An auto rental company wants to develop an automated system to handle car reservations, customer billing and car auctions. Usually a customer reserves a car, picks it up, and then returns it after a certain period of time. At the time of pick up, the customer has the option to buy or waive collision insurance. When the car is returned, the customer receives a bill and pays the specified amount. Note that mileage should be recorded both at time of pick up and on return, in order to bill the appropriate amount. In addition to renting out cars, every six months or so, the company auctions the cars that have over 20,000 miles. Draw a use case diagram to capture the requirements of the system to be developed. Include an abstract use case for capturing the common behavior among any two use cases. Extend the diagram to capture corporate billing, where corporate customers are not directly billed; rather, the corporations they work for are billed and payments are made sometime later.
