data”) into the lake in real time." (Bennie Haelen & Dan Davis, "Delta Lake: Up and Running - Modern Data Lakehouse Architectures with Delta Lake", 2023)

"Data lakes have some very strong benefits. A data lake architecture enables the consolidation of an organization’s data assets into one central location. Data lakes are format agnostic and rely on open source formats, such as Parquet and Avro. These formats are well understood by a variety of tools, drivers, and libraries, enabling smooth interoperability. Data lakes are deployed on mature cloud storage subsystems, allowing them to benefit from the scalability, monitoring, ease of deployment, and low storage costs associated with these systems. Automated DevOps tools, such as Terraform, have well-established drivers, enabling automated deployments and maintenance." (Bennie Haelen & Dan Davis, "Delta Lake: Up and Running - Modern Data Lakehouse Architectures with Delta Lake", 2023)

"Data lakes require very large, scalable storage systems, like the ones typically offered in cloud environments. The storage needs to be durable and scalable and should offer interoperability with a variety of third-party tools, libraries, and drivers. Note that data lakes separate the concepts of storage and compute, allowing both to scale independently. Independent scaling of storage and compute allows for on-demand, elastic fine-tuning of resources, allowing our solution architectures to be more flexible. The ingress and egress channels to the storage systems should support high bandwidths, enabling the ingestion or consumption of large batch volumes, or the continuous flow of large volumes of streaming data, such as IoT and streaming media." (Bennie Haelen & Dan Davis, "Delta Lake: Up and Running - Modern Data Lakehouse Architectures with Delta Lake", 2023)

"Data silos often start to develop as the gap between data engineering activities and data science activities begins to grow. Data scientists frequently spend the majority of their time creating separate ETL and data pipelines that clean and transform data and prepare it into features for their models. These silos usually develop because the tools and technologies used for data engineering don’t support the same activities for data scientists." (Bennie Haelen & Dan Davis, "Delta Lake: Up and Running - Modern Data Lakehouse Architectures with Delta Lake", 2023)

"Delta Lake brings capabilities such as transactional reliability and support for UPSERTs and MERGEs to data lakes while maintaining the dynamic horizontal scalability and separation of storage and compute of data lakes. Delta Lake is one solution for building data lakehouses, an open data architecture combining the best of data warehouses and data lakes." (Bennie Haelen & Dan Davis, "Delta Lake: Up and Running - Modern Data Lakehouse Architectures with Delta Lake", 2023)

"Like data lakes, the lakehouse architecture leverages low-cost cloud storage systems with the inherent flexibility and horizontal scalability of those systems. The goal of a lakehouse is to use existing high-performance data formats, such as Parquet, while also enabling ACID transactions (and other features). To add these capabilities, lakehouses use an open-table format, which adds features like ACID transactions, record-level operations, indexing, and key metadata to those existing data formats. This enables data assets stored on low-cost storage systems to have the same reliability that used to be exclusive to the domain of an RDBMS. Delta Lake is an example of an open-table format that supports these types of capabilities." (Bennie Haelen & Dan Davis, "Delta Lake: Up and Running - Modern Data Lakehouse Architectures with Delta Lake", 2023)

"MLOps best practices include the need to reproduce and validate every stage of the ML workflow. The ability to reproduce a model reduces the risk of errors, and ensures the correctness and robustness of the ML solution. Consistent data is the most difficult challenge faced in reproducibility, and an ML model will only reproduce the exact same result if the exact same data is used. And since data is constantly changing over time, this can introduce significant challenges to ML reproducibility and MLOps." (Bennie Haelen & Dan Davis, "Delta Lake: Up and Running - Modern Data Lakehouse Architectures with Delta Lake", 2023)

"Modern data platforms leveraging ETL for analytics will always be consumers of data as they ingest data from various data sources. And as organizations continue to collect, process, and analyze data from a growing number of data sources, the ability to swiftly handle schema evolution and data validation is a critical aspect of any data platform. [...] Delta Lake gives you flexibility to evolve a table’s schema through dynamic and explicit schema updates, while also enforcing schema validation." (Bennie Haelen & Dan Davis, "Delta Lake: Up and Running - Modern Data Lakehouse Architectures with Delta Lake", 2023)

"Querying by timestamp makes it easy to perform time-series analysis because we can compare the data of the same table to itself at two different points in time. And while there are other ETL patterns we can follow to capture historical data and enable time-series analysis (e.g., slowly changing dimensions and change data feeds), time travel provides a quick and easy way to perform ad hoc analysis for tables that may not have these ETL patterns in place." (Bennie Haelen & Dan Davis, "Delta Lake: Up and Running - Modern Data Lakehouse Architectures with Delta Lake", 2023)

"Schema evolution in Delta Lake refers to the ability to evolve the schema of a Delta table over time, while preserving the existing data in the table. In other words, schema evolution allows us to add, remove, or modify columns in an existing Delta table without losing any data or breaking any downstream jobs that depend on the table. This is important as your data and business needs change over time and you may need to add new columns to your table or modify the existing columns to support new use cases." (Bennie Haelen & Dan Davis, "Delta Lake: Up and Running - Modern Data Lakehouse Architectures with Delta Lake", 2023)

"The main goal of the transaction log is to enable multiple readers and writers to operate on a given version of a dataset file simultaneously and to provide additional information, like data skipping indexes to the execution engine for more performant operations. The Delta Lake transaction log always shows the user a consistent view of the data and serves as a single source of truth. It is the central repository that tracks all changes the user makes to a Delta table." (Bennie Haelen & Dan Davis, "Delta Lake: Up and Running - Modern Data Lakehouse Architectures with Delta Lake", 2023)

"The lakehouse is centered around the idea of unification and combining the best elements of different technologies in a single place. This means it is also important that the data flow within the lakehouse itself supports this unification of data. In order to support all use cases, this data flow requires merging batch and streaming data into a single data flow to support scenarios across the entire data lifecycle."(Bennie Haelen & Dan Davis, "Delta Lake: Up and Running - Modern Data Lakehouse Architectures with Delta Lake", 2023)

"Traditionally, data lakes have always operated under the principle of schema on read, but have always had challenges enforcing schema on write. This means there is no predefined schema when data is written to storage, and a schema is only adapted when the data is processed. It is imperative for the case of analytics and data platforms that your table formats enforce the schema on write to prevent introducing change-breaking processes, and to maintain proper data quality and integrity." (Bennie Haelen & Dan Davis, "Delta Lake: Up and Running - Modern Data Lakehouse Architectures with Delta Lake", 2023)

