Materialized views can perform a number of roles, such as improving query performance or providing replicated data. Prior to Oracle 12c, materialized views used traditional refresh methods where changes were applied to the base tables and then the materialized views were refreshed separately with one of several methods. Synchronous refresh is a new approach in Oracle 12c R1 for maintaining tables and materialized views where tables and materialized views are refreshed at the same time. This webinar will discuss the benefits of the synchronous refresh method along with how to implement it.
