I would like to design a database of bookshop. I would like to control the stock of shop. orders detail,,, customer record,,, supplier.....Beside this,,,, I would like to manage the stock as when i entered the products from supplier then the stock should be updated (add item in existing item). if i sell the item to customer, then the stock should also be updated (minus the quantity from existing item.)..