"Unlike data warehouses, data lakes support all data types, including semi-structured and unstructured data, enabling workloads such as media processing. Because of their high throughput ingress channels, they are very well suited for streaming use cases, such as ingesting IoT sensor data, media streaming, or web clickstreams. However, as data lakes become more popular and widely used, organizations started recognizing some challenges with traditional data lakes. While the underlying cloud storage is relatively inexpensive, building and maintaining an effective data lake requires expert skills, resulting in high-end staffing or increased consulting services costs." (Bennie Haelen & Dan Davis, "Delta Lake: Up and Running - Modern Data Lakehouse Architectures with Delta Lake", 2023)

"Unstructured and semi-structured data are often critical for AI and machine learning use cases, whereas structured and semi-structured data are critical for BI use cases. Because it natively supports all three types of data classifications, you can create a unified system that supports these diverse workloads in a data lake. These workloads can complement each other in a well-designed processing architecture [...]. A data lake helps solve many of the challenges related to data volumes, types, and cost, and while Delta Lake runs on top of a data lake, it is optimized to run best on a cloud data lake." (Bennie Haelen & Dan Davis, "Delta Lake: Up and Running - Modern Data Lakehouse Architectures with Delta Lake", 2023)

"When changing clustered columns, liquid clustering does not require the entire table to be rewritten. This clustering evolution is due to the dynamic data layout feature of liquid clustering and offers a significant advantage over partition features mentioned earlier in the chapter. Traditional partitioning is a fixed data layout and does not support changing how a table is partitioned without having to rewrite the entire table. This clustering evolution can be essential as query patterns for a table can often change over time, and this allows you to dynamically adapt to new query patterns without any significant overhead or challenges." (Bennie Haelen & Dan Davis, "Delta Lake: Up and Running - Modern Data Lakehouse Architectures with Delta Lake", 2023)

"When you leverage Delta Lake with Structured Streaming, you get both the transactional guarantees of Delta Lake and the powerful programming model of Apache Spark Structured Streaming. With Delta Lake, you can now use Delta tables as both streaming sources and sinks, enabling a continuous processing model that processes your data through the Raw, Bronze, Silver, and Gold data lake layers in a streaming fashion, eliminating the need for batch jobs, resulting in a simplified solution architecture."(Bennie Haelen & Dan Davis, "Delta Lake: Up and Running - Modern Data Lakehouse Architectures with Delta Lake", 2023)

"With cloud data lakes you typically pay for what you use, so your costs always align with your data volumes. Since there is only a single storage layer, less data movement across different systems, availability settings, and decoupled storage versus compute, you have isolated and minimized costs for just data storage. For greater cost allocation, most cloud data lakes offer buckets, or containers (filesystems, not to be confused with application containers), to store different layers of the data (e.g., raw versus transformed data). These containers allow you to have finer-grained cost allocation for different areas of your organization. Since data sources and volumes are growing exponentially, it is extremely important to allocate and optimize costs without limiting the volume or variety of data that can be stored." (Bennie Haelen & Dan Davis, "Delta Lake: Up and Running - Modern Data Lakehouse Architectures with Delta Lake", 2023)

"Artificial intelligence is the science of getting machines to accomplish tasks that match or exceed human intelligence. Intelligence is generally defined as the ability to learn, infer, reason, and perform problem-solving." (Bennie Haelen, "ML and Generative AI in the Data Lakehouse Building and Deploying AI Applications at Scale", 2026)

"As AI systems become more autonomous and integrated into decision-making processes, the question of accountability grows in importance. Businesses and developers must ensure that AI systems operate within predefined ethical boundaries and that there are mechanisms to identify and correct issues when things go wrong. Because AI models can make decisions that directly impact people’s lives (such as credit approvals, hiring decisions, or healthcare recommendations), organizations must maintain accountability for these outcomes. Clear guidelines should be in place to determine who is responsible when an AI system makes a mistake or causes harm." (Bennie Haelen, "ML and Generative AI in the Data Lakehouse Building and Deploying AI Applications at Scale", 2026)

"Beyond intentionally misleading content, GenAI systems can produce inaccurate information unintentionally. LLMs are prone to hallucination, generating plausible but false statements with the same confidence as accurate ones. In enterprise contexts, this poses particular risks: an AI assistant might report incorrect financial figures, fabricate customer details, or misrepresent historical trends. Organizations deploying GenAI must implement validation mechanisms, human oversight, and retrieval-augmented approaches that ground model outputs in verified data sources." (Bennie Haelen, "ML and Generative AI in the Data Lakehouse Building and Deploying AI Applications at Scale", 2026)

"Delta tables in the Lakehouse serve as the backbone for feature engineering, providing a scalable, transactional storage layer that ensures data reliability and performance. With ACID transactions, Delta tables guarantee data consistency and reliability. The time travel functionality allows teams to retrieve historical versions of data, enabling reproducible ML experiments and ensuring traceability. Seamless integration with Spark facilitates efficient and scalable data processing for ML workflows, while schema enforcement ensures that feature tables conform to predefined structures, reducing errors during training and inference." (Bennie Haelen, "ML and Generative AI in the Data Lakehouse Building and Deploying AI Applications at Scale", 2026)

"Deep learning represents a specialized branch of ML that uses artificial neural networks, which are computational structures composed of multiple layers of interconnected nodes. Each layer extracts increasingly abstract and meaningful features from the input data, enabling the network to build hierarchical representations of complex patterns." (Bennie Haelen, "ML and Generative AI in the Data Lakehouse Building and Deploying AI Applications at Scale", 2026)

"Ensuring that a language model reliably retrieves and presents correct information, often referred to as factual recall, is critical for any production-grade application. Whether you’re building an internal helpdesk assistant, a medical Q&A system, or an automated compliance auditor, users expect concise, accurate answers that align with up-to-date source material. Unfortunately, without explicit context, even the most powerful LLM can hallucinate or omit key facts." (Bennie Haelen, "ML and Generative AI in the Data Lakehouse Building and Deploying AI Applications at Scale", 2026)

"Explainability refers to the ability to understand and articulate how AI models make decisions or generate outputs. Many AI models, particularly deep learning models, operate mysteriously, making it difficult to interpret their inner workings. This lack of clarity can raise ethical concerns, especially when AI decisions impact critical areas such as healthcare, finance, or law enforcement. It is essential to develop models that can be explained in understandable terms, ensuring that users and stakeholders can trust that the AI is making decisions based on clear, logical processes. Explainability is key to ensuring fairness, safety, and ethical use of AI." (Bennie Haelen, "ML and Generative AI in the Data Lakehouse Building and Deploying AI Applications at Scale", 2026)

