It's implemented? Without transaction you have to provide a way of
telling people what failed and why and pass back the ID of created
objects. Transactions are less work. In theory it should be just:
1. Request received open transaction
2. Process commands
3. On error, abort else commit
I can imagine the indivudual bits of code don't know they're running
in a transaction.
Have a nice day,
