The data source of the BI Beans provides a JavaBean-compliant interface for creating and manipulating OLAP queries and for presenting the corresponding data to other components.
The data source of the BI Beans consists of the following two components:
QueryManager bean -- Provides services and support to queries that reference one logical database. The createQuery
factory method of the QueryManager instantiates a Query
object.
Query object -- Represents a structured definition of an individual query. A Query
object has state that can be persisted. The Query
object implements data retrieval interfaces through which it presents data to other components.
