DBMS: Views (Definitions)

"An alternative way of looking at the data in one or more tables. Usually created as a subset of columns from one or more tables." (Karen Paulsell et al,  "Sybase SQL Server: Performance and Tuning Guide", 1996)

"Predefined query that provides an alternative method of looking at the data in one or more underlying tables. Typically views are used to focus a users view of data and for security." (Rob Scrimger et al, "MCSE TestPrep: SQL Server 6.5  Administration", 1998)

"An alternate way of looking at data from one or more tables in the database. A view is a virtual table, usually created as a subset of columns from one or more tables, which is expressed as a SELECT statement. Depending on the definition, data in base tables can be modified through views." (Microsoft Corporation, "Microsoft SQL Server 7.0 System Administration Training Kit", 1999)

"A 'virtual table', usually referring to a database object that has been named and created with SQL's CREATE VIEW statement. Usually created for read-only purposes, it is possible to update the database through some views; as of Oracle8, it is also possible to associate an INSTEAD OF trigger with a view to allow INSERT, UPDATE, and DELETE operations on the view." (Bill Pribyl & Steven Feuerstein, "Learning Oracle PL/SQL", 2001)

"SQL statement that creates logical copies of a table or a complete query that can be used separately in a SELECT statement. Views are semantically independent, so the separate roles of a dimension usually are implemented as views." (Ralph Kimball & Margy Ross, "The Data Warehouse Toolkit" 2nd Ed., 2002)

"A database object that can be referenced the same way as a table in SQL statements. Views are defined using a SELECT statement and are analogous to an object that contains the result set of this statement." (Anthony Sequeira & Brian Alderman, "The SQL Server 2000 Book", 2003)

"A view is a relational database object that can be referenced and built by using SELECT statements to join data from one or more base tables. Views are similar to tables in that data can be retrieved and modified and indexes can be built." (Thomas Moore, "MCSE Training Guide 70-229: Designing and Implementing Databases with Microsoft® SQL Server™ 2000 Enterprise Edition", 2003)

"A database object that is based on a SELECT statement against one or more tables or other views in the database. A regular view does not store any data in the database; only the definition is stored. Views are also known as stored queries." (Bob Bryla, "Oracle Database Foundations", 2004)

"A relational database object that can be referenced and built by using SELECT statements to join data from one or more base tables. Views are similar to tables in that data can be retrieved and modified and indexes can be built." (Thomas Moore, "MCTS 70-431: Implementing and Maintaining Microsoft SQL Server 2005", 2006) 

"A query that is stored in the data dictionary and is rerun when called for. A view appears to a user to be a table." (Sikha S Bagui & Richard W Earp, "Learning SQL on SQL Server 2005", 2006)

"virtual representations of a table whose contents are defined by a query" (Joseph L Jorden & Dandy Weyn, "MCTS Microsoft SQL Server 2005: Implementation and Maintenance Study Guide - Exam 70-431", 2006)

 "A database object in SQL Server used to encapsulate a query. Commonly referred to as a virtual table." (Marilyn Miller-White et al, "MCITP Administrator: Microsoft SQL Server 2005 Optimization and Maintenance 70-444" , 2007)

"A virtual table which is derived from base table using a query." (S. Sumathi & S. Esakkirajan, "Fundamentals of Relational Database Management Systems", 2007)

"A virtual grouping of one or more tables, often done to reduce complexity while increasing security and reliability." (Robert D. Schneider & Darril Gibson, "Microsoft SQL Server 2008 All-In-One Desk Reference For Dummies", 2008)

"A stored SQL query from which a virtual table is created for use each time the name of the view is used." (Jan L Harrington, "SQL Clearly Explained" 3rd Ed., 2010)

"A virtual table consisting of columns and selected instances from other tables assembled in a systematic way." (David C Hay, "Data Model Patterns: A Metadata Map", 2010)

"A presentation of a set of data from one or more physical tables as one logical table. A view can include some or all the rows and columns from each contributing table, and can be defined as the result table from a SELECT statement." (DAMA International, "The DAMA Dictionary of Data Management", 2011)

"A virtual table, defined as a SQL SELECT statement, to provide a subset of data from one or more tables." (Craig S Mullins, "Database Administration" 2nd Ed, 2012)

"A virtual table that uses the result set of a saved query." (Faisal Akkawi et al, "MCSA Guide to Microsoft SQL Server 2012 - Exam #70-462", 2014)

"A database object that is created from one or more tables and can be used the same as a table. A view is a virtual table that has no storage requirements of its own." (Arie D Jones, "SQL in 24 Hours" 6th Ed., 2015)

"A virtual relation defined by the database administrator in order to keep subjects from viewing certain data." (Adam Gordon, "Official (ISC)2 Guide to the CISSP CBK 4th Ed.", 2015)
