This system integrates functionalities such as user authentication, result storage, and retrieval mechanisms to ensure secure and efficient access to grades. Employing robust database management systems and encryption techniques enhances data security and confidentiality. Additionally, incorporating features like result notifications and analytics provides users with valuable insights and enhances user engagement. Continuous monitoring and updates to the platform ensure scalability and adaptability to evolving technological trends, ultimately fostering a seamless and satisfactory user experience.

ABSTRACT

In Nigerian Universities a lot of time is spent by students, faculty and lecturers in effecting result processes.

This project focuses on solving the problem by developing an application to solve the problem inherent to the delivery of examination information services in Nigerian universities using the University of Calabar as a case study. The MyResult Application is a web-based application intended to be accessible from the internet. This allows the application to be available to both mobile phone users and PC users who can access the internet from their devices. The MyResult system was developed using open source web technologies notably HTML, PHP and MySQL.

The MyResult system produced in this research work has functions that will enable students to check course results, view computed GPAs and log complaints with maximum ease.

The developed application was tested using the XAMP application suite and the test results show that the application works as expected.

CHAPTER ONE

GENERAL INTRODUCTION

1.1 Introduction

It seems quite a safe bet to assert that the Internet and mobile Communication have had a preponderant influence on the way the world relates today. On the other hand, education remains a sine qua non fact of life for the overwhelming majority of human society In Nigeria; the educational sector has experienced marked changes as a result of the introduction of internet-based services. In one case, results for the UTME (Universities Tertiary Matriculation Examination) are now processed and released within days of the examination being written, an ever-increasing number of universities are employing the Internet to deliver a widening range of information and support services, covering such areas as admissions, student registration, examination records, and distance learning.

This work is an attempt at delivering an online system capable of delivering examination results on demand, using the University of Calabar as case study. This application will also provide capability to assist students, lecturers and administrative personnel interact in resolving any result-related complaints.

This chapter introduces the work as an entity, discussing the issues which are fundamental to the work ab initio:

The problem scenarios which, prima facie, lend necessity to the work;
The modalities pertaining to the realization of the solution system;
The content and extent to which the work will be carried out;
Definitions of key terms relevant to the central theme of the work.

1.2 Statement of the Problem

The major problems regarding the delivery of examination information services in Nigerian universities include:

Delays in the release of results;
Errors inherent in handling and assessment of answer scripts;
Delays in marking answer scripts; and
Cumbersome response systems – where they exist – for handling result-related complaints.

1.3 Objectives of the Study

From the foregoing, the objectives of the study become quite clear – as a result, the study aims to achieve the following:

Conceptual design for a secure, accessible and user-friendly online examination results system for a university, using the University of Calabar, UNICAL, as case study;
Development of such a system to demonstrate its functionality, using the XAMP (cross-browser Apache/MySQL/PHP) web server framework;
Perform tests on the said system to assure functionality, accessibility and usability of the system.

1.4 Research Justification

Justification for engaging in this study can be drawn from the following reasons:

The need to demonstrate the effectiveness of employing mobile driven information systems as a viable complement to systems based on the regular Web, within the university information framework; and
The need to achieve a greater degree of responsiveness among stakeholders in the results system – students, lecturers and system administrators – enabling them collaborate effectively to resolve result-related complaints.

1.5 Research Methodology

In order to realize the objectives of this study, it is pertinent that, as in all matters of substance, strategy be employed in achieving set goals. The methodology employed in the course of this study is outlined thus:

Outline a set of requirements to be met by the system proposed;
Conceive and implement the design of the said system as a web based application, largely using UML, the Unified Modelling Language, along the lines of an object-oriented approach;
Development of the solution system using Adobe Dreamweaver CS5, a RAD (Rapid Application Development) IDE for creating Websites and applications.
Deployment of the solution system for testing: after the solution is developed, it will be uploaded onto a free web server for the purposes of demonstrating its functionality.
Beta testing on the hosted solution to confirm its conformity to the system requirement specifications earlier outlined;
Detailed reporting of the findings stated above, with deduced inferences, and noted grounds for future innovation.

1.6 Scope and Limitations of the Study

In the course of realizing this project, I shall take into account the consideration that all development and analysis regarding the project will be centered on internet standards and technology.

In full, the scope of the work is outlined thus:

The solution, as conceived and developed in this study, will focus on examinations for undergraduate courses only;
The questions delivered by the solution will be of two formats, viz, multiple-choice and subjective;
As conceived, the solution shall comprise of the following modules:
A result search application for students, based on the Internet, through which students and lecturers can search and view results, as well as interact regarding result-related complaints;
A back-end application, to be used by lecturers and administrators, for the management of essential information for the system, such as course allocations, course student lists
User authentication modules, which will employ unique modes of authentication to uniquely identify users, and maintain user state within the application.

In addition, a number of limitations exist which must be noted. These include:

The proprietary nature of the school portal will make it rather difficult to access the data schema used by it; hence, the data schemas employed by the proposed system will for the most part be theoretical in nature. However, this can be surmounted with adequate cooperation from relevant agencies within the University Management;
The time-critical nature of the study informs my use of prototype-based RAD to develop the proposed solution.

1.7 Definition of Terms

UML: Unified Modeling Language, the international standard for specifying, visualizing, constructing and documenting the artifacts of software systems.
User authentication: the process within the context of an Internet application wherein eligible users are granted clearance to enter – and use – the application;
User state: the full set of all user-specific program data within a program or Internet application.
Online result System: It is web based software that can process course registration and output results to the user.
Web application: see Internet application.
