  • Ans. 

    Views in DBMS are virtual tables that display data from one or more tables.

    • Views are created using SELECT statements.

    • They can be used to simplify complex queries.

    • Views can also be used to restrict access to sensitive data.

    • They do not store data themselves, but rather display data from other tables.

    • Changes made to the underlying tables are reflected in the view.
