That is, in fact, the approach taken in a product called Dataphor
(see www.alphora.com). They have implemented a "D"-language (called D4)
that translates into SQL and hence uses underlying SQLServer, Oracle
or DB2- DBMS'es as the engine.
It is, however, not a very easy mapping to do and you have to resort
to all sorts of unclean stuff to make it work...
