Analysis of Proposed System

And

System requirements

CHAPTER - 2

2.1-System Analysis:

PROBLEMS IN EXITING SYSTEM

In the current system the main problem of resolving the queries of trainees is taking time delay

due to classes running in weekends or week days. If trainees have any problem regarding their

classes, have to wait for resolving their problem in the next classes. This problem breaks the

flow of study. Another problem is trainees only can communicate if they are at classes so its

create communication gap between trainees.

PROPOSED SYSTEM

We have analysis on the problems in exiting and designed a much simpler system to resolve

the problem.

In this system trainee can submit their question online and can get the solution easily at any

time. Trainees can create Group, join and communicate each other by sending message and

resolve their problem online. Moderator can upload article and Trainees can download article.

To achieve these objectives, Tech Mentro has planned to develop a web application named

etutes.in. etutes.in shall have following functionality:

Students can use etutes for training, submitting their questions, reading answers of posted queries, search topic and enhancing their skills.

Online courses of various technologies shall be introduced by Tech Mentro using etutes.

Online upload and download of article.

Analysis is a detailed study of the various operations performed by a system and their relation

within and outside the system. A key question is what must be done to solve the problem.

One aspect of the analysis defining the boundaries of the system and determining whether or

not a candidate system should consider other related system. During analysis data are collected

on the available files decision points and transaction handled by the parent system. Some

logical system models and tools are used in the analysis. Data flow diagrams, interviews,

onsite observation and questionnaires are examples, the interviews commonly used in analysis.

It requires special skill and sensitivity to the subject being interview bias in data collection and

interpretation can be problem.

6

System Planning and the Initial Investigation:

The most critical phase of managing system projects is planning to launch a system

investigation, we need plan detailing the steps to be taken, the people to be questioned and they

outcome expected. The initial investigation has the objective of determining whether the users

request has potential merit. The major steps are defining user requirements. When the initial

investigations completed. The user receives a proposal summarizing the finding the

recommendation of the analyst.

Information Gathering:

A key part of feasibility analysis is gathering information about the present system. The analyst

knows what information to gather, where to find it, how to collect it and what to make of it.

The proper use of tools for gathering information is the key to successful analysis.

The tools are the traditional interview, questionnaire, and on-site observation. We need to

know, for example how to structure an interview, what makes up a questionnaire, and what to

look for on-site observations. These tools when learned help analysis assess the effectiveness

of the present system and provide the ground work for recommending a candidate system.

Introduction to Java

Java is a high-level, third-generation programming language like C, FORTRAN, Perl and many

others. It is a platform for distributed computing a development and run-time environment that

contains built-in support for the World Wide Web.

History of Java

Java development began at Sun Microsystems in 1991, the same year the World Wide Web was

conceived. Javas creator, James Gosling did not design java for the Internet. His Objective was to

create a common development environment for consumer electronic devices which was easily portable

from one device to another. This effort evolved into a language, code named Oak and later renamed

Java that retains much of the syntax and power of c++, but is simpler and more platform-independent.

Java Features

Some of the important features of Java are as follows:

Simplicity

Orientation

Platform Independence

Security

High Performance

Multi Threading

Dynamic linking.

Garbage Collection.

One of the most important features of Java is platform independence, which makes it famous

and suitable language for World Wide Web.

Why Java is Platform Independent?

Java is Platform Independent because of Java Virtual Machine (JVM).

Java Virtual Machine (JVM)

The client application or operating system must have a java byte-code interpreter to execute

byte-code instructions. The interpreter is a part of a larger program called the JVM. The JVM interprets

the byte code into native code and is available on platforms that support Java.

When the user runs a Java program, it is up to the JVM to load, possibly verify, and then execute it. The

JVM can perform this function from within a browser or any other container program or directly on top

of the operating system.

8

When a browser invokes the JVM to run a Java program, the JVM does a number of things:

It validates the requested byte-code, verifying that they pass various formatting and

security checks.

It allocates memory for the incoming java class files and guarantees that the security of

JVM is not violated. This is known as the class loader module.

It interprets the byte code instructions found in the class files to execute the program.

Interaction of JSP Page with JDBC

Application Server Machine

Client Machine

Browser

with

HTML

DB Server Machine

Here the browser using the web application is not required to support java at all. The JSP has

full control over how many JDBC connections are made to the server. The client never makes direct

JDBC connection to the server. This solution can work readily through a firewall, only standard HTTP

is used between the web server and the client.

