Question 2: Domain Class Diagram

You are developing a new system for a catering company. The following scenario describes how anorder clerk will use the system to create an order for a catered event. In order for the customer toplace the order with the order clerk, they must have a copy of the catering menu so that they can give

the order clerk the item number for each food item they want to order. This menu is available onlineor in hard copy. The online ordering subsystem has not been developed yet so all orders have to beplaced by phone.

The items on the menu can be ordered by quantity, size or by quantity and size. For example, acustomer could order a cheese tray for 12 or 20 people; 3 5lb lasagnas; Garden salad for 20 people; or25 chocolate chip cookies, 15 peanut butter cookies, 8 white chocolate macadamia nut cookies. Theprices could be different for each type of cookie or cookies could be priced by the dozen no matter thekind. So the clerk has to be able to enter quantity, size or both, and the system has to be able tocalculate the correct extended price for each item.

When the order is finalized, the order clerk will print a copy and send it to the customer with aconfirmation letter giving the details of the order for the clients records.

Preconditions:The customer has a copy of the menu.The system is displaying the order screen.
