好吧,我有一张我老板做的桌子……它们是两张桌子……
first where products are going to be has
(table A)
idinvoice (since table B)
idpruduct
description (it is the name of product)
quantity
unitPrice
TotalPrice
another table (i am going to call it table B)
idinvoice
date
deadline
type
idclient
saler (i consider it is sooo bad)
street
transport
status
Total
为什么我认为它是坏的?
因为首先客户要选择产品(但它没有idinvoice)我从来没有做过这样的事情,只在Windows窗体上,但我从来没有建立过在线点销售,
你认为我必须有几张桌子?(什么栏目)
