Data Interfaces that are Required by Presentation Beans

Four data retrieval and manipulation interfaces are essential for communication between the BI Beans presentation beans and their data source. These interfaces, which are contained in the package oracle.dss.util, are as follows:

If you use the BI Beans Query object as the data source for the presentation beans, then these data interfaces are implemented automatically for you. If you build your own data source, then you must provide implementations for the methods that you want to use in the DataSource, DataDirector, and DataAccess interfaces.
