Auto Rental System Requirements Specification Statement: The Auto Rental System (AR System) is able to handle car reservations, customer billing, and car auctions. When a customer reserves a car, he/she can use online reservation to make a general reservation. The system must be able to look for the matched available car in Car Data Base and form a new reservation in Reservation Data Base. If the customer makes reservation in person, the assistant of rental company is able to access the customer data base, car data base, and reservation data base internally and make a reservation for the customer. After the each reservation is made, the corresponding car will be shown as unavailable in car database. When the customer picks up the car, the assistant can access the customer’s reservation record with the reservation number customer provided. The customer and the assistant are able to complete the rental lease using the system. After the completion of the rental lease, the new lease will be recorded in customer data base. (Each lease is directly related to customer’s billing information.) Then the system will print out a car rental card (internally used in the company). The customer obtains the key of the car from Technician of the rental company with the car rental card. After the customer checks the status of the car and accept the car, the Technician is able to use AR system to update the car data base that the corresponding car is “ in-rental” status. Then the corresponding rental lease status is updated as “1/3 completion” . When the customer returns the car, the technician will check the status of the car. A damage report and a miles report will be made with the AR system. The damage report will be directly related to car database and customer’s billing information. And the miles report will update the car database. If the car has accumulated over 20,000 miles, it will be listed to the “Car Auction List” and deleted in “available car list” . And the corresponding rental lease status is updated as “2/3 completion” . AR system is able to print out a bill. If the customer pays the bill, the transaction will be completed immediately. After the customer pays the bill, the “ rental lease status” is updated as “Full completion” . If the customer’s corporation pays the bill for the customer, the system will send the bill to the corporation where customer works for. The “ rental lease status” will not be “Full completion” until the rental company receive the payments.
