Chapter 2 –  Introduction  Introduction

Background:-

As the name of the project “on line Examination” suggests, the system/application has to manage the examination for various department of an academy. So to keep the information correct and fast, it will manage the status/information of that examination of that examination so one can get the details of exam as per their program.

Earlier it was a very time consuming and tedious process where both students as well as university used to perform all tasks manually be it Student Registration, Sqtting Question Papers, Setting Schedules to finally declaring the result. It was cumbersome since these details were now generated, managed and kept in computers.It was still not that much simpler Later the process  became a lot easier when computer system were introduced and all for students because they were stll expected to come in person to register, appear for exam at exam center and for all those formalities.

 Now we are expected to develop an web application which converts all of these tasks automized as well as web enabled. There are applications already working in this area like MCSE, CCNA which conducts their examination online.

We, as a 4th sem student of MCA are making this project by taking help from theses already working and tested applications as well as making our own set of improvements. i mprovements.

This application is coded in Dot Net. This Software project is very much helpful to students, Examination department and Exam controller. It stores the information about Students, Exams, Report, Results, Student‟s details and and Fee Status etc. As we know that this software  project is coded in Dot Net programming language, it is user friendly. That means this software is easy to operate. Even a person having less knowledge of computer can easily operate is, he

will be guided throughout by the software to operate it. This Software is a best effort of changing in paper work to electronic work. This application is divided into many module, and each module is related to different part of code. This integration makes the project very user friendly. Another advantage of this software is the database that is designed very strongly, the current and  previous information is stored in this database and maintain the database very easily.

university used to keep all the details in files manually.

Chapter 3  – Objective

Chapter 3 - Objective The objective of the project “On Line Examination” is to make evaluation and conduction of examination massive but simple, cost effective and faster. They are as follows : 

To provide an interface through which student can appear for examination online for objective as well as subjective type questions.



To provide registration for students done by themselves.



To not provide facility of copy and paste while attempting the Subjective questions on the web page.



When the student starts the exam the timer will start automatically and show the student how much time is left.



The questions will be display randomly from question bank.



Objective answers will be checked automatically by the system from the database



For subjective answer manually checking by exam department will take place.



To provided user name and password facilty and credentials should be checked properly at the time of login for student,expert, controller and Exam Dept Admin.



To provide an interface from where controller will create new Expert and Admin for Exam Dept.



The authority to modify the criteria is provided to the controller of examination.



To facilitate Experts to send a collection of questions in Question Bank.



The Exam Dept will manage the question bank sent by experts.



To facilitate Exam Dept Admin to make schedule and declare Result.

Chapter 4 - Purpose, Scope and Applicability

Purpose:-

Through this package we provide a fully customized web application. This system is an automated system so that the functional working of it is effective and time saving. In this modern era time is the most precious thing, so in context of time the new system will be effective to do a group of task in easy and secure manner.

To appear for an exam in manual system in an university is very time consuming process. Now the purpose of this system is to overcome the shortfall faced in the previous systems already working in the area.

The website will have to be secure, and properly working on WAN. It should be speedy with good interface. The university may conduct examination in various countries and in different languages. It should support multiple platforms at least those used by people commonly.

Scope:-

Methodology of the system is clear that result in the complete and proper working of the system from the requirements achieved. it contains the working model for the development of system. A sequential step of model is follwed to develop the system so that it will maintain various software engineering fetures/parameters.

 No need to take leave, visit a different town, city or even states in some cases. People can appear right from their laptop or home desktop.

Assumptions:

To develop this application, we‟ve taken into account some assumptions. They are:

1. University will provide each student a unique student Id during enrollment time. The  purpose of this is so that no one can register on behalf of any other student. and only the student himself/herself can register for the examination using this id. 2. Student login name will be generated automatically by concatanating student first Name and Enrollment No.

Like : Pradeep Singh has student id

  13P



So, Pradeep‟s student login here will be   Pradeep_P13

3. Expert login name will be generate same as student login name but with small change.

like : Expert Login = (Expert First name +Course Name)

The courses will be fed by hard-coding.

Chapter 5 - SURVEY OF TECHNOLOGIES

To develop this package different types of tools and database are used which are as follows:

1.ASP.NET 2005

2.Framwork 2.0

3.Microsoft-sql server 2000

4. Microsoft word processor

ASP.NET 2005:

ASP.NET 2005 is a Microsoft technology for building the web based application and services.A ASP.NET application consists of forms ,controls,classes and procedures.

