The main components of the system are Customer, Web User, Account, Shopping Cart, Product, Order, Payment, etc. Each customer has a unique id and is linked to exactly one account. Account owns shopping cart and orders. The customer could register as a web user to be able to buy items online. The customer is not required to be a web user because purchases could also be made by phone or by ordering from catalogues. The web user has a login name which also serves as a unique id. Web users could be in several states (new, active, temporarily blocked, or banned) and be linked to a shopping cart. Account owns customer orders. Customers may have no orders or put many orders simultaneously. Customer orders are sorted and unique. Each order could refer to several payments. Every payment has a unique id and is related to exactly one account. Each order has current order status. Both order and the shopping cart have line items linked to a specific product. Each line item is related to exactly one product. A product can be associated with many line items or no item at all.
