Ok, of course our application must ensure that each user session commit data and see data with coherence.

But in wich way I can management savepoints? Is there some documentation about it?
When I use TOracleDataset I see a call to savepoint DOA__LOCKPOINT, and when I call ApplyUpdates too (DOA_APPLYPOINT).
I have to redefines these behavior when using ThreadSafe session or they works good?
