"A component of a SQL Server Integration Services package that controls the flow of data within the package." (Marilyn Miller-White et al, "MCITP Administrator: Microsoft® SQL Server™ 2005 Optimization and Maintenance 70-444", 2007)
"Activities of a business process may exchange data during the execution of the process. The data flow graph of the process connects activities that exchange data and - in some notations - may also represent which input/output parameters of the activities are involved." (Cesare Pautasso, "Compiling Business Process Models into Executable Code", 2009)
"Data dependency and data movement between process steps to ensure that required data is available to a process step at execution time." (Christoph Bussler, "B2B and EAI with Business Process Management", 2009)
[logical data flow:] "A data flow diagram that describes the flow of information in an enterprise without regard to any mechanisms that might be required to support that flow." (David C Hay, "Data Model Patterns: A Metadata Map", 2010)
[physical data flow:] "A data flow diagram that identifies and represents data flows and processes in terms of the mechanisms currently used to carry them out." (David C Hay, "Data Model Patterns: A Metadata Map", 2010)
"The fact that data, in the form of a virtual entity class, can be sent from a party, position, external entity, or system process to a party, position, external entity, or system process." (David C Hay, "Data Model Patterns: A Metadata Map", 2010)
"An abstract representation of the sequence and possible changes of the state of data objects, where the state of an object is any of: creation, usage, or destruction [Beizer]." (International Qualifications Board for Business Analysis, "Standard glossary of terms used in Software Engineering", 2011)
"Data flow refers to the movement of data from one purpose to another; also the movement of data through a set of systems, or through a set of transformations within one system; it is a nontechnical description of how data is processed. See also Data Chain." (Laura Sebastian-Coleman, "Measuring Data Quality for Ongoing Improvement ", 2012)
"The movement of data through a group of connected elements that extract, transform, and load data." (Microsoft, "SQL Server 2012 Glossary", 2012)
"A path that carries packets of information of known composition; a roadway for data. Every data flow’s composition is recorded in the data dictionary." (James Robertson et al, "Complete Systems Analysis: The Workbook, the Textbook, the Answers", 2013)
"the path, in information systems or otherwise, through which data move during the active phase of a study." (Meredith Zozus, "The Data Book: Collection and Management of Research Data", 2017)
"The lifecycle movement and storage of data assets along business process networks, including creation and collection from external sources, movement within and between internal business units, and departure through disposal, archiving, or as products or other outputs." (Kevin J Sweeney, "Re-Imagining Data Governance", 2018)
"A graphical model that defines activities that extract data from flat files or relational tables, transform the data, and load it into a data warehouse, data mart, or staging table." (Sybase, "Open Server Server-Library/C Reference Manual", 2019)
"An abstract representation of the sequence and possible changes of the state of data objects, where the state of an object is any of: creation, usage, or destruction." (Software Quality Assurance)
