Scenario: A DBA is troubleshooting a performance issue in a database with frequent INSERT, UPDATE, and DELETE operations. Describe how using materialized views can help reduce the overhead on these operations and improve overall database performance.

Materialized views can help reduce the overhead on frequent INSERT, UPDATE, and DELETE operations in a database by precomputing and storing the results of queries. This reduces the need to perform expensive computations during query execution, as the results are readily available in the materialized views. By eliminating the need to access the underlying base tables, materialized views improve query performance and response time, enhancing overall database performance. Additionally, materialized views enhance data consistency and accuracy by providing a snapshot of data at a specific point in time, ensuring that queries retrieve consistent and up-to-date information. Furthermore, materialized views simplify data access and retrieval by aggregating and summarizing information from multiple tables, making it easier to query and analyze data.
