You can save and retrieve BI Beans components to the BI Beans Catalog through either of the following systems:
The persistence service provides access to the BI Beans Catalog. You can use the persistence service even if you do not use OLAP metadata. For example, if you provide your own data source to display data in a graph, you can use the persistence service to save the graph to the Catalog.
The MetadataManager bean provides access to OLAP Services and, through the persistence service, to the Catalog. Use the MetadataManager if you use OLAP metadata. The QueryManager, QueryBuilder, and CalcBuilder beans require a MetadataManager for access to metadata. The MetadataManager consolidates access to the Catalog and access to the OLAP service. If your program needs OLAP metadata, then you should save and retrieve objects through the MetadataManager.
Both the persistence service and the MetadataManager bean implement the Java Naming and Directory Interface.
