DESIGN AND IMPLEMENTATION OF COMPUTERIZED CAR LEASING INFORMATION SYSTEM
Car leasing has contributed to the growth of many industries in Nigeria. In dead companies who have short term contracts to execute find it cost-ineffective to purchase their own cars for a short duration. As a matter of fact, they depend on car leasing companies like Marlum Company the case study to lease cars to them throughout the duration of their contracts. But one factor remains indispensable; it is the manner in which the leasing services are operated most especially concerning efficiency.

The history of resources (car) leasing in Nigeria is a short one but the trend is growing as more organizations get into the provision of these services and strive to be ahead of completions. This car leasing is a gaming ground in Nigeria due to the fact that a lot of people cannot afford to buy their own cars.
The fall of Naira has resulted in the up shoot of prices of vehicles as can be seen in 1993 when the cost a luxury bus was 3 million Naira but in 1995 it came to 17 million Naira. Owing to the price increase, people prefer to lease cars rather than save for ages before buying one. Moreover there exist a wide range of cars people can lease for a different purpose.
There are cars for inter-city and business travels. Their cars for research students and holidaymakers. There are trucks for conveying heavy-duty machinery and long vehicles for goods. Marlum Construction Company is one organization that such services to individuals and cooperates with the organization. It has its main office at Emene in Enugu.

A lot has been written about the subject of web-based car leasing service all aiming at offering a credible service that can be accessed by customers at any time irrespective of the terminal or location. This chapter provides the literature review that is related to what will be developed later. This chapter comprises two sections: The first section reviews the method, equipment, and technology used.
The second section reviews the existing similar systems. References are made to books, articles, journals, magazines, conference papers, thesis, and also sources from the Internet.
MANAGEMENT INFORMATION SYSTEM
The rapid growth of interactive Internet services has led to constantly increasing Web sites (Berners-Lee, et al; 1992). We have also experienced an increase in their functionality, which, in turn, makes them more complicated to use. Thus, a useful web application should be based on traditional graphical user interface design which relies on menu selection and navigation.
But these interfaces require a considerable cognitive overhead. This may be tolerable to frequent users, but will in many cases deter casual users, especially those who are not yet used to computers (Nielsen, 1993). Management Information System is a system or process that provides information needed to manage organizations efficiently and effectively. Management information systems involve three primary resources namely: technology, information, and people.
It is important to recognize that while all three resources are key components when studying management information systems, the most important resource is people… (Scroll down for the link to get the Complete Project Material)

SYSTEM ANALYSIS AND METHODOLOGY
This chapter provides the method and approach which have been used for the system development. A detailed explanation of each phase in developing this project will be discussed. A methodology is important for managing and controlling research in order to achieve the specified objectives within a given time. In order to complete this research, there are some major phases involved.
Each phase involved in this project has significance in achieving the objectives of the project. This project begins with the knowledge acquisition phase and finished with the documentation of the result. As mentioned in the objective of this project, the data matching technique is applied to provide car recommendation service to the users.
Analysis of Traditional Car Leasing Service
Marlum Construction Company Car Leasing service operates a manual form of car leasing service. Under this system of operation, a customer places a call to the car operator and makes a reservation or he goes to the park to rent a car. Little or no records are kept and the customer may make a poor reservation choice because he cannot see through a phone call the car he is reserving.
Problems of the Existing System
- During reservation, a customer reserves a vehicle via phone call, or he/she is expected to go to the organization for reservation. There are many inconsistencies associated with such a method… (Scroll down for the link to get the Complete Project Material)
SYSTEMS DESIGN DIAGRAMS/ANALYSIS MODEL
This section presents the use case diagrams and description tables, activity, and sequence diagram representation of the proposed system.
- Use-Case Diagram
Use case diagram at its simplest is a representation of a user’s interaction with the system and depicting the specifications of a use-case. A use case diagram can portray the different types of users of a system and the case and will often be accompanied by other types of diagrams as well

SYSTEM IMPLEMENTATION, TESTING, AND DOCUMENTATION
System Implementation Requirement
The implementation of a system entails all those processes undertaken in the conversion of the old system to the new system. It begins from testing and debugging of the program to ensuring the elimination of potential problems users may face in the future. The process involves coding the instructions in a programming language of choice, testing the system, training the user on how to use it, and so on.
The overall system is very user-friendly; that is, it is designed so that any level of user can easily use it without having any sort of problem. To implement any system design into a computer program the most important consideration is first and foremost the programming language to be used for implementation.
Because it can be a major factor in determining the cost, complexity, user – operability and that which can be used for a wide array of programming functions. Some are more suited for writing certain types of the program than the others, based on their functionality or on criteria set by the programmer.
The choices of programming language for this project are:
- HTML (Hypertext Makeup Language)
- MYSQL (MY-Structure Query Language)
- PHP (Hypertext Pre-Processor)
- CSS (Cascading Style Sheet)

DATABASE DESIGN SPECIFICATIONS
The database management system used as the backend for the design and development of the system is MySQL. The database management system was used to create different database schema objects that store, retrieve, and manipulate the data in different dimensions for the automated system.
The major schema objects created in the database are database tables that are used to store the data for the application. The database tables were fully accessed using PHP (Hypertext Pre-Processor) connection from the application program interface (API) to the backend, which is the database server (MySQL Server). PHPMyAdmin provides an API for accessing database systems programmatically… (Scroll down for the link to get the Complete Project Material)