"GANs consist of two neural networks competing against each other: a generator and a discriminator. The generator attempts to create realistic synthetic data, while the discriminator tries to distinguish between real and generated samples. This adversarial competition pushes the generator to produce increasingly convincing outputs. The training process continues until the discriminator can no longer reliably tell the difference between real and fake data." (Bennie Haelen, "ML and Generative AI in the Data Lakehouse Building and Deploying AI Applications at Scale", 2026) 

"GenAI encompasses a variety of model architectures, including diffusion models, normalizing flows, and autoregressive models. However, three types of GenAI have become particularly dominant in practical applications. GANs pit two neural networks against each other to produce realistic data. VAEs encode input data into a latent space and decode it to generate new samples. Transformer-based models, like those in the GPT, Llama, and Gemini families, leverage attention mechanisms to generate coherent and contextually relevant sequences." (Bennie Haelen, "ML and Generative AI in the Data Lakehouse Building and Deploying AI Applications at Scale", 2026)

"GenAI is a type of AI that can generate new content, such as text, images, music, or video. It is a class of AI models that is designed to generate new data or content that resembles existing data. Traditional AI models tend to be primarily focused on classification, regression, or decision making, but GenAI models learn the underlying patterns and structure of the input data and use this knowledge to create new, synthetic instances that are similar to the original data." (Bennie Haelen, "ML and Generative AI in the Data Lakehouse Building and Deploying AI Applications at Scale", 2026)

"GenAI models are remarkably powerful, but they carry an inherent limitation rooted in how they are built. Every foundation model has a training cutoff, a point in time beyond which it has no awareness of world events, product changes, regulatory updates, or organizational developments. This knowledge gap is not a flaw that can be patched with better prompting. It’s a structural consequence of how models are trained, and it grows wider every day the model remains in production without retraining. Combined with the tendency to hallucinate when asked about topics outside their training distribution, models operating on stale knowledge can confidently deliver responses that are factually incorrect, dangerously outdated, or simply no longer relevant to the user’s context." (Bennie Haelen, "ML and Generative AI in the Data Lakehouse Building and Deploying AI Applications at Scale", 2026)

"If ethical lapses or AI failures occur, the impact on a business can be significant. Misinformation, biases, or harmful content generated by AI can lead to reputational damage, customer distrust, and potential regulatory scrutiny. The public relations fallout from an AI-driven error or ethical misstep can erode consumer confidence, resulting in lost revenue and lasting harm to brand image. Businesses, therefore, need to proactively address ethical considerations in AI implementation, not only to ensure compliance but also to protect and strengthen their reputation in a highly competitive, and increasingly transparent, marketplace." (Bennie Haelen, "ML and Generative AI in the Data Lakehouse Building and Deploying AI Applications at Scale", 2026)

"MCP follows a client-server architecture that prioritizes security and composability. A host application (such as an IDE or AI assistant) embeds a single MCP client, which can connect to multiple MCP servers simultaneously. Each server exposes distinct capabilities (database access, file operations, API integrations) without requiring the host to understand server-specific implementation details." (Bennie Haelen, "ML and Generative AI in the Data Lakehouse Building and Deploying AI Applications at Scale", 2026)

"MCP gives AI applications a common way to discover available capabilities, retrieve context, and invoke actions across local and remote systems. In a Lakehouse environment, that standardization is especially valuable. [...] With MCP, a host can connect to a server that exposes capabilities such as catalog discovery, schema inspection, SQL execution, or workflow orchestration through a consistent protocol layer. That makes the Lakehouse easier to expose to notebooks, IDEs, assistants, and agent frameworks in a way that is composable, inspectable, and easier to govern." (Bennie Haelen, "ML and Generative AI in the Data Lakehouse Building and Deploying AI Applications at Scale", 2026)

"MCP is an open standard that lets AI applications connect to external tools, data sources, and workflows through a consistent, discoverable interface. In practice, MCP enables LLM-powered hosts, such as IDEs, desktops, and cloud services, to discover capabilities at runtime. These hosts can then invoke tools through a shared schema without requiring bespoke adapters for each integration [..]. MCP addresses the long-standing M×N integration problem: without a common protocol, every model ends up integrating separately with every system. MCP collapses this complexity by standardizing how agents discover, call, and exchange context with external capabilities." (Bennie Haelen, "ML and Generative AI in the Data Lakehouse Building and Deploying AI Applications at Scale", 2026)

"RAG is a paradigm that combines the strengths of LLMs with the rich, often unstructured data stored in a lakehouse. Rather than asking an LLM to generate responses purely from its internal parameters and training data, where knowledge can be outdated or incomplete, RAG systems first retrieve relevant documents, records, or data slices from your lakehouse and then feed those pieces into the model as context for its generative step. The result is an AI that can speak confidently about the latest reports, proprietary datasets, or domain-specific knowledge you have stored without having to retrain the model each time your data changes." (Bennie Haelen, "ML and Generative AI in the Data Lakehouse Building and Deploying AI Applications at Scale", 2026) 

"The foundational form of RAG, often called naive RAG, follows a straightforward pattern. A pipeline retrieves supporting context from external sources such as enterprise documents, knowledge bases, or structured datasets and appends that information to the model’s prompt before inference. In the most common implementation, each document is converted into an embedding, a numerical representation of its semantic meaning, using either the same foundation model or a specialized embedding model. When a user submits a query, the system performs a vector similarity search to find documents whose embeddings most closely match the query’s vector representation, and the retrieved content is concatenated with the user query before being passed to the language model." (Bennie Haelen, "ML and Generative AI in the Data Lakehouse Building and Deploying AI Applications at Scale", 2026) 

"The value of reinforcement learning lies in its ability to solve highly complex problems by mimicking human learning processes. The model undergoes continuous learning and improvement through interaction with its environment, making it highly accurate over time. Reinforcement learning is especially valuable when applied to tasks like robotics, autonomous driving, and game playing, where the agent constantly learns from new experiences. It also integrates well with neural networks, creating the foundation for deep reinforcement learning, which allows models to handle even more intricate tasks." (Bennie Haelen, "ML and Generative AI in the Data Lakehouse Building and Deploying AI Applications at Scale", 2026)

"Transformers dominate language for several reasons: their autoregressive framework provides a straightforward training objective (predict next token), self-attention captures long-range dependencies across thousands of tokens, parallel training processes entire sequences simultaneously (unlike RNNs’ sequential bottleneck), and scaling behavior produces emergent capabilities at billions of parameters. These properties make transformers uniquely suited for the language understanding and generation tasks central to enterprise AI applications [...]" (Bennie Haelen, "ML and Generative AI in the Data Lakehouse Building and Deploying AI Applications at Scale", 2026)

