A WEB BASED EXAM-MANAGEMENT SYSTEM

1. Introduction

A Web-Based Exam-Management System is the System which can be utilized to conduct th

examinations in the college. It is integrated to conduct the test to evaluate student skills in a particular subjec

during the semester (or) after completion of the semester, to conduct the any technical (or)aptitude test (or

any quiz competition to the students in such situations the tool is our project i.e. A Web-Based Exam

Management System . This software is efficient in order to conduct the examination & evaluation is fas

quick and reliable result.

This software is integrated up to the college level. Every college can be use this software for the purpose o

the conducting student examinations theory & Online with the services of web-Technology.

Here an administrator is there in order to maintain all the students and faculty details.

The main purpose of this software is to reduce the effort to the examination branch in any college in

conducting the examination to students. The accuracy in evaluating the answer papers and gives the result

in short time through on-line and generating the question paper sets to conduct the theory exams to maintain

the secrecy.The question papers will be maintained by the administrator.

2.ANALYSIS

2.a.Example:

The main application of the automation of the online student examination system is th

educational system. The following is the examples of the automation of web_based exam managemen

system. The main usage of this system is to conduct online examination and theoy papers sets generation.

Registration of students

Registration of faculties

Syllabus Management

Assign faculties to subjects

Faculties sets question papers for theory and Online.

Question Papers maintenance of Administrator

Students appeared to Online Exam

Students Reports generation

The above all are the different modules in this system now we can explain the process of each of themseparately.

2.b.Process:

Registration of students:

By using this module administrator register the entire students in the college ,the details should hav

modifiability ,removable and can be viewed by the administrator. These persons only have an eligibility t

write the Online examination.

Registration of faculties:

By using this module administrator register the entire students in the college ,the details should hav

modifiability ,removable and can be viewed by the administrator. These persons only have an eligibility t

write the online examination.

Syllabus Management:

Administrator can set the entire syllabus i.e subjects related to class, branch wise for that particula

year. Syllabus can be modify ,delete and can be viewed by administrator.

Assign faculties to subjects:

In this module administrator assign faculties to subjects according to syllabus.

Faculties sets question papers:

Through this module faculty login by giving their id and password and then he will set the question

paper models for theory and online after giving the model then the question papers will be set by th

correspondent Faculties.

Question Papers maintenance of Administrator:

In this module all the question papers theory and online will be maintained by the Administrato

Papers can bes viewed,removed by the Admin.Students login by giving their id and password and then the

will write the online exam with in the time allocated by the faculty who gives the question paper.

Student appeared to online exam:


4/28

Page 4

By using this module students login by giving their id and password and then they will write th

exam within the time allocated by the faculty who given the question paper.

But the students who already appeared to that particular exam they will get error message.

Students Reports generation:

In this module Admin maintain the details of the results of the students who appeared to the onlin

exams. All the students have department, class, branch wise reports will be generated.

3. DATABASE DESIGN

3. a.1 :Database Design

E-R diagrams:

In this database design we mainly explain about the E-R diagrams. That means that entit

relation diagrams. Here we are explain about the all terms entity, object and relation. In this system w

are mainly having student, faculty ,syllabus, exam entities . We are having the three main relation

among them. Here every entity having some properties that are called objects. In this system we ar

mainly discuss about three E-R diagrams that are

Faculties set the question paper.

Students write the examination.

3.a.1.1 E-R diagram for Faculty sets the question paper:

The following diagram explains about the relationship between the faculty and sets the questio

paper on login by his id and password for the particular subjects which are assigned to him by administrato

Here faculty having fid,name,pwd,eid,phno and the qp having sub, nqa , qpcode and setqp has fid, tim

andmarks as attributes.

3.a.1.2. E-R diagram for Student writes the Examination

The following diagram explains about the relationship between the student and question pape

.when student writes the exam there exists a relation writes. Here student having the properties lik

sid,name,password,eid,phno,class,semister and question paper having the properties qpcode ,name ,su

,contact no and email then similarly writes having the properties subject,qpcode.

3.a.2.Data Base Tables

In this project we have mainly 8 perminent tables and 2 temporary tables those will created at th

time of writing the exam of a particular student and droped after the completion of the examof student.

Tables are mentioned in the following.

3.a.2.1.Table: student_profile.

3.b. DIAGRAMS:

3.b.1.Class Diagram:

Class diagrams are widely used to describe the types of objects in a system and their relationships. Clas

diagrams model class structure and contents using design elements such as classes, packages and objects

Class diagrams describe three different perspectives when designing a system, conceptual, specification, an

implementation. These perspectives become evident as the diagram is created and help solidify the design

This Diagram Show the relationship between tables There are 11 Tables in this Diagram

3.b.2.Use Case Diagram:

A use case diagram in the Unified Modeling Language (UML) is a type of behavioral diagram defined b

and created from a Use-case analysis. Its purpose is to present a graphical overview of the functionalit

provided by a system in terms of actors, their goals , and any dependencies between those use cases.

3.b.3.Sequence Diagram:

Sequence diagrams belong to a group of UML diagrams called Interaction Diagrams. Sequenc

diagrams describe how objects interact over the course of time through an exchange of messages. A singl

sequence diagram often represents the flow of events for a single use case.

Instance:

An instance of a class shows a sample configuration of an object. On the sequence diagram, each instanc

has a lifeline box underneath it showing it's existence over a period of time.

Actor: An actor is anything outside the system that interacts with the system. It could be a user or anothe

system.

Message: The message indicates communication between objects. The order of messages from top t

bottom on your diagram should be the order in which the messages occur.

Sequence diagrams: In this Diagram there are eight Object Interaction to other Objects

3.b.4.ACTIVITY DIAGRAM:

Activity diagrams describe the workflow behavior of a system. Activity diagrams are similar tostat

diagramsbecause activities are the state of doing something. The diagrams describe the state of activities b

showing the sequence of activities performed. Activity diagrams can show activities that are conditional o

parallel.

Activity diagrams should be used in conjunction with other modeling techniques such as interactio

diagramsandstate diagrams. The main reason to use activity diagrams is to model the workflow behind th

system being designed. Activity Diagrams are also useful for: analyzing a use case by describing wha

actions need to take place and when they should occur; describing a complicated sequential algorithm; an

modeling applications with parallel processes.

5.Expected Conclusion:

In this module I concluded that the basi designes of the front ends of the project will be mentione

and also the database design will be mentioned.Mainly Administator is responsible to register,update and delete of both faculties and students.The Syllabu

will bemaintained by the Administrator.Faculty can Login with his/her Id and Password to set the Question Paper.Finally student can login to writthe exam..
