Materialized View

A materialized view is a database object that stores the result of a precomputed query. Unlike regular views, which are virtual and don't store data themselves, materialized views physically store the query result, allowing for faster access to the data. Materialized views are especially useful in scenarios where the underlying data is relatively stable, and the cost of running complex queries in real-time is high.
