DB2 Universal Database users now have the power of distributed query across any DB2 family database or OLE DB source. This means that users and applications can use the DB2 Universal Database SQL syntax and APIs to access data that resides at heterogeneous data sources. With this functionality, users and applications have the capability of referencing multiple data sources in a single SQL statement. With Relational Connect, distributed queries can also include Oracle databases (see DB2 Relational Connect).
This is the first phase of the integration of DB2 DataJoiner into DB2 Universal Database. DataJoiner is IBM's middleware product for integrating heterogeneous data sources. See the Administration Guide: Planning and the Administration Guide: Implementation for more information.
