If there a way to protect against concurrent modifications of the same data base entry by two or more users?

It would be acceptable to show an error message to the user performing the second commit/save operation, but data should not be silently overwritten.

I think locking the entry is not an option, as a user might use the "Back" button or simply close his browser, leaving the lock for ever.
