Implement a new IDataManager.  Most of the code in Connection is for
managing persistent objects, which wouldn't be relevant for you.

The IDataManager interface is documented relatively well.  You must also
arrange to have your implementation registered with the transaction
manager.  get_transaction().register(obj).
