My opinion is that people are used to hitting the back button while browsing normal pages, but are also used to not being able to hit the back button while using web software. Maybe that's just me as a power user, I'm not sure what the average user experiences. Lots of users these days though use webmail, or other web based software in which the idea of hitting the back button doesn't really make sense.

I'd say you do whatever you think works better. I don't completely understand how it would work though, as hitting the back button will not undo any database changes that may have been made.
