A materialized view can combine all of that into a single result set that’s stored like a table. In Oracle 8i, snapshots were renamed to materialized views, and updatable snapshots became updatable materialized views. and hence, they need a refresh mechanism.

Materialized View: Unlike a view, a materialized view has a concrete existance, in the sence that the tables are pre-joined and aggreations made and the results of the query are stored on disk. A materialized view log was created for the employee table, so Oracle Database performs a fast refresh of the materialized view every 7 days, beginning 7 days after the materialized view is created. Materialized views are a really useful performance feature, allowing you to pre-calcuate joins and aggregations, which can make applications and reports feel more responsive. It stores data physically and get updated periodically. Without a materialized views log, Oracle Database must re-execute the materialized view query to refresh the materialized views.
