This exam includes two modeling exercises. For the Auto Rental System (ARS) please create the following UML diagrams: 1. A Relational / Class diagram including attributes, PKs / FKs, associations / multiplicity between relations, and any advanced features. Data types and methods/roles/responsibilities are not required to be shown. 2. A Sequence diagram including basic and any advanced features. The ARS process to be modeled is a car return and billing for individual and corporate customers. Assume the car has accumulated over 20,000 miles upon its return and is put on auction to the highest bidder. Auto Rental System (ARS) An auto rental company wants to develop an automated system that can 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. Reservations for cars include the customer name, address, date and time of pick up and expected return, and auto model preference (sedan, convertible, SUV). At the time of pickup, the customer has the option to buy or waive collision insurance on the car. When the car is returned, the customer receives a bill and pays the specified amount. Regular corporate customers renting cars for their employees are not billed directly when the auto is returned; rather the company is billed on a quarterly basis on return of rentals. In addition to renting cars, every six months the auto rental company auctions the cars that have accumulated over 20,000 miles. There are separate auctions for individual vs. corporate customers. All auctions are final at which time the customer receives a bill and pays the specified amount