Forms are windows upon which you build your user interface are the building blocks of the user interface. Controls also called activeX conrols, are interface tools , such as labels ,textbox and command buttons, that you use to display information to the user, gather information from the user, and respond to user actions. Classes are templates from which you can create your own objects at run time.

Procedures are small routines you write that are callable from anywhere in your application. These routines will perform a function for you that you write once but can call many times.

An application is made up of forms, modules and classes. A form is made up of properties, events and controls. Controls are also made up of properties and events

Some Features Of ASP.NET



Language interoperability : a one language code is to interact with other language.



EDP(Event driven programming language): it is a Event Driven Programing language(i.e. we write code on its event and drive the program).



Rapid Application Development(RAID).



Allows the creation of COM components such as activeX controls.



Includes good debugging facilities.

Framwork 2.0

Dot net framework is a platform that is provided by Microsoft technology in which we can develop web based application,window based application and console base application with C#(c sharp),VB and J#(J sharp) and other 22 Language.

Microsoft-sql server 2000

Microsoft SQL Server fulfills these responsibilities :



Reduction and redundancy :

Centralized control of the dba avoids the unnecessary duplication of data and effectively Reduces the total amount of data storage required. It also eliminates the extra processing and of the inconsistencies eg. Same format of grade card for all student.



Sharing data :

Any number of application program of user‟s can share the same database .

For example we can access the list of study centers.



Data integrity :

Data integrity means that the data contains in the database both accurate and consistent.



Data security :

In this facility the confidential data must not be accessed by unauthorized person.



Rapidly Accessing Data :

SQL Server provides rapid access to data by utilizing indexes and storing frequently accessed data in memory.



SQL Server Enterprise Manager :

The Enterprise Manager is the central console from which most SQL Server databasemanagement tasks can be coordinated. SQL Enterprise Manager provides a single interface from which all servers in a company can be managed.

Chapter 6 - Front End User The .Net Initiative

Microsoft has introduced the .NET initiative with the intension of bridging the gap in interoperability between application. It aims at integrating various programming

.

The .NET initiative offers a complete suite for developing and deploying applications. This suits consists of .NET services, and the .NET framework.



.Net Products :-  Microsoft has already introduced Visual Studio .Net, which



Is tool for developing .Net applications by using programming languages such as Visual Basic, C# and Visual C++. To ensure interaction between different applications, all .Net  products use Extensible Markup Language (XML) for describing and exchanging data  between application.



.Net Services :-  .Net delivers software as web services. Therefore, User can subscribe to

a web service and use it as long as they need it, regardless of the hardware and software  platform. Microsoft is coming up with its own set of web services, known as my services. These services are based on the Microsoft Passport Authentication service, in addition to the web services provided easily with the .Net env ironment.

The .Net Framework :-  it is the foundation on which us design, develop and deploy application. Its consistent and simplified programming model makes easier to built ap plications.

Chapter 7 - Back End User

This is the part of well known software package called as the Microsoft Office. It is designed to built the various database, and to perform other data work. SQL provides an extremely powerful, easy to use database that will serve our needs when you required the power of fully relational database. SQL is also helpful create a variety of database as well as how to enter, edit and final data in existing database.

SQL :

SQL server 2007 utilities, such as backup and restore, run much faster and have less effect on server operations. SQL Server 7.0 also includes a variety of new features designed to support the underlying database architecture and to provide more flexible system management. SQL Server also include a number of new features designed to reduce database backup and recovery times. A different backup captures only those data pages that have changed after the last database backup. Many times differential backup can eliminates much of the time the server spends rolling transaction forward. With SQL Server 7.0 a portion of the database can  be restored or rolled forward to minimize recovery time in the event of media failure. Restoring a backup is easy because the restore process automatically creates the database and all the necessary files. SQL server 7.0 supports backup to same tape media with other  backup, such as those written by the Microsoft Windows NT backup program.

Chapter 9 Feasibility Study

Introduction: The feasibility study of any system is mainly intended to study and analyze the proposed system and to decide whether the system under consideration will be viable or not after implementation. That is it determines the usability of the project after deplo yment. To come to result a set of query is answered keeping the efficiency of the software and its impact on the domain for which it was developed. It main emphasis is on the following three questions elucidated below as:

What are the user‟s requirements and how does a candidate system meet them?

What resources are available for the proposed s ystems? Is it worth solving the problem?

What is the likely impact of the proposed system on the organization? I.e. how does the proposed system fit with in the organization?

Thus since the feasibility study may lead to commitment of large resources, it becomes necessary that it should be conducted competently and no fundamental errors of judgment are made. Different types of feasibility study and the way we performed on our project “On Line Examination” .

