1.1 Problem Statement

The ONLINE QUIZ is a web application for to take online test in an efficient manner

and no time wasting for checking the paper. The main objective of ONLINE QUIZ is

to efficiently evaluate the candidate thoroughly through a fully automated system

that not only saves lot of time but also gives fast results. For students they give

papers according to their convenience and time and there is no need of using extra

thing like paper, pen etc.

This project is basically built for students of the engineering collage. It is built on

PHP which is very helpful and doesn’t need much Complexity. So it makes the

project efficient and time saving. This website helps all the students who are the

member of any college. They can check their Domain Knowledge. The System

purpose is to completely automate the old manual procedure of conducting exam to

Online Web Based Examination System.

1.2 Scenario

Location doesn’t matter).

No restriction that examiner has to be present when the candidate

takes the test.

1.3 Available Solution

Solution based on expert system is suggested.

Authentication: every user (faculty, administrator etc.) is authenticated before

allowing to login.

Automation: Examination is automated completely. The faculty can add/delete

the questions according to their subjects. The checking of questions is done by the

system using predefined answers fed to system. Hence results are available

immediately after exam. All exam is available on intranet/internet depending

upon access rights. Modules need to be cleared sequentially hence flags are set.

Passing criteria can be easily set or modified through rules. Time-line can be set

clearing exam and modules.

Study material: Study material is available online and is accessible depending on

modules cleared.

Result Analysis: Various results are prepared and also in-built functionality is

available for analysis of results.

Monitoring of candidate: Expert system can monitor candidates performance .

The rules are added/modified by experts when and as required.

viewed best using 1024 x 768 and 800 x 600 pixels resolution setting. The software

would be fully compatible with Microsoft Internet Explorer for version 6 and above.

No user would be able to access any part of the application without logging on to the

system.

2.3.2 Feasibility study

Feasibility study is the process of determination of whether or not a project is worth doing.

Feasibility studies are undertaken within tight time constraints and normally culminate in a

written and oral feasibility report. I have taken two weeks in feasibility study with my co-

developer. The contents and recommendations of this feasibility study helped us as a sound

basis for deciding how to proceed the project. It helped in taking decisions such as which

software to use, hardware combinations.

The following is the process diagram for feasibility analysis. In the diagram, the feasibility

analysis starts with the user set of requirements. With this, the existing system is also

observed. The next step is to check for the deficiencies in the existing system. By

evaluating the above points a fresh idea is conceived to define and quantify the required

goals. The user consent is very important for the new plan. Along with, for implementing

the new system, the ability of the organization is also checked. Besides that, a set of

alternatives and their feasibility is also considered in case of any failure in the proposed

system. Thus, feasibility study is an important part in software development.

(Figure – 1. PROCESS DIAGRAM FOR FEASIBILITY ANALYSIS)

a) Economic Feasibility

Economical feasibility determines whether there are sufficient benefits in creating to make

the cost acceptable, or is the cost of the system too high. As this signifies cost-benefit

analysis and savings. On the behalf of the cost-benefit analysis, the proposed system is

feasible and is economical regarding its pre-assumed cost for making a system.

During the economical feasibility test we maintained the balance between the Operational

and Economical feasibilities, as the two were the conflicting. For example the solution that

provides the best operational impact for the end-users may also be the most expensive and,

therefore, the least economically feasible.

Economic analysis is most frequently used for evaluation of the effectiveness of the

system. More commonly known as cost/benefit analysis the procedure is to determine

the benefit and saving that are expected from a system and compare them with costs,

decisions is made to design and implement the system.

This part of feasibility study gives the top management the economic justification for the

new system. This is an important input to the management , because very often the top

management does not like to get confounded by the various technicalities that bound to

be associated with a project of this kind.

A simple economic analysis that gives the actual comparison of costs and benefits is

much more meaningful in such cases.

In the system, the organization is most satisfied by economic feasibility.

