All,

Just wanted to open a discussion regarding MVC architecture and transaction support.

Basically, which piece ideally handles doing the COMMIT or ROLLBACK?

Does the answer change when dealing with green-screen programs where the view & controller are
combined into a single program?

My stance is that the COMMIT / ROLLBACK belongs in the model portion. The controller will be calling
a procedure that either commits or rolls back as required.

However, another developer prefers having the controller do the commit / rollback. Besides "having
been bit in that past" by procedures that do their own commit/rollback, his argument is that you
should avoid side effects in a procedure. I can see his point if for instance, you've got a current
procedure that does one standalone function. Then in the future, you come up with a new function,
which wants to reuse the prior function as part of a larger transaction.

The only thing I can think of would be to have a extra parm passed in to the function which tells it
if it is a standalone transaction or part of a larger one.

Thoughts, comments, arguments for or against?

Thanks,

Charles Wilt
