¢¢¢168 Bvis Car Hire Company: The Problem DescriptionThe management requires that every completed hire is recorded with the details of the customer, thedates of the beginning and end of hire, and the amount of the payment.There is a record kept for each hire class of vehicles: the daily, weekly, and monthly hire rates arerecorded. These rates vary from model to model according to the hire class.The garage keeps a record of the name, address and home telephone number of each mechanic; themanagement must keep track of the mechanics with the same name and telephone number. It is arequirement of the company that all mechanics hold a current driving license.You are to develop and implement a computer-based system to replace the current manual system. Thesystem should be paperless. Functions are to be provided for the following queries and updates.1. Register a new customer.2. Record that a particular car has been hired.3. Record that a particular car has been returned.4. Calculate the cost based on the daily hire rate.5. Display the appropriate details, and print out a receipt.6. Log a completed hire.7. Record a service for a particular car, together with the date of the service, the type of the service, andthe name of the mechanic responsible.8. Remove a customer.9. Add a new car to the fleet.10. Delete a car that is no longer in the hire fleet.11. Add a mechanic who has joined the company.12. Remove the details of a mechanic who has left the company.13. Determine if a particular car is due for a particular service.14. List the information (history) about all hires for a specified car.15. List the information (history) about all services that a specified car has had.Questions1. Characterise the Bvis Car Hire Company described above in terms of the five attributes of a complexsystem discussed in Chapter 3 of the course notes. Elaborate the problem description as necessary tosupport your analysis.2. Present the system functions according to the guidelines in Section 4.1 of the course notes.Report No. 259, July 2002UNU/IIST, P.O. Box 3058, Macau
Bvis Car Hire Company: The Problem Description 1693. Identify the essential use cases which cover and support the understanding of the required functionsin the problem description.4. Write an expanded version for each of these use cases.5. Draw a use case diagram for the use cases that you identified in the previous question to show therelationships between the actors and the use cases, and the relationships between the use cases.6. Using the guidelines, strategies, and notation discussed in Chapter 5 of the course notes, work throughthe problem statement and the use-case model that you have produced to identify classes (concepts),associations, and attributes in the application domain. You should give enough discussion to supportyour identification. Draw a conceptual model which includes, the classes, associations, and attributesthat you have identified.7. Use the techniques discussed in Chapter 6 of the course notes to identify the system operationsfrom the typical course of events of the use cases that you have produced. Draw a system sequencediagrams for the typical course of events of the use cases that you think most significant for thedevelopment of the system.8. Based on your use-case model and conceptual model that you have produced, write the contracts forthe system operations that you have identified in Question 2 of this worksheet. You may find thatyou need to refine or modify your use-case model and conceptual model while you are working onthis question.9. Based on the use-case model that you produced, the conceptula model and the contracts of the systemoperations that you defined, work out a design for the system. The design document should include(a) The collaboration diagrams which show the assignment of responsibilities to classes of objects.(b) Enough discussion about the use of the patterns in your assignment of responsibilities to classesof objects.(c) The design class diagrams which shows the methods/operations of classes.Again, you may find that you need to refine or modify your use-case model, conceptual model, andthe contracts of the system operations while you are working on this question.10. Following your collaboration diagrams, define Java definitions for at least the classes in your designclass diagrams.Report No. 259, July 2002UNU/IIST, P.O. Box 3058, Macau