Because, if the organization implements this system, it need not require any additional

hardware resources as well as it will be saving lot of time.

As we know that the system development costs are usually one-time costs that will not

recur after the project has been completed. For calculating the Development costs we

evaluated certain cost categories viz.

(i) Personnel costs

(ii) Computer usage

(iii) Training

(iv) Supply and equipments costs

(v) Cost of any new computer equipments and software.

In order to test whether the Proposed System is cost-effective or not we evaluated it

through three techniques viz.

Payback analysis

Return on Investment:

Net Present value

b) Technical Feasibility

Technical feasibility centers on the existing manual system of the test management

process and to what extent it can support the system.

Technical feasibility determines whether the work for the project can be done with the

existing equipment, software technology and available personnel. Technical feasibility is

concerned with specifying equipment and software that will satisfy the user requirement.

According to feasibility analysis procedure the technical feasibility of the system is

analyzed and the technical requirements such as software facilities,procedure, inputs are

identified. It is also one of the important phases of the system development activities.

The system offers greater levels of user friendliness combined with greater processing

speed. Therefore, the cost of maintenance can be reduced. Since processing speed is very

high and the work is reduced in the maintenance point of view management convince that

the project is operationally feasible.

c) Behavioral Feasibility

People are inherently resistant to change and computer has been known to facilitate

changes.

An estimate should be made of how strong the user is likely to move towards the

development of computerized system.

These are various levels of users in order to ensure proper authentication and

authorization and security of sensitive data of the organization.

d) Operational feasibility

Operational feasibility criteria measure the urgency of the problem (survey and study

phases) or the acceptability of a solution (selection, acquisition and design phases). How do

you measure operational feasibility? There are two aspects of operational feasibility to be

considered:

Is the problem worth solving or will the solution to the problem work?

There are certain measures, which decide, the effectiveness of the system. These

measures can be collectively called as PIECES.

P (Performance):

The Online Quiz system provides adequate throughput and response time.

I (Information):

The Online Quiz system provide end-users and managers with tamely, pertinent,

accurate, and usefully formatted information.

E (Economy):

The Online Quiz system offers adequate service level and capacity to reduce the costs of

the business or increase the profits of the business.

C (Control):

The Online Quiz system offers adequate controls to protect against fraud and

embezzlement and to guarantee the accuracy and security of the data and information via

authentication checks.

E (Efficiency):

The CCTS make maximum use of available resources including people, time, flow of

forms, minimum processing delays and the like.

S (Services):

The Online Quiz system provide desirable and reliable service to those who need it. The

Online Quiz system is flexible and expandable.

4.1 Database Design

a) ER Diagram :

b) Data Dictionary:

A data dictionary is a catalog-a-repository of the elements in a system. As the name

suggests, their elements center on data and the way they are structured to meet user

requirements and organization needs. In a data dictionary you will find a list of all the

elements composing the data flowing through a system. The major elements are data

flows, data stores and processes. The data Dictionary stores details and descriptions of

these elements.

If analysis want to know characters are in a data item by what other names it is

referenced in the system, or where it is referenced in the system, or where it is issued in

the system, they should be able to find the answers in issued in the system, they should be

able to find the answer in properly developed data dictionary.

The Dictionary contains two types of description for the data following through the

system.

1. Data Elements:

The most fundamental data is the elements. They are building blocks for all other

data in the system. Data elements are also alternatively known as fields, data item

or elementary item.

2. Data Structure:

A data structure is a set if items that are related to one another and described a

components in the system.

5 Project Planning

5.1 Software model used

To solve actual problems in industry software developer or a team of developers must

incorporate strategy that encompass the process methods and two layers and generic phases.

This strategy is often referred to as process model or a software developing paradigm. A

process model for software development is chosen based on the nature of project and

application. The methods and tools to be used, and the controls and deliverables those are

required. All software developments can be categorised as problem solving loop in which

four distinct stages are encountered: Status quo, problem definition, technical development

and solution integration.

