Consider an online store system. There are three main players who involve in the system: storeOwner, customer, and supplier. A customer should be able to search the products in the store, add a copy of the products to his/her shopping cart, remove a copy of the products from his/her shopping cart, and check out. A supplier can add new products, update products information, and receive orders. A storeOwner sets the retail price of each product, and provides shipping service.