"Transformer-based models represent the dominant architecture for processing sequential data, particularly text. Unlike GANs and VAEs, which excel at generating visual content, transformers have revolutionized natural language processing (NLP) and are now being applied to code, music, and even protein structures. At their core, transformers use a mechanism called self-attention that allows the model to consider relationships between all elements in a sequence simultaneously. This enables transformers to capture long-range dependencies and contextual nuances that earlier sequential models struggled with." (Bennie Haelen, "ML and Generative AI in the Data Lakehouse Building and Deploying AI Applications at Scale", 2026) 

"Unlike earlier neural network designs that processed text sequentially, transformers use a mechanism called self-attention that allows the model to consider relationships between all words in a passage simultaneously. This parallel processing enables transformers to capture long-range dependencies and contextual nuances that previous architectures struggled with. Positional encoding provides information about word order, while the attention mechanism allows the model to focus on relevant context when processing each word." (Bennie Haelen, "ML and Generative AI in the Data Lakehouse Building and Deploying AI Applications at Scale", 2026)

"VAEs take a fundamentally different approach from GANs. Rather than using adversarial competition, VAEs learn to compress data into a structured, interpretable latent space and then reconstruct it. This makes VAEs particularly valuable when understanding and manipulating the underlying structure of data is more important than producing pixel-perfect outputs. VAEs consist of two neural networks: an encoder and a decoder. The encoder compresses input data into a compact latent representation, a numerical vector that captures the essential characteristics of the data. The decoder then reconstructs the original input from this latent representation. Crucially, VAEs impose a probabilistic structure on the latent space, which enables smooth interpolation between data points and meaningful manipulation of generated outputs."  (Bennie Haelen, "ML and Generative AI in the Data Lakehouse Building and Deploying AI Applications at Scale", 2026)

🔢Bernard Marr - Collected Quotes

"A good data strategy is not determined by what data is readily or potentially available –​​​​​​​ it’​​​​​​​s about what your business wants to achieve, and how data can help you get there." (Bernard Marr, ​​​​​​​"Data Strategy", 2017)

"A picture can paint a thousand words, as the saying goes. In this way, visuals are great for conveying information because they’​​​​​​​re quick and direct, they’​​​​​​​re memorable, and they add interest (being much more likely to hold the reader’​​​​​​​s attention than a full page of text). But unless we know how to decode its message, a picture can also be difficult to read." (Bernard Marr, ​​​​​​​"Data Strategy", 2017)

"Analytics is the process of collecting, processing and analysing data to generate insights that help you improve the way you do business." (Bernard Marr, ​​​​​​​"Data Strategy", 2017)

"Data for data’​​​​​​​s sake is meaningless. Therefore, instead of hoarding data, collect only what you really need and what makes business sense." (Bernard Marr, ​​​​​​​"Data Strategy", 2017) [?!] 

"Data is certainly exciting –​​​​​​​ revolutionary, even. But that doesn’​​​​​​​t always mean useful. To be truly useful, in a business sense, data must address a specific business need, help the organization reach its strategic goals, or generate real value." (Bernard Marr, ​​​​​​​"Data Strategy", 2017)

"[…] from a data strategy point of view, you need to describe the ideal data sets that would help you achieve your strategic objectives. You can then choose the best options for you based on how well they help you achieve your objectives, how easy it is to access or gather that data, and how cost effective it is." (Bernard Marr, ​​​​​​​"Data Strategy", 2017)

"However you plan to use data, even if you plan to treat data as a key business asset, it is never a good idea to capture huge mountains of data that you don’​​​​​​​t really need. Remember, the power of big data is not in the data it - self, it’​​​​​​​s in how you use it." (Bernard Marr, ​​​​​​​"Data Strategy", 2017) [?!] 

"I can’​​​​​​​t stress enough how important this stage is; ‘​​​​​​​selling’​​​​​​​ big data to your people is a crucial early step on your data journey. It instils confidence in data." (Bernard Marr, ​​​​​​​"Data Strategy", 2017) [?!] 

"[…] if companies want to avoid drowning in data, they need to develop a smart strategy that focuses on the data they really need to achieve their goals. In other words, this means defining the business-critical questions that need answering and then collecting and analysing only that data which will answer those questions." (Bernard Marr, ​​​​​​​"Data Strategy", 2017)

"Structured data is any data or information that is located in a fixed field within a defined record or file, usually in databases or spreadsheets. Essentially, it is data that is organized in a predetermined way, usually in rows and columns." (Bernard Marr, ​​​​​​​"Data Strategy", 2017)

"[…] the better insights are communicated, the more likely it is that data leads to positive action (in this case, better business decisions)." (Bernard Marr, ​​​​​​​"Data Strategy", 2017)

"Unfortunately, the widespread perception among business executives is that data and analytics are purely IT matters. And as with all IT matters, this means they don’​​​​​​​t really need to understand how they work, or why." (Bernard Marr, ​​​​​​​"Data Strategy", 2017)

"When data isn’​​​​​​​t properly looked after, it becomes meaningless and valueless. Even worse, if the data is out of date, incorrectly categorized, or used out of context, it can lead to misinformed decisions that can damage the long-term health of the company." (Bernard Marr, ​​​​​​​"Data Strategy", 2017) [?!] 

🎯Pradeep Menon - Collected Quotes

"A central node acts as a hub in the hub-spoke pattern, and many edge nodes act as the spoke. The hub is the central node that orchestrates and governs the data sharing between each of the spokes. Each spoke node can have its own data lakehouse. The way the spoke nodes are constructed depends on the organizational structure. It can be at a department level, a separate organizational unit, or even a sub-department within a large department." (Pradeep Menon, "Data Lakehouse in Action", 2022)

"A data sharing data service shares data, in any format and any size, from multiple sources within an organization or other organizations. This type of service provides the required control to share data and allows data-sharing policies to be created. It also enables data sharing in a structured manner and offers complete visibility into how the data is shared and how it is used. A data-sharing system uses APIs for data sharing." (Pradeep Menon, "Data Lakehouse in Action", 2022)

"A data lakehouse stores a lot of data. It stores data in the data lake layer and the serving layer in structured and unstructured formats. The data needs to be processed with different types of compute engines. It can be a batch-based compute or a stream-based compute. A tightly coupled compute and storage layer strips off the flexibility required in a data lakehouse. Decoupling compute and storage also has a cost implication - storage is cheap and persistent but compute is expensive and ephemeral. It gives you the flexibility to spin up compute services on-demand and scale them as required, and also gives better cost control and cost predictability." (Pradeep Menon, "Data Lakehouse in Action", 2022)

