1.9 IBM WebSphere Federation Server and WebSphere Replication Server
IBM WebSphere Federation Server provides federated support by making remote data sources from IBM or different vendors appear as if they were part of the same database. The Federation server uses wrappers to communicate with and retrieve data from those other data sources; it encapsulates any conversions required from the source database and presents them to the target database as tables.
IBM WebSphere Replication Server provides replication support from one data server to another, even if they are not part of the IBM family. Replication Server includes both Q-replication and SQL replication (SQL replication is free with DB2 Enterprise).
IBM WebSphere Federation and Replication server software were formerly called WebSphere Information Integrator.