As a bonus this solution sends itself to easily secured information simply by adding secured

socket layer support to the web server. Because of this separation of the presentation from the business

logic, which is separated from the database logic, this sort of system is often called three tiers of the

system. Although the application server and database server can also running on the same server

machine.

Web server

JSP Engine JDBC Driver

RDBMS Server

9

There is still one minor problem with this scenario. Project personal accessing the JSP page

containing the embedded JDBC code can easily and inadvertently modify the database access code and

this may result in an erroneous application or even corrupted database. There are solution for this:

Create java beans or java classes that encapsulate all the JDBC operations. This is significantly better

solution. But instantiation, initialization and parameterization of the java class or the beans can still

represent a significant amount of embedded java code within the JSP.

10

BACK-END

ORACLE 10g

Why we are using Oracle (RDBMS)?

Some of the merits of using Oracle (RDBMS) are as under:

Centralization of database.

Client Server Technology.

Security.

Normalization of Data Base.

Relationship.

Transaction Processor.

It gives some internet related features.

Hence because of these features we are using Oracle as a back-end technology.

Weather you are working on LAN projects or Distributed projects, there are two sides of it:-

Front End

Back End

Front End remains on client side. Front end is made for end user who uses our application.

Basically in front end, our input-output forms reside which takes the input from the client and gives

output back to client.

Backend remains on server side and has two components viz.

Server side programs

Data Base

Database is the most important thing in this universe as database gives identity to a thing. It

provides us with a repository where we can store ample amount of data, at one place. Without a

database, existence of a thing is impossible.

While working on a project first step is to design a database.

What is a database?

Data Base is a collection of tables and table is a collection of records in a tabular form i.e. in

row and columns format.

Data Base can be divided into two parts:-

RDBMS

DBMS

We will be using RDBMS (Relational Database Management System) in our project i.e. oracle 10g.

Feasibility Study

A feasibility study is conducted to select the best system that meets performance requirement.

This entails an identification description, an evaluation of candidate system and the selection of best

system for he job. The system required performance is defined by a statement of constraints, the

identification of specific system objective and a description of outputs.

The key consideration in feasibility analysis are :

1. Economic Feasibility :

2. Technical Feasibility :

3. Operational Feasibility:

Economical feasibility

It looks at the financial aspects of the project. It determines whether the management has

enough resources and budget to invest in the proposed system and the estimated time for the recovery

of cost incurred. It also determines whether it is worth while to invest the money in the proposed

project. Economic feasibility is determines by the means of cost benefit analysis.The proposed system

is economically feasible because the cost involved in purchasing the hardware and the software are

within approachable. The personal cost like salaries of employees hired are also nominal, because

working in this system need not required a highly qualified professional. The operating-environment

costs are marginal. The less time involved also helped in its economical feasibility. It was observed that

the organization has already using computers for other purpose, so that there is no additional cost to be

incurred for adding this system to its computers.

The backend required for storing other details is also the same database that is Sql. The

computers in the organization are highly sophisticated and dont needs extra components to load the

software. Hence the organization can implement the new system without any additional expenditure.

Hence, it is economically feasible.

Software Cost :

Apache Tomcat6.0 : Open Source

MyEclipse : 20000/-

Oracle : 15000/-

J2EE Kit : Free

12

Manpower Cost :

Technical Feasibility

It is a measure of the practically of a specific technical solution and the availability of

technical resources and expertise

The proposed system uses Java as front-end and Oracle 10g as back-end tool.

Oracle is a popular tool used to design and develop database objects such as table

views, indexes.

The above tools are readily available, easy to work with and widely used for

developing commercial application.

Hardware used in this project are- p4 processor 2.4GHz, 512 MB RAM, 40 GB

hard disk. This hardware was already available on the existing computer system. The

software like Oracle 10g, Weblogic Server, JDK, JSDK, J2EE and operating system

WINDOWS-XP SP2 used were already installed On the existing computer system. So no

additional hardware and software were required to purchase and it is technically feasible. The

technical feasibility is in employing computers to the organization. The organization is

Team cost : 25000/-

System Cost : 40,000/-

Total Cost : 100000/-

13

equipped with enough computers so that it is easier for updating. Hence the organization has

not technical difficulty in adding this system.