"A data warehouse service provides cleansed and transformed data that can be used for multiple purposes. First, it serves as a layer for reporting and BI. Second, it is a platform to query data for business or data analysis. Third, it serves as a repository to store historical data that needs to be online and available. Finally, it also acts as a source of transformed data for other downstream data marts that may cater to specific departmental requirements." (Pradeep Menon, "Data Lakehouse in Action", 2022)

"Advanced analytics pivots around machine learning methods. Machine learning employs statistical learning methods to perform analysis on data. These statistical methods utilize algorithms that predict what may happen based on historical data or extract complex mathematical relationships from data to generate insights." (Pradeep Menon, "Data Lakehouse in Action", 2022)

"An API is an interface that allows applications to interact with an external service using a simple set of commands. Data can also be served as part of API interaction. As the data is exposed to multiple external services, API-based methods can scale to share data securely with external services. Data through an API is served in JSON format, therefore the technology used to serve the data using APIs should be able to support JSON formats. For example, a NoSQL database can store such data." (Pradeep Menon, "Data Lakehouse in Action", 2022)

"Any change in the reporting requirement had to go through a long-winded process of data model changes, ETL code changes, and respective changes to the reporting system. Often, the ETL process was a specialized skill and became a bottleneck for reducing data to insight turnover time. The nature of analytics is unique. The more you see the output, the more you demand. Many EDW projects were deemed a failure. The failure was not from a technical perspective, but from a business perspective. Operationally, the design changes required to cater to these fast-evolving requirements were too difficult to handle." (Pradeep Menon, "Data Lakehouse in Action", 2022)

"Data architecture is the structure that enables the storage, transformation, exploitation, and governance of data." (Pradeep Menon, "Data Lakehouse in Action", 2022)

"Descriptive analytics takes the form of on-demand queries, standard reporting, self-service business intelligence, and data lake exploration. This category of analytics performs analytics on historical data by providing different points of view on the data. The points of view are created by aggregating and filtering the quantitative data (also called the measure), and slicing the data across attributes of functional dimensions, such as sales, customers, and products. We can deliver descriptive analytics in multiple formats such as files, cross tab reports, visual reports, or dashboards." (Pradeep Menon, "Data Lakehouse in Action", 2022)

"Each domain data lakehouse may opt to have its data catalog. However, the critical component in this architecture is the data mesh catalog. The data mesh catalog is the master catalog used to discover the data elements available in different nodes. Each domain-oriented node will donate its metadata to the data mesh catalog. This donation of metadata determines the effectiveness of the data mesh architecture. Once the metadata is contributed, other nodes can browse through the data mesh catalog. They can select the data of interest and mutually share data between the nodes through a governed data sharing process. The critical point to note here is that, unlike the hub-spoke architecture, the data mesh architecture enables data sharing between the 'spoke nodes'. There is no hub node in a data mesh architecture." (Pradeep Menon, "Data Lakehouse in Action", 2022)

"The AI-ML service allows data scientists to build, train and deploy production-ready AI-ML models. This layer also provides the framework to maintain and monitor such models. In addition, it gives the ability for teams to collaborate as they go about building these models. This service should be able to scale up and down as required and should be able to facilitate automatic model deployment and operations." (Pradeep Menon, "Data Lakehouse in Action", 2022)

"The data mesh pattern doesn't feature a central node and is loosely coupled compared to a hub-spoke architecture. It has different data lakehouse nodes that are independent of each other. The node data lakehouses are domain-driven. A domain can be oriented in multiple ways. The original idea of data mesh alludes to a source-oriented domain aligning to business processes. However, a more practical approach would be to define a domain based on the organizational setup and practicality; for example, a domain can be a product group, it can be separate organizational entities, and it can also be a specific business process, such as marketing. Each domain has its own data lakehouse that is managed and maintained by that domain." (Pradeep Menon, "Data Lakehouse in Action", 2022)

"A Data Lake is a centralized repository that allows you to store all your structured and unstructured data at any scale. You can store your data as-is without having first to structure the data and run different types of analytics  - from dashboards and visualizations to big data processing, real-time analytics, and machine learning to guide better decisions." (Pradeep Menon, "Data Mesh Principles, patterns, architecture, and strategies for data-driven decision making", 2024)

"A Data Lakehouse provides a unified platform for various data workloads, such as descriptive, predictive, and prescriptive analytics. It can handle structured and unstructured data and enforce schema at both read and write times, enabling traditional business intelligence tasks and advanced analytics on the same platform." (Pradeep Menon, "Data Mesh Principles, patterns, architecture, and strategies for data-driven decision making", 2024)

"A defining attribute of the domain-oriented ownership principle is the focus on context preservation in Data Management. This aspect accentuates the importance of keeping data within its native domain environment, allowing it to retain its original context, value, and meaning. When data is managed close to its source, its contextual richness is preserved. This sharply contrasts centralized models, where data is often abstracted from its source, leading to potential loss of signal or context. When data remains within its generating domain, it retains the nuances and specificities unique to its activities, challenges, and goals." (Pradeep Menon, "Data Mesh Principles, patterns, architecture, and strategies for data-driven decision making", 2024)

"A transformative perspective offered by the Data Mesh is envisioning data as a product. This section underscores the significance of curating data with the meticulousness and vision akin to product development, ensuring it delivers tangible value to its consumers. The ripple effects of this paradigm shift, spanning roles, processes, and technologies, are also meticulously unpacked." (Pradeep Menon, "Data Mesh Principles, patterns, architecture, and strategies for data-driven decision making", 2024)

"Centralized governance structures often have an abstract view of data, focusing more on uniformity and compliance than context and relevance. While these are essential elements, the nuance often needs to be noticed. Decentralized governance flips the script by giving data ownership to the domain that generates it. The domain has the richest understanding of the data’s context, relevance, and potential impact, thereby being well-positioned to enforce governance policies that improve data quality." (Pradeep Menon, "Data Mesh Principles, patterns, architecture, and strategies for data-driven decision making", 2024)

"Data Mesh also emphasizes aligning data products with business domains and use- cases to ensure that the data serves a clear business purpose and provides tangible value. Beforehand, we define the value proposition, target audience, quality attributes, and KPIs of each data product to ensure that it meets or exceeds the expectations of its consumers." (Pradeep Menon, "Data Mesh Principles, patterns, architecture, and strategies for data-driven decision making", 2024)

