ABSTRACT

A common challenge faced by universities is effective management of large amounts of data that are encountered in day-to-day operations. Access to these data requires various privileges and restrictions to cater for the various user categories. Traditional paper-based approach to managing these data, as practiced in many Nigerian universities, is costly, error-prone and ineffective. Existing solutions to this problem, where they exist, are ad hoc

or not comprehensive. In this thesis, we developed a web-based information (WeBAIS) capable of managing large bodies of data effectively for Nigerian universities. Evaluation feedback of WeBAIS received from the two pilot universities where it was deployed showed that WeBAIS met its design objectives. We believe WeBAIS will receive further favorable assessment as further research is conducted to polish its other modules.
