VIEWS in SQL
A View in SQL is a virtual table created by a query. Views allow you to simplify complex queries, enhance security by restricting access to specific columns, and provide a way to customize data presentation without altering the underlying tables. Unlike tables, views do not store data physically but instead store a query that generates the data on demand.