"Data Mesh emphasizes ensuring reliable, consistent, and interoperable data products. When data is treated as a product, quality is non-negotiable. High-quality data must meet the expectations and requirements of its users, both internally and externally. Additionally, data products must be designed with other products in mind, adhering to principles like loose coupling for easy interchangeability and high cohesion for strong functional relatedness. This feature enables the integration of different data products, ensuring seamless interoperability and greater usability. Data products should be reliable, complete, accurate, and accurate. They should also be integrated, compatible, and consistent rather than isolated, incompatible, or conflicting." (Pradeep Menon, "Data Mesh Principles, patterns, architecture, and strategies for data-driven decision making", 2024)

"[...] domain-oriented ownership empowers individual domains to create and adapt their data strategies with agility, with a thorough understanding of their business needs and market demands. Whether pivoting due to a new competitor’s actions or adjusting to a sudden change in consumer behavior, domains can independently and swiftly modify their data strategies, providing them with a unique edge in the marketplace." (Pradeep Menon, "Data Mesh Principles, patterns, architecture, and strategies for data-driven decision making", 2024)

"Domain-oriented ownership is a core principle of data mesh. It entails that data producers, experts in their business domains, are responsible for the entire lifecycle of their produced data. Specifically, they take ownership of the data from the point of ingestion through transformation, serving, quality assurance, and governance. Moreover, they are responsible for the data products created from their data, which serve as units of data consumption for other domains or users." (Pradeep Menon, "Data Mesh Principles, patterns, architecture, and strategies for data-driven decision making", 2024)

"Domain autonomy should not be mistaken for a lack of governance or accountability. Autonomy, in this context, implies a higher level of responsibility. Domains are free to act and accountable for their actions, especially regarding how well their data strategies align with domain-specific and broader organizational objectives." (Pradeep Menon, "Data Mesh Principles, patterns, architecture, and strategies for data-driven decision making", 2024)

"Empowering with self-serve data infrastructure: The Data Mesh champions the ethos of self-reliance. By empowering teams to construct and oversee their data infrastructure, organizations can foster a culture of speed, autonomy, and accountability." (Pradeep Menon, "Data Mesh Principles, patterns, architecture, and strategies for data-driven decision making", 2024)

"Governance refers to an organization’s framework to exercise direction and control over a specific domain. In the context of data, it could include rules, protocols, and systems to manage data quality, security, and accessibility."  (Pradeep Menon, "Data Mesh Principles, patterns, architecture, and strategies for data-driven decision making", 2024)

"In a centralized model, changes to data strategy often require navigating through bureaucratic layers and rigid governance structures. This delays adaptability and increases the risk of misalignment between what the data strategy aims to achieve and what the business needs. Centralized models are typically disconnected from the ground realities of individual business units, leading to a generic, one-size-fits-all approach that seldom caters to unique market challenges or opportunities." (Pradeep Menon, "Data Mesh Principles, patterns, architecture, and strategies for data-driven decision making", 2024)

"Promoting domain-oriented ownership is to combat the common problem of organizational silos. Silos can significantly hinder the free flow of data and expertise, making decision-making and innovation more challenging. We aim to break down these barriers by advocating for domain-oriented ownership and creating a more dynamic and collaborative data management landscape." (Pradeep Menon, "Data Mesh Principles, patterns, architecture, and strategies for data-driven decision making", 2024)

"The allure of Data Lakes was their ability to store vast amounts of raw data. However, this advantage can become counterproductive without stringent governance and management protocols. In their zeal to harness the power of Big Data, some organizations indiscriminately dump data into their lakes. Without proper classification, curation, and quality checks, these lakes can become swamps - murky repositories filled with valuable data, redundant information, and outdated datasets. Navigating these data swamps becomes a significant challenge, leading to prolonged data retrieval times, increased chances of using obsolete or incorrect data, and a decline in the agility and efficiency of data-driven decision-making processes rather than facilitating quick and insightful analytics." (Pradeep Menon, "Data Mesh Principles, patterns, architecture, and strategies for data-driven decision making", 2024)

"When data is considered a product, it creates opportunities for collaboration across different domains. This collaboration involves working with other teams to create, share, and use data products that span multiple areas of expertise, interest, or value. Data Mesh promotes cross-domain collaboration by focusing on the consumers rather than the producers. Data products are made available through standardized interfaces and protocols that support various modes of consumption and are governed by domain experts who understand the context and nuances of their data." (Pradeep Menon, "Data Mesh Principles, patterns, architecture, and strategies for data-driven decision making", 2024)

🎯Fadi Maali - Collected Quotes

"A common mistake when implementing a data catalog is to focus only on technical metadata. This limits its use and the potential value. It also excludes business users who have valuable related input or need to use the catalog. A catalog should in fact function as a two-way translation layer between technical and business users." (Fadi Maali & Jason Lim, "Implementing a Modern Data Catalog to Power Data Intelligence: Make Trustworthy Data Central to Your Organization", 2022)

"A core premise of data mesh is federating data ownership among domain data owners who are responsible for their data as a product. Offering the data as a product requires the data to be discoverable and to have explicitly stated quality characteristics and a clearly defined access method. Such requirements are at the core of what data catalogs support. With support for data labeling, curation, and crowdsourced feedback, data catalogs are well positioned to offer data as a product. Furthermore, data catalogs support the enforcement of compliant data usage, which becomes more important when data ownership is not managed centrally." (Fadi Maali & Jason Lim, "Implementing a Modern Data Catalog to Power Data Intelligence: Make Trustworthy Data Central to Your Organization", 2022)

"Active governance guides users as they find and use data. A data catalog with active governance will surface compliance information about sensitive data at point of use, so as to encourage users to use canonical and high-quality data assets; it will also provide a way to ask domain experts for help. They actively help users to ensure compliant usage of data with features such as masking, which anonymizes PII for given user personas who are restricted from viewing it per the GDPR." (Fadi Maali & Jason Lim, "Implementing a Modern Data Catalog to Power Data Intelligence: Make Trustworthy Data Central to Your Organization", 2022)

"Build a community around the catalog. Make sure data producers, stewards, and consumers are all involved and empowered to enrich the content of the catalog. Establish a leader or a team to have clear ownership of the data catalog." (Fadi Maali & Jason Lim, "Implementing a Modern Data Catalog to Power Data Intelligence: Make Trustworthy Data Central to Your Organization", 2022)