Tools Used :

1) JDK 1.4

2) J2EE Library

3) MyEclipse 8.0

4) Apache-Tomcat 6.0

5) Oracle 10g.

Duration of Project:-

Operational Feasibility

The system will be used if it is developed well then be resistance for users that

undetermined

No major training and new skills are required as it is based on DBMS model.

It will help in the time saving and fast processing and dispersal of user request and applications.

Time Duration

For study 15 days

Designing 20 days

For development 90 days

Testing 15 days

Total time 140 days

14

New product will provide all the benefits of present system with better performance.

Improved information, better management and collection of the reports.

User support.

User involvement in the building of present system is sought to keep in mind the user specific requirement and needs.

User will have control over there own information. Important information such as pay-slip can be generated at the click of a button.

Faster and systematic processing of user application approval, allocation of IDs, payments, etc. used had greater chances of error due to wrong information entered by

mistake.

Behavioral Feasibility

People are inherent to change. In this type of feasibility check, we come to know if

the newly developed system will be taken and accepted by the working force i.e. the people

who will use it.

2.2- Software Analysis

(A) USECASE DIAGRAMS:

A use case diagram is a diagram that shows a set of use cases and actors and their

relationships. A use case specifies the behavior of a system or a part of a system and is a

description of a set of sequences of actions, including variants that a system performs to yield

an observable result of value to an actor. As mentioned below the use case diagrams are

usually specified along with the

requirements analysis or can be used as an aid in the designing also at ten preliminary levels.

Use Case Diagram (User)

Use Case Diagram (Admin/ Moderator)

17

(B) DATA DICTONARY

This part of the Design consists the overall database schema or we can say that tables which consists

various types of records. Table of a database consists attributes,entities,tupels for storing and

manipulating records

Some of the tables are s follows:

System Testing and Implementation

CHAPTER - 4

4.1 TEST CASE DESIGN

4.1.1 WHITE BOX TESTING

This is a unit testing method, where a unit will be taken at a time and tested thoroughly at a

statement level to find the maximum possible errors.

I tested step wise every piece of code, taking care that every statement in the code is executed

at least once. The white box testing is also called Glass Box Testing.

I have generated a list of test cases, sample data, which is used to check all possible

combinations of execution paths through the code at every module level.

White-box test focuses on the program control structure. Test cases are derived to ensure that all

statement in the program control structure. Test cases are derived to ensure that all statement in the

program control structure. Test cases are derived to ensure that all statement in the program has been

executed at least once during testing and that all logical conditions have been exercised. Basis path

testing, a white box technique, makes use of program graphs (or graph matrices) to derive the set of

linearly independent test that will ensure coverage. Condition and data flow testing further exercising

degrees of complexity.

4.1.2 BLACK BOX TESTING

This testing method considers a module as a single unit and checks the unit at interface and

communication with other modules rather getting into details at statement level. Here the module will

be treated as a block that will take some input and generate output. Output for a given set of input

combinations are forwarded to other modules.

Black-box test are designed to uncover errors functional requirement without regard to the

internal workings of a program. Black-box testing techniques focus on the information domain of the

software, deriving test cases by partitioning the input and output domain of a program in manner that

provides through test coverage. The black-box test is used to demonstrate that software functions are

operational, that input is properly produced, and that the integrity of external information are

maintained. A black-box test examines some fundamental aspect of a system with little or no regard for

the integral logical structure of the software.

Graph based testing methods explore the relationship between and behavior of program objects.

Equivalence partitioning divides the input classes of data are likely to exercise specific software

function. Boundary values analysis probes the programs ability to handle data at the limits of

acceptability.

50

4.2 TEST EXECUTION

4.2.1 UNIT TESTING

Unit testing focuses verification effort on the smallest unit of software i.e. the module. Using

the detailed design and the process specifications, testing is done to uncover errors within the boundary

of the module. All modules must be successful in the unit test before the start of the integration testing

begins.

In this project each service can be thought of a module. There are so many modules like Login,

HR Department, Interviewer Section, etc. Each module has been tested by giving different sets of

inputs. When developing the module as well as finishing the development, the module works without

any error. The inputs are validated when accepting them from the user.

