Onine exam 1

ONLINE EXAMINATION
ABSTRACT
Online examination is the process of conducting the exam through online.
The user who has to undergo the exam has to login to the system with proper
authentication from administrator. The administrator has the rights to create
account for the users and can configure the subject and the number of questions for
the exam.
Various reports can be generated to view the results in well organized
manner. This project is designed such a way that it can be used in training centers
to conduct exams.
The project is designed in modular way. The modules of this project are
Master, Exam and Report. Master module is used for adding student names,
subjects, questions and examiners. Exam module is responsible for conducting the
exam. The specified students mark will be displayed at the end.
This project will be developed using ASP .Net as front end with SQL Server
as backend.

INTRODUCTION
PROBLEM DESCRIPTION
The first step in the software development life cycle is the identification of
the problem. As the success of the system depends largely on how accurately a
problem is identified.
The project entitled “ONLINE EXAMINATION SYSTEM” developed for
the computerization of the work done in online examination to the client. The
System is developed using ASP.Net 2005 as front end and Sql Server 2005 back
end, which works in .Net framework version 2.0.
Online Examination System (OES) is a Multiple Choice Questions (MCQ)
based examination system that provides an easy to use environment for both
Administrator and Students appearing for Examination. The main objective of OES
is to provide all the features that an Examination System must have, with the
“interfaces that doesn’t Scare it’s Users!” . The purpose of the system is to test the
Domain knowledge of the students with respect to the particular technology. The
manual procedure used for conducting exam is time consuming process and error
prone due to human limitations. The System purpose is to completely automate the
manual procedure of conducting exam to Web Based Examination System.
 Administrator Module
 Candidate Module
 Staff Module
 Report Generation
Admin has to generate question pattern as per exam categories like C,
DBMS, VB.Net, Java, Computer Networks, Linux and Aptitude. Admin has rights

to view the score of each student. After login, candidates are allowed to take part in
the exam. Questions are multiple choices. They can select the correct choice for
every question and so on. Candidate can get the result from admin. Students from
any location with facility can write exam. No need to wait for result, results will be
displayed as soon as test is completed.

SOFTWARE DESCRIPTION
THE .NET FRAMEWORK
The goal in application development is always the same: create the best
possible software in the least amount of time. Yet the bar is continually raised, as
demands from customers increase. To meet these demands, the platforms
developers build on and the tools they use must get better and better evolvement
needed compulsorily.
The .NET Framework provides a clear example of this. First released in
2002, version 2.0 of the Framework appeared three years later. The .NET
Framework 3.0, released in 2006, was a major update that added a number of new
technologies, while the latest version, the .NET Framework 3.5, includes more
useful additions.
Alongside this evolution, Microsoft’s flagship tool for creating .NET
applications has also moved forward. The latest release, Visual Studio 2008, offers
a range of improvements for creating .NET applications. Every step in this path has
been aimed at providing a better and more productive environment for the people
who create Windows software.

This overview provides a big-picture view of the .NET Framework 3.5.
While a basic knowledge of the .NET Framework is assumed, this description
focuses on the technologies added in the .NET Framework 3.0 and 3.5. The goal is
to make clear what this widely used foundation for Windows applications provides
today.
The Challenges of Building Modern Applications
Creating a modern application is not a simple task—the requirements are
substantial. Traditional concerns such as creating effective business logic and
allowing access via a Web browser are still important, but that concerns no longer
enough. Modern applications present a range of new challenges, including the
following:
Users increasingly expect Web browser interfaces to act like installed
Windows applications. Loading a new page whenever something has changed is no
longer sufficient it’s just too slow. What’s needed is better support for responsive
browser applications.
Data remains central to most applications. How that data can be represented,
however, has expanded considerably. Relational data is still important, as is
mapping between objects and relations. Yet the amount of data represented using
XML continues to increase, a trend that’s not likely to change. And even though
it’s not always viewed in this way, a running program’s objects also contain data.
A technology that allowed consistent access to diverse data would help developers
create applications in less time and with fewer errors.
Applications commonly communicate with other applications, both inside
and outside the organization. Modern applications also must often fit into a

service-oriented architecture (SOA), exposing some of their functionality as
interoperable services accessible by other software. Achieving these goals requires
support for service-oriented applications.
Organizations are increasingly taking a process-oriented view of what need
to do. Since most applications automate some part of a business process, it can be
useful to make the steps in this process explicit in the code. An effective way to do
this is by using workflow technology, an approach that requires support for
workflow-based applications.
The requirements for a modern user interface have grown significantly.
Providing real business value can commonly require working with various kinds of
documents, using two- and three-dimensional graphics, displaying video, and
more. Meeting these needs requires a unified approach to diverse user interfaces.
The people who use an application commonly need a way to convey
information about who they are. Many different technologies for defining and
using a digital identity are in use, and problems such as phishing are common.
Given this, a modern application and the people who use it can benefit from
consistent user control of digital identities.
Given that today’s applications commonly need to tackle some or all of
these challenges, the platform those applications are built on should also address
all of them. The goal of the .NET Framework 3.5 is to do this for Windows
software.
.Net Framework Components
Visual Basic sits at the top of the framework (along with the other
languages in Visual Studio.net). Below that is the Common Language

