i used my Google-Fu on "linked server 4D database" and "4d database ODBC driver", thinking that should get what you need
this link seemed to have an example of creating a linked server, but the poster said it's untested:
http://permalink.gmane.org/gmane.comp.lang.inug-4d.tech/101605
but i didn't find anything recent at all, and no true examples, just lots of posts requesting a linked server, but none with a working example.
