The following list gives a brief description of each OLAP bean that provides data support for the presentation beans and query customizers:
Query object -- Represents the structured definition of a multidimensional query
QueryManager bean -- Provides services and support for one or more Query objects that reference a single logical data store
Connection -- Interprets the contents of an underlying metadata store (such as, a database or a BI Beans Catalog) and delivers the translated contents to its MetadataManager
MetadataManager -- Provides consolidated metadata access to the other OLAP beans from one or more data store connections (for a database or a BI Beans Catalog)
