ABSTRACT

This project was concerned with the design of a Mobile Alert Information System

for Job Seekers in Nigeria. Based on the rate of unemployment in Nigeria, job seekers

continually seek for quicker and more effective ways of getting information about

available jobs. As a result more innovative channels of communication of vacancies

have long being sought by them.

Interviews and record inspection were used in order to carry out an in depth

investigation of the existing system. A feasibility study was carried out to assess the

workability, practicability and probable cost of developing the proposed system; which is

basically an SMS facility that gives job alerts.

The Structured System Analysis and Design Method (SSADM) was used to

model this system. The system includes an architecture, workflow and design of an alert

system that keeps job seekers updated about the latest vacancies. The information

system uses MySql as the backend database system, PHP, Notepad, Adobe Photoshop

and Microsoft hyper-terminal command program. The setup was done in Windows XP

operating system environment.

The system was evaluated to see its efficiency; and based on the users

response, it was considered easy to use, effective and efficient. The study

recommended that the system should incorporate a way in which users can register

their details via their mobile phones.