Regardless purpose of the process model that is chosen for a software project of all the stages

co exist simultaneously at some level of detail.

Our project follows the waterfall model

The stages of "The Waterfall Model" are:

Requirement Analysis & Definition: All possible requirements of the system to be

developed are captured in this phase. Requirements are set of functionalities and

constraints that the end-user (who will be using the system) expects from the system. The

requirements are gathered from the end-user by consultation, these requirements are

analyzed for their validity and the possibility of incorporating the requirements in the

system to be development is also studied. Finally, a Requirement Specification document

is created which serves the purpose of guideline for the next phase of the model.

System & Software Design: Before a starting for actual coding, it is highly important to

understand what we are going to create and what it should look like? The requirement

specifications from first phase are studied in this phase and system design is prepared.

System Design helps in specifying hardware and system requirements and also helps in

defining overall system architecture. The system design specifications serve as input for

the next phase of the model.

Implementation & Unit Testing: On receiving system design documents, the work is

divided in modules/units and actual coding is started. The system is first developed in

small programs called units, which are integrated in the next phase. Each unit is

developed and tested for its functionality; this is referred to as Unit Testing. Unit testing

mainly verifies if the modules/units meet their specifications.

Integration & System Testing: As specified above, the system is first divided in units

which are developed and tested for their functionalities. These units are integrated into a

complete system during Integration phase and tested to check if all modules/units

coordinate between each other and the system as a whole behaves as per the

specifications. After successfully testing the software, it is delivered to the customer.

Operations & Maintenance: This phase of "The Waterfall Model" is virtually never

ending phase (Very long). Generally, problems with the system developed (which are not

found during the development life cycle) come up after its practical use starts, so the

issues related to the system are solved after deployment of the system. Not all the

problems come in picture directly but they arise time to time and needs to be solved;

hence this process is referred as Maintenance.

5.2 Gantt Chart

Gantt chart is a graphical representation of the duration of time against the progression

time. A Gantt chart is a useful tool for planning and scheduling projects. A Gantt

chart is useful when monitoring a projects progress. A gantt chart is a type of bar

chart that illustrates a project schedule. It illustrates the start and finish dates of the

terminal elements and summary elements of a project.Terminal elements and

summary elements comprise the work breakdown structure of the project.

Each member of our group has been allotted a set of tasks to be completed for the project

implementation. The work load Distribution and the role of each member is defined hereby:

5.3 Responsibility Distribution

5.3.1 Site layout and Database Management:

This involves designing of web pages to be displayed and storing the information related

to student records of personal information and their performance in the tests attempted.

The task involves maintaining sessions as long as the user logs in to take the test and php

coding.

The Database Management includes managing account information of students and

administrator. All queries like Insertion of new student records, updating any changes in

student and administrator profiles, maintaining records of scores in the tests taken ,

deletion of accounts etc

5.3.2. Preparation of Tests (Framing of Questions)

The basic requirement of online examination includes registration, user management,

report generation, question paper matrix entry ,question pool management, data entry,

conduction etc.

I would basically be dealing with question paper generation, question paper matrix and so

on i.e the framing of questions

PROCESS FLOW DIAGRAM

Questions are framed on the basis of difficulty levels (easy, medium and hard). The

Questions are framed according to the requirements of the students like the specific

topics they required to be covered in any subject pertaining to the feedback provided.

There are three sets of questions , one for each stream (PCM,PCB,PCMB).

Creating data banks and tests with the Online Examination System

* Online examination questions can be categorized according to topic, types, etc.

(libraries)

Navigation tools/buttons can be selected for a test, and these buttons can be switched.

* on/off per question/test, e.g. backward/forward buttons.

* Students can be forced to go through all the questions at least once, before exiting the

test.

* Students can be allowed to exit the test before completing all the questions.

* After exiting a test, students can continue the test from the last question they

answered.

