Abstract

Shared materialized views are maintained during data changes to the primary data and during creation of new materialized views. Shared data stored for use by shared materialized views is distinguished from data stored by an independent materialized view. A view selector manages data updates to shared materialized views and corresponding mapping table. The view selector directs movement of data between a shared materialized view and an independent materialized view through the lifecycle of the materialized views.
