Benefits of Materialization
- Reduced Database load database: The results of the query are stored in the materialization view; there is no need to recompute the data each time a view is accessed. It reduces the workload of a database server and improves the utilization of the resource and its scalability.
- Improved Performance: Storing the query results and materialization view decreases the computational overhead combined with executing difficult queries repeatedly. This improves the execution time of the query and leads to better overall performance for the system.
- Enhanced Query Flexibility: Materialization views are also used to denormalize the data, make difficult calculations, and aggregate information, enabling users to execute queries against the dataset easily.
- Offline Availability: The materialization calculations and the view can provide access to the results of the queries when the data is inaccessible or unavailable. This benefit contains the availability of data and enables the applications to perform efficient operations at the time of database maintenance or at the time of downloading from the server.
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.