* A specific date for a test to be active can be set.

Online Examination System Feedback

* Feedback on test results can be set on/off.

* Feedback per question can be set on/off.

* Customized feedback per question/test.

* The event of feedback can be set, e.g. after all the questions/after each question/ after

a section or library/not at all.

* The examination system indicates what the student answered as well as the correct

answer.

* Extra time can be set for students to work through the feedback after test completion.

* Score per question can be displayed in the feedback.

unanswered. The students scoring low marks are also indicated for improvement in their

performance.

6 Salient Coding Features Used

Salient feature means "characteristic". Or you may interpret it as "notable feature‖.

Seeing to the step rise in the demand of website design many software companies are

now offering website design and development services. Nowadays the services of an

expert professional website designer have become inevitable just because every business

is flocking to get a successful web design.

Salient Feature consist a term i.e Unique Selling Proposition (also Unique Selling

Point or USP) is a marketing concept that was first proposed as a theory to explain a

pattern among successful advertising campaigns of the early 1940s.

Some of the features are:

Unlimited verisimilar test paper.

Real time self assessment with score cord and answer rkey.

Daily updating of question bank by the faculty.

Design and developed by B-tech student.

Focus on fundamental and conceptual learning.

Fully customizable unlimited.

Subject based test paper

U.S.P. is widely misunderstood and gives a precise definition in three parts:

Each advertisement must make a proposition to the consumer. Not just words, not

just product puffery, not just show-window advertising. Each advertisement must

say to each reader: "Buy this product, and you will get this specific benefit."

The proposition must be one that the competition either cannot, or does not, offer.

It must be unique—either a uniqueness of the brand or a claim not otherwise made

in that particular field of advertising.

The proposition must be so strong that it can move the mass millions, i.e., pull

over new customers to your product.

9. Testing

9.1 Testing Objectives:

To find Uncovered Errors based on Requirement.

Ensure the Product is Bug Free before shipment/release.

Quality is ensured.

9.2 Testing Strategy:

9.2.1 Static tests:

The software is not executed but analyzed offline. In this category would be

code inspections (e.g. Fagan inspections), Lint checks, cross reference checks,

etc.

9.2.2 Dynamic tests:

This requires the execution of the software or parts of the software (using stubs).

It can be executed in the target system, an emulator or simulator. Within the

dynamic tests the state of the art distinguishes between structural and functional

tests.

9.2.3 Structural tests:

These are so called "white-box tests" because they are performed with the

knowledge of the source code details. Input interfaces are stimulated with the aim

to run through certain predefined branches or paths in the software. The software

is stressed with critical values at the boundaries of the input values or even with

illegal input values. The behavior of the output interface is recorded and

compared with the expected (predefined) values.

9.2.4 Functional tests:

These are the so called "black-box" tests. The software is regarded as a unit with

unknown content. Inputs are stimulated and the values at the output results are

recorded and compared to the expected and specified values

9.2.5 Load testing:

The application is tested against heavy loads or inputs such as testing of web sites

in order to find out at what point the web-site/application fails or at what point its

performance degrades. Load testing operates at a predefined load level, usually

the highest load that the system can accept while still functioning properly. Note

that load testing does not aim to break the system by overwhelming it, but instead

tries to keep the system constantly humming like a well-oiled machine .In the

context of load testing, extreme importance should be given of having large

datasets available for testing. Bugs simply do not surface unless you deal with

very large entities such thousands of users in repositories such as

LDAP/NIS/Active Directory; thousands of mail server mailboxes, multi-gigabyte

tables in databases, deep file/directory hierarchies on file systems, etc. Testers

obviously need automated tools to generate these large data sets, but fortunately

any good scripting language worth its salt will do the job.

9.2.6 Domain testing:

Domain testing is the most frequently described test technique. Some authors

write only about domain testing when they write about test design. The basic

notion is that you take the huge space of possible tests of an individual variable

and subdivide it into subsets that are (in some way) equivalent. Then you test a

representative from each subset.

