Design and Implementation of Computerized Auto (Car) Leasing Information System

Design and Implementation of Computerized Auto (Car) Leasing Information System


Auto (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 the 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. It is here the computer system comes into play for its augmentation with the human effort at Marlum construction company Enugu will definitely provide an efficient system tat will monitor the model and quantity of cars in stock for lease. This will go a long way to provide an efficient leasing service by Marlum construction company and will certainly encourage other firms who are into car hire services to expand into car leasing operations.

The history of resources auto (car) leasing in Nigeria is a short one but the trend is growing as more organizations get into the provision of this services and strive to be ahead of completions. This car leasing is 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 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 save for ages before buying one. More over there exist a wide range of cars people can lease for different purpose. There are cars for inter city and business travels. The cars for research students and holiday makers. 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 cooperate organization. It has its main office at Emene in Enugu.


The actual problem Marlum Construction Company is facing the non-existence of an automated system that will show on prompt the available cars for lease. its leasing cost for minimum duration of one month.

This has made it difficult for clients to know the brand of cars available and the ones leased out and time they are due for return. It has impeded the rate of business, for most customers want an on the spot information so as to enable then make decision.


The principal purpose of this study is to develop an automated system that will list on prompt all cars available for lease, it’s leasing cost for a minimum time period of one month as well as keeping track record of all leased cars and when to return them to the company Marlum construction company.


The reason for embanking on this study is to overcame the short coming of the existing manual leasing method .it will achieve it by providing as follows.

(1) A system that will give customers all models and brand of cars available for lease and their cost of leasing it for a period of one month.

(2) A system that will keep track of all leased cars and the time due for return.

(3) An efficient system that is reliable and can aid in management decision making.


The scope of this research work still remains the leasing section of Marlum Construction Company.

This research work coves specifically only leasing of cars to companies. All other leasing activities concerning machines and other heavy-duty equipment are not concerned.


(1) It is assumed that there is constant power supply at Marlum Construction Company.

(2) It is assumed that an automated system will make customer’s take prompt decisions as regards their needs.

(3) That all users of the system are computer and appreciate the reliability of computers to execute instructions accurately.

(4) That all leased duration is counted in months with one month as the minimum leased duration.
