The other thing to note is that RDO was intended to be a VB class wrapper
around ODBC and that DAO is best used with Microsquish JET (Access)
databases, but doesn't work very well with ODBC databases.  Also ADO (as far
as I have heard) right now works best with SQL Server, and is moving along
with Oracle but not with much else.