"Data catalog platforms take a more holistic view to focus not only on data assets within an enterprise, but also on the surrounding ecosystem (including business and people elements). They are typically characterized by an extensible data model that can grow to define various assets and concepts, such as metrics, charts, AI features, and users. Data catalog platforms typically augment their data with a focus on business and users to support collaborative governance and enrichment of metadata and to interlink data with business glossaries and dictionaries. Moreover, they are architected to make them easily integrable with other systems." (Fadi Maali & Jason Lim, "Implementing a Modern Data Catalog to Power Data Intelligence: Make Trustworthy Data Central to Your Organization", 2022)

"Data catalogs that focus on governance are concerned mainly with controlling data access and ensuring that data is used according to defined policies; this includes external policies such as data privacy laws as well as policies defined with an enterprise. Those catalogs apply techniques to identify data assets with sensitive information and to monitor data flow and access." (Fadi Maali & Jason Lim, "Implementing a Modern Data Catalog to Power Data Intelligence: Make Trustworthy Data Central to Your Organization", 2022)

"Data catalogs that focus on search bring techniques and methods from information retrieval and web search engines to the data domain within enterprises. Some of those catalogs, such as Facebook Nemo, use advanced machine learning and NLP tools to provide personalized search of data within an enterprise. The search can also use data-specific signals such as usage, popularity, and freshness to rank data assets by usefulness." (Fadi Maali & Jason Lim, "Implementing a Modern Data Catalog to Power Data Intelligence: Make Trustworthy Data Central to Your Organization", 2022)

"Enterprises typically become interested in data catalogs when they have a specific use case or need in mind. Data governance, self-service analytics, and cloud data migration are common examples. Having a specific need or use case helps focus efforts and measure impact. However, as with other technical efforts within enterprises, it is essential to prepare for long-term sustainable success and to have a plan to maximize successful adoption." (Fadi Maali & Jason Lim, "Implementing a Modern Data Catalog to Power Data Intelligence: Make Trustworthy Data Central to Your Organization", 2022)

"Historically, for their analytics needs, enterprises relied upon a set of tightly coupled tools, typically provided by a single vendor. Nowadays, nearly all of the components of a traditional data warehouse are independent and interchangeable. Those independent tools can be flexibly combined to provide a modern data stack. It is common for current enterprises to have separate tools for data ingestion, data pipelines, data storage and querying, data visualization and business intelligence, and data quality. Furthermore, data can flow in the opposite direction out of the data warehouse in what is referred to as reverse extract, transform, and load (ETL)." (Fadi Maali & Jason Lim, "Implementing a Modern Data Catalog to Power Data Intelligence: Make Trustworthy Data Central to Your Organization", 2022)

"In a self-service environment with multiple publishers, it’s impossible to completely avoid data redundancy and overlapping. Multiple data assets with similar content, but possibly with varying quality, will exist. A data catalog can guide users to trusted data that comes from a reliable source and is frequently used. A data catalog can also use various explicit and implicit quality signals when ranking datasets for recommendation. Some of those signals are discussed next. Furthermore, a data catalog can recommend domain experts who are automatically identified based on actual data usage." (Fadi Maali & Jason Lim, "Implementing a Modern Data Catalog to Power Data Intelligence: Make Trustworthy Data Central to Your Organization", 2022)

"It is often said that data scientists and data analysts spend only 20% of their time doing data analysis work, with 80% consumed by data 'issues'. The bulk of their time is spent finding, evaluating, understanding, and preparing data before analysis can begin. A data catalog inverts this principle by enabling data analysts and data scientists to spend 20% of their time looking for data and 80% performing analysis." (Fadi Maali & Jason Lim, "Implementing a Modern Data Catalog to Power Data Intelligence: Make Trustworthy Data Central to Your Organization", 2022)

"Self-service BI initiatives help organizations become more data-driven and democratize access to data. But data can’t be used if it can’t be found. Search and discovery of trustworthy data is a core value of enterprise data catalogs, and the value extends well beyond business users."

🎯🏭🗒️Sonia Mezzetta - Collected Quotes

"A data architecture needs to have the robustness and ability to support multiple data management and operational models to provide the necessary business value and agility to support an enterprise’s business strategy and capabilities." (Sonia Mezzetta, "Principles of Data Fabric: Become a data-driven organization by implementing Data Fabric solutions efficiently", 2023)

"A data strategy must align with the business goals and overall framework of how data will be used and managed within an organization. It needs to include standards for how data will be discovered, integrated, accessed, shared, and protected. It needs to address how data will meet regulatory compliance policies, Master Data Management, and data democratization. There needs to be an assurance that both data and metadata have a quality control framework in place to achieve data trust. A data strategy needs to have a clear path on how an organization will accomplish data monetization." (Sonia Mezzetta, "Principles of Data Fabric: Become a data-driven organization by implementing Data Fabric solutions efficiently", 2023)

"A data strategy is a living document that needs to be continuously updated to align with business goals. It should have a clear maintenance process with frequent reviews and identification of authors and stakeholders that will contribute to the data strategy. This also includes the handling of exceptions to a data strategy process for any one-off decisions in special circumstances. A data strategy document must always be easily assessable, to the point, and understandable." (Sonia Mezzetta, "Principles of Data Fabric: Become a data-driven organization by implementing Data Fabric solutions efficiently", 2023)

"Apply DataOps principles to the development and delivery of data. DataOps is a best practice framework that accelerates the development of data and quality across its entire life cycle with high efficiency and quality. This is especially important when integrating data across distributed complex systems and environments." (Sonia Mezzetta, "Principles of Data Fabric: Become a data-driven organization by implementing Data Fabric solutions efficiently", 2023)

"Automated data orchestration is a key DataOps principle. An example of orchestration can take ETL jobs and a Python script to ingest and transform data based on a specific sequence from different source systems. It can handle the versioning of data to avoid breaking existing data consumption pipelines already in place." (Sonia Mezzetta, "Principles of Data Fabric: Become a data-driven organization by implementing Data Fabric solutions efficiently", 2023)

"Data Fabric’s building blocks represent groupings of different components and characteristics. They are high-level blocks that describe a package of capabilities that address specific business needs. The building blocks are Data Governance and its knowledge layer, Data Integration, and Self-Service." (Sonia Mezzetta, "Principles of Data Fabric: Become a data-driven organization by implementing Data Fabric solutions efficiently", 2023)

"Data Fabric is a composable architecture made up of different tools, technologies, and systems. It has an active metadata and event-driven design that automates Data Integration while achieving interoperability. Data Governance, Data Privacy, Data Protection, and Data Security are paramount to its design and to enable Self-Service data sharing. The following figure summarizes the different characteristics that constitute a Data Fabric design." (Sonia Mezzetta, "Principles of Data Fabric: Become a data-driven organization by implementing Data Fabric solutions efficiently", 2023)

