If we have several tables in a DB and we want to view only
specific columns from specific tables we can go for
views.It would also suffice the needs of security sometimes
allowing specific users to see only specific columns based
on the permission that we can configure on the view. Views
also reduce the effort that is required for writing queries
to access specific columns every time
