A named SQL (Structured Query Language) query that simplifies access to one or more heterogeneous data sources. An information object retrieves data using database tables and views, stored procedures, and ODA data source queries as well as other information objects. A data modeler writes the query in Actuate SQL. The Integration service generates a native query for each data source and retrieves the data. A report developer or business user who uses the information object as a data source in BIRT Designer Professional or BIRT Studio does not require detailed knowledge of the underlying data sources.
