What is a view in the database
A view is a virtual table defined by a SELECT query. It does not store data itself but provides a saved query that you can reference like a regular table. Views are useful for simplifying complex joins, restricting access to specific columns or rows, and presenting a consistent interface even when the underlying table structure changes.