4.2.2 INTEGRATION TESTING

After unit testing, we have to perform integration testing. The goal here is to see if modules can

be integrated properly, the emphasis being on testing interfaces between modules. This testing activity

can be considered as testing the design and hence the emphasis on testing module interactions.

In this project the main system is formed by integrating all the modules. When integrating all

the modules I have checked whether the integration effects working of any of the services by giving

different combinations of inputs with which the two services run perfectly before Integration.

4.3 VALIDATION TESTING

User name Validation- Must Be Alphabets [a-z][A-Z], Must Not Be Empty.

Mail Id- Email Id Must is in the form of [email protected], Must Not Be Empty.

Mobile No- Must Be Numeric, Must Not Be Empty.

Address- Must Not Be Empty.

State- Must Not Be Empty.

These above are the Validation Testing We Performed in the Application.

Validation is Quality assurance process of establishing evidence that provides a high degree of

assurance that a product, service, or system accomplishes its intended requirements. This often involves

acceptance of fitness for purpose with end users and other product stakeholders.

It is sometimes said that validation can be expressed by the query "Are you building the right

thing?" and verification by "Are you building it right?" "Building the right thing" refers back to the

user's needs, while "building it right" checks that the specifications be correctly implemented by the

system. In some contexts, it is required to have written requirements for both as well as formal

procedures or protocols for determining compliance.

51

4.4 SYSTEM TESTING

Here the System testing involved is the most widely used testing process consisting of five

stages as shown in the figure. In general, the sequence of testing activities is component testing,

integration testing, and then user testing. However, as defects are discovered at any one stage, they

require program modifications to correct them and this may require other stages in the testing process to

be repeated.

(Component testing) (Integration testing) (User testing)

Testing is the process of detecting errors. Testing performs a very critical role for quality

assurance and for ensuring the reliability of the software. The results of testing are used later on during

maintenance also.

Testing is vital to the success of the system. System testing makes a logical assumption that if the parts

of the system are correct, the goal will be successfully achieved. In adequate testing or non-testing leads

to errors that may not appear until months or even years later (Remember the New York three day

power failure due to a misplaced Break statement).

This creates two problems:

1. The time lag between the cause and the appearance of the problem.

2. The time interval effect of the system errors on files and the records on the system.

A small error can conceivably explode into a much larger problem. Effective testing early in the process

translates directly into long term cost savings from a reduced number of errors.

Another reason for system testing is its utility as a user oriented vehicle before implementation. The

best program is worthless if it does not meet the user requirements.Thus in this phase we went to test

the code we wrote. We needed to know if the code compiled with the design or not? Whether the code

gave the desired outputs on given inputs? Whether it was ready to be installed on the users computer or

some more modifications were needed?

Through the web applications are characteristically different from there software counterparts but the

basic approach for testing these web applications is quite similar. These basic steps of testing have been

picked from software engineering practices.

FUTURE SCOPE AND FURTHER ENHANCEMENT:

Any product despite of its meticulous design and features needs enhancement with time. etutes.in being

no exception needs active enhancement of features and functionality. Following features are proposed

to be implemented in future to make the product more feature rich.

Support of video streaming of classes.

Mechanism of receiving user feedback of provided information.

Facility of providing customized online courses.

CONCLUSION

Etutes.in is a fundamental part of the Software Engineering lifecycle process. Effective use of a

Etutes.in will lead to a more structured approach, resulting in a higher quality product while also

reducing development and support costs. Etutes.in most commonly used in the coding and testing

phases of the software development process. However, Etutes.in can in fact be used for many other

purposes such as general chatting with tutor of the company to sovle our problem where the focus is

given on the online aspect rather than to go and study. Even in software development, Etutes.in are

quite often not limited to simply join forum,create group but it is helpful to enlarge our skills

PREFACE

Education and Training sector in India has witnessed a paradigm shift in recent past. Cities like

Noida, Pune, Banglore, Hyderabad, Chennai etc have emerged as the hub of high end

Education and Training. In these cities, apart from the big I.T. Companies such as HCL,

Wipro, IBM; a lot of smaller and medium training companies have mushroomed and are

providing training services in various domains. Tech Mentro is one of such training company

that provides training services in Noida. Currently, Tech Mentro uses conventional methods of

imparting training in classroom sessions and wants to use internet as a medium for providing

training.

Tech Mentro has two goals in mind:

To provide round the clock educational support to its existing students.

To use Internet as a medium for imparting training.
