Help me please !!

I have some people in my company that want to develop a software that runs actually on Access in Oracle. The problem is that they know Access, not Oracle. They just want to link the Oracle tables in Access, and develop clioent software with Access.

So they will develop their bull****, and I see the problems coming :

- Data modifications without COMMIT or ROLLBACK in jobs, will cause data inconsistency
- Performance problems, because they will use the client PC and Access to make loops in the tables and modify data... rather than using stored procedures, etc..
- Timeout problems with ODBC driver ?
- Cannot use PL/SQL within Access
- SQL standard differs from Oracle to Access ?

I'm not sure with all the points, be I have a meeting this afternoon to convince them that's not a good idea. Please con you confirm my idea ? Do you see any upcoming problems with this solution ??
