RE: how to query across different platforms

["Eric Lehti" <elehti@xxxxxxxxxxxxxxxxxx>]

Or maybe DataPropagator?

IBM DB2 Replication (called DataPropagator on some platforms) is a
powerful, flexible facility for copying DB2 and/or Informix data from
one place to another. The IBM replication solution includes
transformation, joining, and the filtering of data. You can move data
between different platforms. You can distribute data to many different
places or consolidate data in one place from many different places. You
can exchange data between systems. 

The objective of this IBM Redbook is to provide you with detailed
information that you can use to install, configure, and implement
replication among the IBM database family - DB2 and Informix. The
Appendix C provides information about configuring federated access to
Informix, which can be used as a model for federated access to other
non-DB2 database, such as Oracle, MS SQL Server, Sybase, and more, using
DB2 Information Integrator V8. The redbook is organized so that each
chapter builds upon information from the previous chapter.