"Data Fabric focuses on Self-Service data access via active metadata leveraging a composable set of tools and technologies. It offers the ability to discover, understand, and access data across hybrid and multi-cloud data landscapes with automation and Data Governance. It is primarily process and technology centric with flexibility in supporting diverse organizational models. On the other hand, Data Mesh is organizationally and process driven. It requires a technical implementation approach to execute its design. Data Mesh is at a higher level and Data Fabric is at a lower level. Data Fabric is capable of fulfilling Data Mesh’s key principles." (Sonia Mezzetta, "Principles of Data Fabric: Become a data-driven organization by implementing Data Fabric solutions efficiently", 2023)

"Data Fabric is a distributed and composable architecture that is metadata and event driven. It’s use case agnostic and excels in managing and governing distributed data. It integrates dispersed data with automation, strong Data Governance, protection, and security. Data Fabric focuses on the Self-Service delivery of governed data." (Sonia Mezzetta, "Principles of Data Fabric: Become a data-driven organization by implementing Data Fabric solutions efficiently", 2023)

"Data Fabric is a distributed data architecture that connects scattered data across tools and systems with the objective of providing governed access to fit-for-purpose data at speed. Data Fabric focuses on Data Governance, Data Integration, and Self-Service data sharing. It leverages a sophisticated active metadata layer that captures knowledge derived from data and its operations, data relationships, and business context. Data Fabric continuously analyzes data management activities to recommend value-driven improvements. Data Fabric works with both centralized and decentralized data systems and supports diverse operational models." (Sonia Mezzetta, "Principles of Data Fabric: Become a data-driven organization by implementing Data Fabric solutions efficiently", 2023)

"[Data Fabric] is not a single technology, such as data virtualization. […] It is not a single tool like a data catalog and it doesn’t have to be a single data storage system like a data warehouse. It represents a diverse set of tools, technologies, and storage systems that work together in a connected ecosystem via a distributed data architecture, with active metadata as the glue. It doesn’t just support centralized data management but also federated and decentralized data management. It excels in connecting distributed data. Data Fabric is not the same as Data Mesh. They are different data architectures that tackle the complexities of distributed data management using different but complementary approaches." (Sonia Mezzetta, "Principles of Data Fabric: Become a data-driven organization by implementing Data Fabric solutions efficiently", 2023)

"Data Fabric supports a federated, decentralized, or centralized organization. To participate in Data Fabric, metadata is contributed in an automated manner and knowledge is populated from it to propel data management. Data Fabric is different from a Data Mesh design in that it supports decentralized, federated, and centralized organizations. Data Fabric’s objectives are to help an organization to evolve to a more mature level of data management by leveraging active metadata, which is a core prerequisite." (Sonia Mezzetta, "Principles of Data Fabric: Become a data-driven organization by implementing Data Fabric solutions efficiently", 2023)

"Data Mesh is a design concept based on federated data and business domains. It applies product management thinking to data management with the outcome being Data Products. It’s technology agnostic and calls for a domain-centric organization with federated Data Governance." (Sonia Mezzetta, "Principles of Data Fabric: Become a data-driven organization by implementing Data Fabric solutions efficiently", 2023)

"Establish an organization’s data maturity level and progress toward ongoing improvement. An organization needs to first understand what its current data maturity level is to determine the areas of improvement to create a forward-looking plan. A data maturity assessment offers a position on the current data maturity that serves as an indicator of the health of an organization. A data maturity assessment can be used as a tool to drive continuous improvement by measuring progress. The key thing here is to always strive for continuous improvement to achieve success." (Sonia Mezzetta, "Principles of Data Fabric: Become a data-driven organization by implementing Data Fabric solutions efficiently", 2023)

"I emphasize this point as there are views in the industry that Data Fabric is a centralized storage architecture, which is not the case from my point of view. A Data Fabric architecture is driven by the needs and direction of the business architecture." (Sonia Mezzetta, "Principles of Data Fabric: Become a data-driven organization by implementing Data Fabric solutions efficiently", 2023)

"Manage data as a strategic asset that evolves into a data product. The premise here is to stop managing data as a byproduct and create an ecosystem that manages data as a valuable strategic asset that can evolve into a data product. Data producers are accountable for managing the life cycle of data from creation to end of life and ensuring it creates business value along the way for data consumers. This requires data that is governed, trusted, protected, secure, and easily accessible. Move data from technical data assets to Data Products by operationalizing data for high scale sharing." (Sonia Mezzetta, "Principles of Data Fabric: Become a data-driven organization by implementing Data Fabric solutions efficiently", 2023)

"Where Data Mesh differs from Data Fabric is that it has fixed requirements for the Self-Service platform focused on organizing and managing Data Products by business domain. Another difference is Data Fabric supports managing data as an asset and as a product. A Data Product can be composed of assets that have been governed and managed in a Data Fabric architecture. Data Fabric does not have these fixed requirements, although it inherently supports isolating data and Data Governance enforcement via metadata by business domain. You can think of a Data Mesh Self-Service data platform as supporting separate, independent companies (business domains), although the key criteria are that it does not create data silos and attains data sharing across these companies in a secure, quick, and easy manner. In Data Mesh, Data Products are created and managed by federated business domains and a data platform requires capabilities that enable data and policy federation. This is where a Data Fabric solution can also address Data Mesh’s requirements." (Sonia Mezzetta, "Principles of Data Fabric: Become a data-driven organization by implementing Data Fabric solutions efficiently", 2023)

🔢Charles D Tupper - Collected Quotes

"Data architectures are the heart of business functionality. Given the proper data architecture, all possible functions can be completed within the enterprise easily and expeditiously." (Charles D Tupper, "Data Architecture: From Zen to Reality", 2011)

"Processes that use data change far more frequently than the data structures themselves." (Charles D Tupper, "Data Architecture: From Zen to Reality", 2011)

"The enterprise architecture delineates the data according to the inherent structure within the organization rather than by organizational function or use. In this manner it makes the data dependent on business objects but independent of business processes." (Charles D Tupper, "Data Architecture: From Zen to Reality", 2011)

"Using architecture leads to foundational stability, not rigidity. As long as the appropriate characteristics are in place to ensure positive architectural evolution, the architecture will remain a living construct. Well-developed architectures are frameworks that evolve as the business evolves." (Charles D Tupper, "Data Architecture: From Zen to Reality", 2011)
