We are looking at using an RDBMS, such as Oracle, with OLE2 on the client. The bridge between the client and server is an ORB. So far Orbix by Iona is the choice. Informal benchmarking indicates that Orbix is quite fast.

We like Orbix because it provides a clen interface/bridge to our server objects through OLE2. We feel that once we develop our server objects, we can quickly respond to user requests for new client applications or changes to existing applications since the client is so thin.
By the way, I do not work for or in any way am I associated with Iona. This is just my opinion.
