I am refactoring application into a 3-tier approach: UI, BIZ, DA. I am wondering, what would BIZ tier do when user wants to delete a row? I can't seem to find a logic for a code in the BIZ tier in this case. But I don't want to call a DA method ( that deletes a row) from UI tier because this is supposed to be a bad design.
I would appreciate any suggestion.
