SQL VIEW Meaning and
Definition
-
A SQL view refers to a virtual table created within a database, which is a result of an SQL query. It is a logical representation of the data stored in one or more tables, and can be queried and manipulated like any other table in the database.
Views do not store actual data; instead, they are defined by using a SELECT statement, which allows users to retrieve specific data from one or more tables. The retrieved data is stored within the view temporarily, and can be used to simplify complex queries and provide a more organized and simplified presentation of the data.
Views can be considered as a reusable query, as they allow users to extract and analyze specific data from one or multiple tables, without the need of writing complex queries each time. They provide an abstraction layer over the underlying tables, which helps in enhancing security by restricting access to sensitive data for certain users or roles.
Modifying data through a view is also possible, depending on the definition of the view and the underlying tables. However, it is important to note that changes made through a view affect the underlying data, and vice versa. Views are often used to hide complexity, improve performance, and provide a more user-friendly interface to the database.

Etymology of SQL VIEW
The term "SQL view" does not have a distinct etymology, as it is a combination of two separate components:
1. SQL: SQL, which stands for Structured Query Language, is a programming language used for managing and manipulating relational databases. It was first developed in the early 1970s by Donald D. Chamberlin and Raymond F. Boyce at IBM Research.
2. View: In the context of databases, a view is a virtual table derived from an underlying table or tables. It does not store any data itself but displays the results of a query. The term "view" comes from the concept of looking at the data from a different perspective or angle. It allows users to simplify complex queries, retrieve specific information, and provide a layer of abstraction for data manipulation.
