I'd commit the data to the database as soon as the form is submitted, flagging it as "uncommitted" or whatever. Then when they hit the 'commit' button, you just clear that flag. That way there's no potential for data loss, even if the user's browser crashes, or they get called away on the phone and their session times out or whatever. They can log back in, and pull back up whatever they were working on.
