Use Case: Rent Copies
Actors: Clerk and Manager
Goal: To rent out a copy of a rentable item.
Overview: The customer comes in and selects something to rent. The clerk looks up
the item and if it is available for rent. If it is, the clerk enters the customer’s phone
number (for returning customers) or complete information (name, address, and
phone number, for new customers), and the ID of the item(s) to be rented or rentto-owned. The system then displays the charge and the due date or the date on
which the next payment is due for each item, and the total charge owed. The clerk
collects this amount from the customer, and the customer leaves.
