⛏️Data Management: Data Structure (Definitions)

"A logical relationship among data elements that is designed to support specific data manipulation functions (trees, lists, and tables)." (William H Inmon, "Building the Data Warehouse", 2005)

"Data stored in a computer in a way that (usually) allows efficient retrieval of the data. Arrays and hashes are examples of data structures." (Michael Fitzgerald, "Learning Ruby", 2007)

"A data structure in computer science is a way of storing data to be used efficiently." (Sahar Shabanah, "Computer Games for Algorithm Learning", 2011)

"Data structure is a general term referring to how data is organized. In modeling, it refers more specifically to the model itself. Tables are referred to as 'structures'." (Laura Sebastian-Coleman, "Measuring Data Quality for Ongoing Improvement ", 2012)

[probabilistic *] "A data structure which exploits randomness to boost its efficiency, for example skip lists and Bloom filters. In the case of Bloom filters, the results of certain operations may be incorrect with a small probability." (Wei-Chih Huang & William J Knottenbelt, "Low-Overhead Development of Scalable Resource-Efficient Software Systems", 2014)

"A collection of methods for storing and organizing sets of data in order to facilitate access to them. More formally data structures are concise implementations of abstract data types, where an abstract data type is a set of objects together with a collection of operations on the elements of the set." (Ioannis Kouris et al, "Indexing and Compressing Text", 2015)

"A representation of the logical relationship between elements of data." (Adam Gordon, "Official (ISC)2 Guide to the CISSP CBK" 4th Ed., 2015)

"Is a schematic organization of data and relationship to express a reality of interest, usually represented in a diagrammatic form." (Maria T Artese  Isabella Gagliardi, "UNESCO Intangible Cultural Heritage Management on the Web", 2015)

"The implementation of a composite data field in an abstract data type" (Nell Dale & John Lewis, "Computer Science Illuminated" 6th Ed., 2015)

"A way of organizing data so that it can be efficiently accessed and updated." (Vasileios Zois et al, "Querying of Time Series for Big Data Analytics", 2016)

"A particular way of storing information, allowing to a high level approach on the software implementation." (Katia Tannous & Fillipe de Souza Silva, "Particle Shape Analysis Using Digital Image Processing", 2018)

"It is a particular way of organizing data in a computer so that they can be used efficiently." (Edgar C Franco et al, "Implementation of an Intelligent Model Based on Machine Learning in the Application of Macro-Ergonomic Methods...", 2019)

"Way information is represented and stored." (Shalin Hai-Jew, "Methods for Analyzing and Leveraging Online Learning Data", 2019)

"A physical or logical relationship among a collection of data elements." (IEEE 610.5-1990)
