Materialization View in DBMS
A materialization view is nothing but a snapshot or materialized query table. It is a database object that stores the results of the query table. Materialized views in the Database Management System (DBMS) work as the existing snapshots of the data, reducing the computational overhead. Unlike standard views, which are data that is virtually dynamically generated when the materialization view contains original data that exists in the database until the data is modified or truncated.
