BIT357 Car Rental Administration System Project - System Design

This project outlines the design and analysis of a Car Rental Administration System (CRAS) for Melbourne EZ Car Rentals. The project begins with an overview of the business, highlighting the need for a computerized system to manage car rentals effectively. The system's functionality includes booking management, customer and car information recording, handling car returns (including late and early returns), and online access to billing information. The project details the system's boundaries and functionality, followed by a use case diagram illustrating various use cases like login, checking availability, placing orders, payment processing, generating receipts, database management, recording car pickups, and order cancellation. Each use case is described in detail, covering actors, triggers, primary and alternative scenarios, exceptional scenarios, pre-conditions, post-conditions, and assumptions. Furthermore, a class diagram is provided to represent the system's data structure and relationships. The project concludes with a bibliography of relevant research papers. The student has provided a comprehensive overview of the design and analysis of a car rental administration system, including use case diagrams, class diagrams, and detailed descriptions of system functionality and processes. The project covers all aspects of the business, from customer booking to database management.

Overview of business
The considered business Melbourne EZ Car Rentals is the local company that offers
several vehicle rental services to the people. The main vehicles that are provided by the
organisation are the Sedan, SUV, MPV, luxury cars, Hatchback. In the present market,
because of the increase of the number of customer in the business, it has been analysed that
the business needs to implement an appropriate computerised system. The computerised
system that is being implemented in the organisation is the Car Rental Administration System
that support all the operations of the business easily.
Overview of system
The system would be able to provide the booking to the customers appropriately. This
system has been named as Car Rental Administration System. It is required from the system
to create new customer and the car information. When any customer places a booking request
either by calling or even walk-in, the organisation staff must be able to make the booking in
the system. The system would check the availability of the cars on the basis of the details that
are provided by the staff of the organisation.
Boundaries
 Provide car booking to the customer
 Cancellation of booking
 Retrieve information from database
Functionality
The system should also have the ability of cancelling any booking. Apart from this,
the CRAS must offer the main functionality of recording the customer details of any car
pickup and the return information. For any kind of car return, other than any normal return,

the implementation of two more methods would be done for handling the functionality, late
return and the early return. The system is to be made available online for allowing the
retrieval of the billing information of the customer from the online system anytime for any
future reference.