9.2.7 Regression testing:

Regression testing is a style of testing that focuses on retesting after changes are

made. In traditional regression testing, we reuse the same tests (the regression tests).

In risk-oriented regression testing, we test the same areas as before, but we use

different (increasingly complex) tests. Traditional regression tests are often partially

automated. These note focus on traditional regression. Regression testing attempts

to mitigate two risks:

A change that was intended to fix a bug failed.

Some change had a side effect, unfixing an old bug or introducing a new bug.

9.2.8 Users testing:

In this type of testing, the software is handed over to the user in order to find out if

the software meets the user expectations and works as it is expected to. In software

development, user acceptance testing (UAT) - also called beta testing, application

testing, and end user testing - is a phase of software development in which the

software is tested in the "real world" by the intended audience. UAT can be done by

in-house testing in which volunteers or paid test subjects use the software or, more

typically for widely-distributed software, by making the test version available for

downloading and free trial over the Web. The experiences of the early users are

http://whatis.techtarget.com/definition/0,,sid9_gci212063,00.html

forwarded back to the developers who make final changes before releasing the

software commercially.

9.2.9 Alpha testing:

In this type of testing, the users are invited at the development centre where they use

the application and the developers note every particular input or action carried out by

the user.

Any type of abnormal behaviour of the system is noted and rectified by the

developers.

9.2.10 Beta testing:

In this type of testing, the software is distributed as a beta version to the users and

users test the application at their sites. As the users explore the software, in case if

any exception / defect occurs that is reported to the developers. Beta testing comes

after alpha testing. Versions of the software, known as beta versions , are released to a

limited audience outside of the company. The software is released to groups of people

so that further testing can ensure the product has few faults or bugs. Sometimes, beta

versions are made available to the open public to increase the feedback field to a

maximal number of future users.

9.2.11 Test Case Specification:

Text boxes cannot be left blank. Account number field has to be given in numbers.

One cannot buy an item without registering first.

9.2.12 Testing Result:

Testing is successfully completed on all test cases provided above.

10. Cost of the project

It is the responsibility of the project manager to make accurate estimations of effort and

cost. This is particularly true for projects subject to competitive bidding where a bid too

high compared with competitors would result in losing the contract or a bid too low could

result in a loss to the organisation . This does not mean that internal projects are

unimportant. From a project leaders estimate the management often decide whether to

proceed with the project. Industry has a need for accurate estimates of effort and size at a

very early stage in a project. However, when software cost estimates are done early in the

software development process the estimate can be based on wrong or incomplete

requirements. A software cost estimate process is the set of techniques and procedures

that an organisation use to arrive at an estimate. An important aspect of software projects

is to know the cost are-

10.1 Planning: Our web site is a package to assist students preparing for placements

.Some students lack guidance in the course of their preparation for job. So this site is

developed taking in consideration their problems and hence , includes all necessary

details regarding how to prepare and what to prepare .So it provides the proper guidance

and also keeps the information up-to-date.

10.2 Technical Specifications: The purpose of a technical specification in a software

development project is to define the customer's technical requirements that will be

addressed by the project.Our website is easy to operate by any user which are going to

preparation for job. User can post their queries on the site and discuss the solution for

their queries. All the comment are save in our database and administrator have a power

to delete comment or modify comment if it is not proper.

10.3 Design Specifications: The purpose of a Software Design Specification (SDS) is to

define the software that is to meet the functional requirements for the project. It is the

stage at which the developer specifies the detailed design of the software system,

produces the program code to realise that design, tests the individual programs and

integrates them into the complete software system.

10.4 Maintenance: Once site is online, it will inevitably need to be updated to keep

your content fresh. Sometimes it's a simple change, like changing a date, or adding an

event or you may want to add a new post or functionality to your site involving site-

wide modification.

Our professional Website Maintenance service delivers