Subpages (1): NEXT Technical Feasibility:

NEXT Technical Feasibility: In technical feasibility, we study all technical issues regarding the proposed system. It is mainly concerned with the specifications of the equipments and the software, which successfully satisfies the end-user‟s requirement. The technical needs of the system may vary accordingly but include:



The feasibility to produce outputs in a given time.



Response time under certain conditions.



Ability to process a certain volume of the transaction at a particular speed.



Facility to communicate data.

Under this analysis process questions like (i) does the compatible platform exist within our domain or can we procure it? (ii) Does the proposed equipment have the technical capacity to hold the data required using the new system?.

Both at the development site and at server where we will be hiring the space for the website, and also the database would it be possible to upgrade the system after it is developed and implemented, if necessary? And would the recommended technology guarantee the reliability, accuracy and data security? This analysis process requires more emphasis on system configuration given more importance rather than the actual hardware specifications.

. The configuration of the existing systems is:



Processor : Pentium III, 500 MHz (or above)



Memory



Secondary storage : 20 GB (or above)

: 128 MB (or above)

For Software there are following alternatives:

Operating System :Window 98,2000,XP,NT

Development tools :ASP.Net ,C# ,HTML,DHTML

Database

:Microsoft SQL server 7.0

Documentation tool: MS-Word

Subpage(2):Economical Feasibility ====================================

Meaning : re there sufficient benefits in creating the system to make the acceptable? Or are the costs of not creating the system so great that it is advisable to undertaken the project.

This will include three major costs as described below :



Cost of Hardware and Software



Cost of Software to be acquired to build and run the product is a one time cost.



Buying a back and database is the major part of hardware and Software cost. Comparison  between the oracle database high cost and better features with the SQL server low cost and better support for the same vendor operating system make this decision need oriented.

Benefits in reduced cost, error and saving will be made by reduction of present system expenses, time saving and increased accuracy.

Cost Avoidance :

Future cost reduction in form of reduction in the number of administrative staff needed and manual records maintains in organization.

Rise in cost will be avoided.

Operational Feasibility : Meaning : The system will be used if it is developed well then be resistance from users that undermine the possible application benefits.

Clients Supports :

Client and user support for present system is there, as the current procedure used takes more time and effort than proposed system.

 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 application.

 New product will provide all the benefits of present system with better performance such as 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 own information. Important information such as Test result can be generated at the click of a button.

NEXT Chapter 21 User Interface Design NEXT Chapter 22 Security Issues Security is an important issue for modern IT system. S ystem administrator and security administrator are responsible for safeguard‟s organization data and computing infrastructure. Password Encryption: Whatever security measures taken, in any case if anyone with

destructive or malicious mind gets access to the database he can temper the critical data. To restrict it we‟ve used encrypting algorithm facilitated to us by MicroSoft ASP.Net .

Two algorithms are there



SHA1- It takes the password and encrypt it in a string of 40 characters



MD5- It takes the password and encrypt it in a string of 32characters



The beauty of these algos are that whatever be the length of password the length of converted string remains same.



However a question arise here that if this thing is that good then why didn‟t we used it for storing each and every data????



The answer lies in the fact that not all data are needed to be encrypted as long as we keep the critical data(like password encrypted and safe). It will only increase the load on server and network with no additional advantage. So we‟ve not used this encryption algo on all data blindly.



We have implemented different approach related to security issue for our project “Online Examination” :



Authorization:



Super Admin has authorized to give permission to admin for the registration of the students.



Authentication:



Only registered students can appear for the examination. Every registered student has different and unique UserId.



Information Integrity:



Only Super admin has right in the modification of the information. There is no possibility  by the end user or unauthorized user of hacking the information.



Detection:



Super Admin will have a bank up of the project. Also there is a complex and alphanumeric password for admin and student. Super admin itself has a complex and

alphanumeric password. There is a option for changing the password by all the admin and itself after every month.

NEXT Chapter 23 Test Case Design: Student Login: Appearing for examination, Student must have to be begin through student

login form. There are three field in the student login page and Every field has to filled by student. Student can not used character in the login id field. Student registration will be cancelled automatically by the system after appearing in the examination.

Admin Login :- To register the student admin has to login first. The Id field is numeric.

Registration :- Userid and password will be generated by the administrator.

VALIDATION CRITERIA

1. In each form, no field which is not nullable should be left blank. 2.

All numeric fields should be checked for non-numeric values. Similarly,

text fields like names should not contain any numeric characters. 3.

All primary keys should be automatically generated to prevent the user

from entering any existing key. 4.

Use of error handling for each Save, Edit, delete and other important

operations. 5.

