Design And Implementation Of An Online Result Checker

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.

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

1.2 Problem Definition

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

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

1.3 Objective Of Study

From the foregoing, the objectives of the study become quite clear – as a result, the study aims to achieve the following: a. 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; b. Development of such a system to demonstrate its functionality, using the XAMP (cross-browser Apache/MySQL/PHP) web server framework; c. 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: a. The need to demonstrate the effectiveness of employing mobiledriven information systems as a viable complement to systems based on the regular Web, within the university information framework; and b. 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: a. Outline a set of requirements to be met by the system proposed; b. Conceive and implement the design of the said system as a webbased application, largely using UML, the Unified Modelling Language, along the lines of an object-oriented approach; c. Development of the solution system using Adobe Dreamweaver CS5, a RAD (Rapid Application Development) IDE for creating Websites and applications. d. 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. e. Beta testing on the hosted solution to confirm its conformity to the system requirement specifications earlier outlined; f. 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:

  1. The solution, as conceived and developed in this study, will focus on examinations for undergraduate courses only;
  2. The questions delivered by the solution will be of two formats, viz, multiple-choice and subjective;
  3. 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:

  1. 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;
  2. The time-critical nature of the study informs my use of prototype-based RAD to develop the proposed solution.

Summary, Recommendations and Conclusion

5.1 Summary

This project has simply been about designing an online result portal using the University of Calabar as a case study. The advantages of online result checking have been clearly stated which support the need for the MyResults web-based application.

In summary, the objective of the study was to demonstrate the viability of leveraging the strengths of online applications, such as portability, availability, affordability and mobility in the provision of real-time information, in this case students’ results information, to the stakeholders of the active system, i.e. students and the administrators. This simply means that students can check their results with minimum fuss, as they can access it with their computer systems.

5.2 Application of the Software to the Problem Domain

The utilization of the MyResult application can be shown in its usage and deployment.

Usage:

The system has two users; the student and the admin user. The students register for their courses for a particular session and the admin uploads the scores so that the student can view his/her scores and grades.

Deployment:

This can be in terms of hosting and how a user can have access to the application.

Hosting it requires registration of domain name and uploading of the application to the web server.

For the user to gain access to the system either with a computer system, an HTML-compliance browser is required.

5.3 Recommendations

A number of possibilities exist for the future exploration and development of the results portal system. These include:

  1. Development of a Web Service API (application programming interface) for the portal: This would provide ubiquity via the conversion of system data into formats such as JSON (JavaScript Object Notation) and XML (eXtensible Markup Language), which are easily adapted by third-party client interfaces (such as SMS-driven interfaces, widgets, as well as mobile and desktop applications) without affecting the security of the main application.
  2. Hosting the system on a virtual private network: The inherent advantage here is that the University can now isolate the system on a dedicated server which handles requests to the system separately from those going to the normal University website, optimizing its overall performance. In addition, the VPN ensures that the system is secure and accessible for its users on a 24-hour basis.
  3. Integration of SMS- and/or email-driven notification capability into the system, to enhance its overall interactivity with its user demographic.

5.4 Conclusion

As a result of this study, students and lecturers are presented with a system which would, if implemented, grant them ease in communications concerning results, with adequate capability for handling student complaints. Students can also take advantage of sitting in front of a desktop computer or laptop to access information related to their results.

5.5 Future Research

In additions to the recommendations in section 5.3, even more possibilities are there to explore. They are:

  1. Integration of SMS- and/or email-driven notification capability into the system, to enhance its overall interactivity with its user demographic.
  2. Currently the limitation in the system is that the courses and academic sessions are inbuilt, the system can be improved in future so that more courses and more sessions can be added dynamically by the administrator.
  3. Also for a more enhanced system the session can be divided into semesters, for example first and second semester.
