In its 9.7 release, InfoSphere Federation Server added a “JDBC wrapper.” This is an interface that lets the Federation Server access a database through that database’s JDBC driver. Someone asked me if I thought PostgreSQL could be accessed this way and then federated with DB2. I couldn’t see why not, so I gave it a try.
I found the official documentation in the Information Center to be a little light. However, a quick email to the friendly Federation Server team got me the guidance I needed. I was then easily able to federate DB2 and PostgreSQL tables. The SQL script at the end of this post reflects the information provided by the Federation Server team. It also ends with queries that join DB2 and PostgreSQL tables.