Whenever the user Tabs out or Enter from a text box, the data should be

validated and if it is invalid, focus should again be sent to the text box with  proper message.

Next Chapter 24 IMPLEMENTATION AND DESIGN Implementation Approaches-

Implementation is the second-last phase of any SDLC. It takes place after coding is  performed and the system is passed through a strict testing phase and is free against any development-time error. There are many implementation approaches and based on the requirement and constraints, the best suitable tech is used.

For our On-Line Examination System, we have used „Direct Implementation‟ approach. In this approach the old system which is being used is replaced by the new developed system. . The advantage of this technique is it is very cost effective and the new system helps in various ways. As it overcome the all disadvantages of the previous system and maintain reliability. This system is tested first very carefully. Then after it is being used in a ny organization.

NEXT CHAPTER 25 Coding Details and Code Efficiency NEXT CHAPTER 27 Testing Approach Unit Testing

Unit testing focuses verification error on the smallest unit of software design  –  the software component or module. Using the component-level design description as a guide, important control paths are tested to uncover errors within the boundary of the module. The relative complexity of tests and the errors those tests uncover is limited by the constrained scope established for unit testing. The unit test focuses on the internal processing logic can be conducted in parallels for multiple components

Unit Test Considerations:

Unit Testing

Unit testing focuses verification error on the smallest unit of software design  –  the software component or module. Using the component-level design description as a guide, important control paths are tested to uncover errors within the boundary of the module. The relative complexity of tests and the errors those tests uncover is limited by the constrained scope established for unit testing. The unit test focuses on the internal processing logic can be conducted in parallels for multiple components

Unit Test Considerations:

The tests that occur as part of unit tests are illustrated. The module interface is tested to ensure that information properly flows into and out of the program unit under test. Local data structures are examined to ensure that data stored temporarily maintains its integrity during all control structure are exercised to ensure that all statements in a module have been executed at least once. Boundary conditions are tested to ensure that the module operates properly at  boundaries established to limit or restrict processing. And finally all error handling paths are tested.

Test of data flow across a module interface are required before any other test is initiated. If data do not enter and exit properly, all other tests are moot. In addition, local data structures should be exercised and the local impact on global data should be ascertained during unit testing.

Selective testing of execution paths is an essential task during the unit test.

Among the more common errors in Computations are:

1. Blank test box entries.

2. Misunderstood or incorrect Entries i.e. In Name Fields numeric v alues are entered.

3. Incorrect Initialization.

4. Incorrect symbolic representation of an expression.

Subpages (1): NEXT Unit Test Procedures: NEXT Unit Test Procedures: Unit testing is normally considered as an adjunct to the coding step. The design of unit tests can be performed before coding begins or after source code has been generated. Each test case should be coupled with a set of expected results.

Integrated Testing

Integration testing is systematic technique for constructing the software architecture while at the same time conducting tests to uncover errors associated with interfacing. The objective is to take unit tested components and build a program structures that has been dictated  by design.

Modifications and Improvements:

In testing phase, beside some small errors we got to know about as serious error which we didn‟t thought about on.

We didn‟t proper use of “DataSet” . Because of this our site was running slowly. After  proper using of DataSet our site becomes fast, i.e. page loaded very quickly. What we were doing that for each item we have opened the connection. But at page load we brought all the item and then start retrieving one by one. This is the very big improvement in our site.

RESULT AND DISCUSSION

Test Reports

Super Admin Login:

If the id field is filled by character the error generated and shown by “*”. That it should  be numeric.

If the user id or password does exist then error will be generated that “ User Id or  password does not exist.

Registration:

Required field validator means we have fill the text.

Compare to validate mean the field should match from the previous field.

Student Login:

Appearing for examination, Student must have to be begin through student login form. There are three field in the student login page and Every field has to filled by student.

Student can not used character in the login id field.

Student registration will be cancelled automatically by the system after appearing in the examination.

Admin Login :-

To register the student admin has to login first. The Id field is numeric.

NEXT TEST REPORT NEXT Chapter 20 - Future Scope of the Project The development of this project surely prompts many new areas of investigation. This  project has wide scope to implement it in any University/Institution having multiple paper there. This project covers all functionalities related to On-Line Examination Hall Hence it can be implemented any-where else after minute organization level customization

Moreover some parts of the project have remained uncompleted due to some reasons. First of all limitations of our project, which has been discussed in previous topic make place for future enhancements. Though that was not the part of objective of our project but it would have great to implement that provided we‟d enough time.

Some of them are all those which are enumerated in the limitation section l ike: 

Online Payment
