Abstract

of


by

Ramyakanth Edupuganti

The increasing growth in the number of the computer science courses offered at the

universities and the enrollment of the students to the computer science courses, demands

a better way for students to submit assignments and an efficient way for the professors to

review and grade the programming assignments. The main objective of the “Online

Grading System” is to allow the students to submit the softcopy of the programming

assignments online and to provide an option for the professor to remotely access the

assignment files of students on the Linux server, compile and execute the programming

files, view the results of the programs, and grade an assignment of a student.

In this “Online Grading System” project, HTML and Javascript programming languages

are used for the front-end applications and JSP and Servlets are used for the server side

programming and ‘MySQL’ database for storing the database contents. “Online Grading

System” provides an efficient way for the professors to create courses, register students to

the “Online Grading System”, post assignment for the courses, and grade assignments

v

submitted by the students. For the students, the “Online Grading System” provides a way

to enroll for the courses, view the assignments posted by the corresponding professor,

submit assignments, and view grades. The Administrator of the “Online Grading

System”, can register the Professors to the online grading system and start a new

semester.

CHAPTER 1

INTRODUCTION

In this century, technology has drastically improved and computer science plays an

important role in the development of technology. Due to the increased career prospects in

the computer science field and interests among the hobbyist, there has been a tremendous

increase in the number of computer science courses offered at the universities and in the

enrollment of students in the computer science department.

Programming is one of the most important parts of learning computer science. Large

numbers of courses offered at the universities teach programming languages,

technologies, and other principles. Professors provide programming assignments to the

students to give them experience and knowledge about programming languages.

Programming assignments are currently submitted by the students by uploading the files

to a server. The professor can then login to the server, compile and execute the

programming files, and then grade the programming assignment. This process of

compiling, executing, and grading the programming assignments is currently done

manually which takes a considerable amount of time and effort by the professors.

An Online Grading System provides an efficient way of managing assignments by both

professors and students. Professors can create courses, post assignments, deadlines for

assignments, compile, execute, and grade the assignments submitted by the students.

Students can register for courses, view assignments, submit assignments, and check

grades.

2

The Online Grading System is developed using HTML and Javascript for front-end

applications, JSP and Servlets for the server side programming, and MySQL database for

storing database contents. The Online Grading System supports a Linux Operating

System.

CHAPTER 2 REQUIREMENT ANALYSIS

2.1 Problem Statement:

Programming assignments are currently uploaded to a server by the students. The

professor has to login to the server, manually compile and execute the programming files

submitted by the students, and then assign a grade to the student. The grade that is

assigned to the student is usually stored in an Excel worksheet. There is no advanced

consolidated system which can manage all of this features and maintain the records.

2.2 Objective of the Project:

The objective of the Online Grading System, is to provide a consolidated web system

which allows professors to a create course, post assignments, assign deadlines for

assignments, and grade the assignments submitted by the student. The Online Grading

System also allows the student to register for courses, view assignments submitted by the

professor, submit assignments, and check grades.

2.3 Assumptions and Dependencies:

It is assumed that the user has access to internet and a web browser.

4

2.4 Non Functional Requirements:

1. The Project should be developed using J2EE technologies.

2. The project should support Linux Operating System.

3. Database included should be MySQL database.

4. Assignment projects submitted by students can be C, C++ and Java files.

5. Assignment description files posted by Professors and/or Students should be

created using Rich Text Format Editor.

2.5 Functional Requirements:

1. Only Administrator can add professors and start new semester.

2. Professors can add and delete students to the online grading system.

3. Professors can add and delete courses to the online grading system.

4. Professors can post assignments, compile, execute, and grade the programming

assignments submitted by the students.

5. Students can enroll courses and drop courses.

6. Students can view assignments assigned by the professors.

7. Students can submit programming projects.

8. Students can check grades.

CHAPTER 3

ARCHITECTURE AND DESIGN SPECIFICATION

3.1 Architecture:

The Online Grading System is designed and developed using a 3-tier architecture. The 3-

tier architecture consists of a presentation layer, an application layer, and a database.

The presentation layer is the front-end of a web application that is used to provide a rich

user interface experience to the end user. The application layer is the middle layer of a

web application that is used to process all the requests sent by the user by using front-end

application. The database is used to store all the information required by the Online

Grading System.

Figure 3.1 Architecture

6

3.1.1 Presentation Layer:

The presentation layer is the part of the web application that is visible to the end user.

The presentation layer is used by the end user to interact with the web application and

send requests to process. In the Online Grading System, HTML and Javascript is used to

develop the presentation layer.

3.1.2 Application Layer:

The application layer is the middle layer of a web application. The application layer is

used to process the requests sent by end user using the presentation layer. The application

layer also works as a middle level layer to process transactions between the presentation

layer and the database. In the Online Grading System, JSP and Java servlets are used to

develop the application layer.

3.1.3 Database:

The database is the third and final layer of a web application. The database is used to

store and retrieve the user information when necessary. In the Online Grading System,

MySQL data is used to store and retrieve the user information.

3.2 Application Design:

The Online Grading System application consists of three types of users. They are

Administrator, Professors, and Students. Detailed user privileges are as follows:

7

3.2.1 Administrator:

1. Administrator has the highest privilege.

2. Administrator can add professors.

3. Administrator can add a semester at the start of a university academic semester.

3.2.2 Professors:

1. Professors can add students to the system.

2. Professors can delete a student from the system.

3. Professors can add a course to the system.

4. Professors can drop a course from the system.

5. Professors can post assignments and assign deadlines to the corresponding

assignment.

6. Professors can view the assignments submitted by the students.

7. Professors can compile and execute the programming assignments using the

Online Grading System.

8. Professors can view the results of the programming assignments.

9. Professors can assign grades for student assignments.

3.2.3 Students:

1. Students can register in the system.

2. Students can enroll for a course or drop a course.

3. Students can view the assignments posted by professors for enrolled courses.

8

4. Students can submit assignments before the deadlines.

5. Students can view the assignments.

CHAPTER 4

IMPLEMENTATION

This chapter provides an overview of implementation details of the Online Grading

System. The Online Grading System is developed using HTML, Javascript, Java Server

Pages, Java Servlets, and MySQL database.

4.1 Integrated Development Environment:

The Online Grading System is developed using Netbeans Integrated Development

Environment. Netbeans can be downloaded from https://netbeans.org/downloads/.

Netbeans contains an internal Apache Tomcat server, which can be used to host the web

application from the local machine as a localhost. New project can be created in Netbeans

by going into File -> New Project. Screenshot of the Netbeans IDE is show as below:

CHAPTER 6

FUTURE PROSPECTIVE WORK

The Online Grading System contains the necessary features to support the assignment

management system. For the future course of the project,

1. A tree structure can be implemented to better manage the files across different

semesters and years. This can also be used to add or delete a folder and

upload/download files so that other files besides assignments can be uploaded and

saved for a corresponding semester by the professors.

2. Currently the Online Grading System supports C, C++ and Java programming

assignments. In the future more programming languages can be supported.

3. Further enhancements to the Online Grading System such as approval method can

be implemented.
