A view is a database subset that is created as a result of a user query and saved as a permanent object. In a SQL database, for example, a view becomes a form of virtual table with filtered rows and fields that match the real database's.

Because they encapsulate the table's name, views are utilised for security. Data is kept in a virtual table rather than being saved permanently. Views show only the info that you want to see. In order to derive the data for the view, we may also use Sql Joins in the Select statement.

A View is similar to a window through which data from tables can be viewed or updated, but it does not contain any data of its own. BASE Tables are the tables that a View is built on. In SQL, there are two sorts of views: simple and complex. Only one base table can be used in simple views.

A database view is a subset of a database that is based on one or more database tables and is based on a query. Database views are named queries that are stored in the database and can be used to save frequently performed, sophisticated queries. Dynamic views and static views are the two forms of database views.

VIEW is a virtual table that allows you to see a subset of the data from one or more tables. A view does not have any data of its own.
