# OLAP Catalog Metadata Cache

The OLAP Catalog views present information stored in the base tables of the OLAP Catalog. This information is also stored for fast access in a separate set of cache tables.

The OLAP Catalog views are named with the `ALL_OLAP2` or `DBA_OLAP2` prefix. The views of the cache tables, which have the same column structure, are named with the `MRV_OLAP2` prefix.

Applications that require fast access to OLAP Catalog metadata should query the cached metadata in the `MRV_OLAP2` views.

The metadata cache is not automatically refreshed when changes are made to the base metadata tables. To refresh the cache, use the `CWM2_OLAP_METADATA_REFRESH` package.

Note: If your data is stored in relational tables (not in analytic workspaces), you must refresh the OLAP Catalog metadata cache for applications that use the OLAP API.
