Very much like the "Rdb Transparent Gateway to ODBC data" that is
(was) part of the "Database Integration" (DBI) kit, that is still
available unsupported from Oracle for Alpha.

That gateway (that had a standard Rdb SQL interface so it could
be called from any VMS language using the Rdb SQL precompiler, the
application did not now it was not accessing a real Rdb database)
connected to a Windows box where you can access any database (or
"data source") that had a ODBC driver.
