we are doing a project on system. we have 5 different folders altogether. customer, product, order, inventory and invoice. so each of us have a menu bar and a toolbar and dialog boxes... when we tried to package them into a folders, examples, the codes for update. there are different function for it, like update inventory, update product, update order, update customer. so must we create an individual class for it or can we group them together.
