UESTION ONE CASE SCENARIO: All first-time Customers of a Vehicle Rental Company must register with the system over the Internet. For registration, the Customer provides the following information: name and address, national ID number, driving permit number and an email address. Once registered, the system generates a unique Customer Account Number which will identify the Customer for the life of the system, therefore the Customer is given the account number to be used to log into the system in the future. This account number and registration information is stored in the Customer Database. Customers reserve vehicles over the internet by providing rental information such as the start and end date of the rental period. The Customer is then sent a Claim Ticket with a Claim Ticket Number to be printed, within seconds. The Claim Ticket Number and rental information is recorded in the Reservation Log. In order to collect the vehicle, the Customer provides the Attendant at office with the Claim Ticket Number, which the Attendant uses to query the Reservation Log to verify that the reservation is legitimate. The Customer then provides supporting documents to confirm his/her identity (name, address, national ID number, driving permit number). The new system automatically interfaces with a module of the Election and Boundaries Commission System to authenticate the national identification number. The new system also automatically interfaces with the National Transportation System to authenticate the driving permit number. If documents, identification card and driving permit number cannot be confirmed, the customer is denied the service. Once all documentation is verified, the attendant uses the system to select a vehicle for the Customer from a database of available vehicles. A particular vehicle is assigned to the Customer and the Vehicle File is updated to reflect that the particular vehicle is no longer available for rental. The vehicle is then located in the parking lot and the Attendant records the mileage for the vehicle. The rental payment is calculated together with the insurance and a refundable deposit amount. The system prints an invoice for the customer. The rental cost and charges are recorded in the Reservation Log. When the Customer pays the invoice amount and receives a payment receipt, the vehicle is delivered to the Customer. a) Draw a Context Diagram of the proposed system from the perspective of the vehicle rental process.
