Please see http://www.sapdb.org/7.4/sap_db_gnu.htm
SAP DB's interface is LGPL, so you can combine it
with closed source.

There are many people using this combination VB/ODBC.
The JDBC-driver is also applied in many projects.
Advantage here is, that it is a pure Java implementation,
that allows you to switch to other OS. In VB you
stick on Windows.

This is exactly what a German government department
(Bundeskartellamt) did some time ago. They developed in
VB/ODBC or ADO, respectivly, and SQL server. Due to
having the business logic in the DB they could quite
smoothly switch to SAP DB, where the client
software wasn't changed at all, besides changing
the connect string.
