CHAPTER 2: SOFTWARE REQUIREMENT SPECIFICATION

2.1 INTRODUCTION

2.1.1 BACKGROUND

What is E-Learning System?

E-learning is commonly referred to the intentional use of networked information and

communications technology in teaching and learning. A number of other terms are also

used to describe this mode of teaching and learning. They include online learning, virtual

learning, distributed learning, network and web- based learning. Fundamentally, they all

refer to educational processes that utilize information and communications technology to

mediate asynchronous as well as synchronous learning and teaching activities. On closer

scrutiny, however, it will be clear that these labels refer to slightly different educational

processes and as such they cannot be used synonymously with the term e-learning.

The term e-learning comprises a lot more than online learning, virtual learning, distributed

learning, networked or web-based learning. As the letter “e” in e-learning stands for the word

“electronic”, e-learning would incorporate all educational activities that are carried out by

individuals or groups working online or offline, and synchronously or asynchronously via

networked or standalone computers and other electronic devices.

E-LEARNING SYSTEM

2.1.2 OVERALL DESCRIPTION

E-learning is a form of distance learning where education and training courses are delivered

using computer technology. Typically, this means that courses are delivered either via the

Internet, or on computer networks (linked computers). With the increased availability of PCs

and Internet access, e-learning is becoming more and more popular.

E-Learning is a web application uses JSP. The database is MySQL. This online application

enables the end users to register online, select the subject, read the tutorial and appear for the

exam online. The results of the exams are also declared just after taking the test. Marks of the

candidate are displayed just after submitting of an exam. The correct answers for the

questions are displayed after the exam. The date of the registration, date of exam, number of

attempts, test result etc. is stored in the database.

Contemporary trends in e-learning

The growing interest in e-learning seems to be coming from several directions. These

include organizations that have traditionally offered distance education programs either in a

single, dual or mixed mode setting. They see the incorporation of online learning in their

repertoire as a logical extension of their distance education activities. The corporate sector, on

the other hand, is interested in e-learning as a way of rationalizing the costs of their in-house

staff training activities. E-learning is of interest to residential campus-based educational

organizations as well. They see e-learning as a way of improving access to their programs

and also as a way of tapping into growing niche markets.

The growth of e-learning is directly related to the increasing access to information and

communications technology, as well it‟s decreasing cost. The capacity of information and

communications technology to support multimedia resource-based learning and teaching is

also relevant to the growing interest in e-learning. Growing numbers of teachers are

increasingly using information and communications technology to support their teaching.

Educational organizations to see advantages in making their programs accessible via a

range of distributed locations, including on- campus, home and other community learning or

resource centres.

Understanding of existing system

Shows educators and trainers how to adapt teaching methods and materials to make use of the

Internet. Including a framework showing how to apply Internet technology progressively as

skills and confidence grow, the project demonstrates the route from adapting materials to

developing a virtual course.

Nowadays, when people are not having time to visit an institute. Therefore, the software is

designed to provide the education through Internet. The project “E – LEARNING” helps the

common world in any field they are to get the knowledge what they want even sitting at there

places. This helps them to spare time in their busy schedule and save their time during

transportation

E-LEARNING SYSTEM

2.4 NON-FUNCTIONAL REQUIREMNTS

Flexibility:

A key attribute of the system is its ability to enable flexible access to information and

resources. Flexible access of resource means E-Learning System can be used in any operating

system, any browser with some basic requirements. The server for this system is running

24*7 all the time. A person across the globe can use this system.

Security Requirements:

Only authorized person can view and modify confidential details. User can only activate

his/her account after visiting activation link sent to his/her email account, so there is no

chance of having a fake email id. One user cannot access other user‟s account. Faculty can

only upload material after admin approve it. User has to enter his old password for changing

his password. User can only recover his/her password after entering his/her email id which

he/she has entered at the time of registration.

Scalability Requirements:

The system must be scalable enough to be able to add any additional functionality even after

the project is developed once.

Usability Requirements:

The application is user-friendly and provides ease of access for users. There are set of FAQs

set by Admin of the system which guides the user, if user find some trouble in accessing a

system.

Extensibility

The system should be designed to be extensible to changes. A change might be a result of

either a change in the user requirements or upgrading of system. Addition of new modules

should be smooth and easy.

Performance Requirements

The system is to be used as a web application and targets users across the globe, so it is

expected to be robust i.e. up and running all the time.

Session Control

It refers to the practice of session removal and session retain while navigating through

various screens during user interaction. As access control is a prime need of the system, the

session should restrict access according to the privileges defined for the user. It provides a

mechanism in which if user‟s system crashes while performing an exam, user can continue

his/her exam from the failure state when system recovers from a failure.

E-LEARNING SYSTEM

2.5 FEASIBILITY STUDY

An important outcome of the preliminary investigation is the determination that the system is

feasible or not. The main aim of the feasibility study activity is to determine whether it would

be financially and technically feasible to develop a project .The feasibility study activity

involves the analysis of the problem and collection of all relevant information relating to the

product such as the different data items which would be input to the system, the processing

required to be carried out on these data, the output required to be produced by the system as

well as the various constraints on the behaviour of the system.

Three types of project feasibility have been considered:

Economic Feasibility

The system being developed is economic with respect to user‟s point of view. It is

cost effective in the sense that has eliminated the paper work & transportation cost

completely.

The system is also time effective because the marks calculations are automated and

result of the exam is generated in no time, the result obtained contains minimum

errors and are highly accurate as the data is required.

Technical Feasibility

The technical requirement for the system is economic and it does not use any

additional Hardware and software.

Behavioural Feasibility

The system working is quite easy to use and learn due to its simple but attractive

interface. User requires no special training for operating the system.

APPLIED AND TIMELINE OF THE PROJECT

3.1 SOFTWARE ENGINEERING PARADIGM

Waterfall Model

Figure 3.1 Waterfall Model

Waterfall Model is one of the most widely used Software Development Process. It is also

called as "Linear Sequential model" or the "classic life cycle" or iterative model. It is widely

used in the commercial development projects. It is called so because here, we move to next

phase (step) after getting input from previous phase, like in a waterfall, water flows down to from the upper steps.

Requirement Analysis

Design

Implementation

Testing

E-LEARNING SYSTEM

The detailed description of these phases is as follows:

Requirement analysis & Specification:

The system‟s services, constraints and goals are established by consultation

with admin, faculty and user. They are then defined in detail and serve as a system

specification. Here all the requirements of the E-Learning System from the user are

clearly gathered by me which will be used by the other software phases.

System must fulfil functional requirements specified by user. These are

functional and non-functional requirements. Functional requirements for this system

are as follows: online exam, video conference, tutorial download, and non-functional

requirements include security requirements, flexibility, performance, session control.

Design:

Development of a plan. How the requirements can be implemented? This

process heavily depends on the chosen modelling techniques like ER,Data Flow,

Sequence, Use cases and the programming language as jsp, servlet and environment

characteristics such as hardware and software.to be used. It establishes overall system

architecture. Determines the software framework of a system to meet the specific

requirements.

Implementation:

Development of program text that can be compiled into executable code

including testing on the module level. Developers implement the functionality of the

E-learning System which will be tested in the testing phase.

Testing:

Testing the software product against its requirements. The individual program

unit or programs are integrated and tested as a complete system to ensure that the

software requirements have been met. After testing, the software system is delivered

to the customer. Implemented E-learning System is now tested against user‟s

requirements so that it is delivered to the intended user.