Specification (CLS). This specification is a set of rules that govern the minimum
language features that must be supported to ensure that a language will interoperate
with other CLS-compliant components and tools. As long as a language conforms
to the CLS, it is guaranteed to work with the CLR. In this way, when third-party
compilers target the .net framework, as long as they conform to the CLS, the code
is guaranteed to work.
User might also notice that VB is now and “equal” or peer of C++, C# and
any other language that is .net compliant. Visual Basic.net shares the same
variable types, arrays, user-defined types, classes, graphical forms, visual controls
and interfaces as these other languages.
Web Services
Web Services provide a Web-enabled user interface with tools that include
various HTML controls and Web controls. Forms creating using Web Services are
the same as forms created for a Windows application. The code behind a Web
form is the same as the code behind a Windows form. The markup language that is
used by Web forms is still there, but the Web form applications generate it for user.
User Interface
At the same level as Web Services is the User Interface. The User Interface
is where Windows forms live. It also provides code for drawing to the screen,
printing, rendering text and displaying images.
Data and XML

Both Web Services and the User Interface sit on top of the Data and XML
block. As user will learn later in this paper, XML (or extensible markup language)
plays just as important of a role as data. XML is used to provide a text view of
data that can be shared between services on the same PC or passed through a
firewall to a web server across the country using SOAP (more on SOAP a little
later).
Base Class Library
The base class library (BCL) is underneath the Data and XML block. This area is
the origin for the base class of all .net programs. Everything in Visual Basic.net is
an object, and all objects originate from a class named System. The BCL also
provides collections, localization, text objects, interoperability with non-.net code
and ActiveX controls and a variety of other services.
The Common Language Runtime
At the base of the .net framework is the common language runtime (CLR).
Much like the Java Virtual Machine, the CLR is needed to make .net code run on
any machine. The CLR is a set of resources that any .net program can take
advantage of, from any .net-supported language. All languages will be more equal
in capability than they ever have before.
The CLR includes support for the BCL, where the architecture for controls
and forms actually live. It is also responsible for managing threads and exceptions
(replacing the Err object in VB 6). Garbage collection is also handled by the CLR.

The CLR takes code generated by VB and converts it to the native language
of the current platform. Through this conversion, the magic of multi-platform
execution is achieved. Now VB programmers can write code in VB syntax and the
CLR is responsible for converting it to any platform that can run the CLR.
The programmer is removed several layers from the hardware and doesn’t
really need to know what platform his/her code is running on. One additional
service of the CLR is handling bad code. User have probably heard stories of
rogue code that overran buffers and trashed a machine, killing all other programs
along with it. By design, this cannot happen with code written in Visual Basic.net.
System Namespace
The System namespace includes all classes that represent the base data types
used by all Visual Basic.net applications. In .net, all of the base data types are
Object, Byte, Char, Array, and so on. Many of these correspond to the data type in
classic VB.
In addition to the base data types, the System namespace contains nearly 100
classes that provide functionality ranging from handling exceptions and forming
delegates to dealing with the core run-time concepts such as application domains
and the automatic memory manager. The System namespace also contains 25
second-level namespaces.
FEATURES OF SQL SERVER
A database management, or DBMS, gives the user access to their data and helps
them transform the data into information. Such database management systems

include dBase, paradox, IMS, SQL Server and SQL Server. These systems allow
users to create, update and extract information from their database.
A database is a structured collection of data. Data refers to the
characteristics of people, things and events. SQL Server stores each data item in
its own fields. In SQL Server, the fields relating to a particular person, thing or
event are bundled together to form a single complete unit of data, called a record
(it can also be referred to as raw or an occurrence). Each record is made up of a
number of fields. No two fields in a record can have the same field name.
During an SQL Server Database design project, the analysis of your business
needs identifies all the fields or attributes of interest. If your business needs
change over time, you define any additional fields or change the definition of
existing fields.
SQL SERVER TABLES
SQL Server stores records relating to each other in a table. Different tables
are created for the various groups of information. Related tables are grouped
together to form a database.
PRIMARY KEY
Every table in SQL Server has a field or a combination of fields that
uniquely identifies each record in the table. The Unique identifier is called the
Primary Key, or simply the Key. The primary key provides the means to
distinguish one record from all other in a table. It allows the user and the database
system to identify, locate and refer to one particular record in the database.
RELATIONAL DATABASE
Sometimes all the information of interest to a business operation can be
stored in one table. SQL Server makes it very easy to link the data in multiple
tables. Matching an employee to the department in which they work is one
example. This is what makes SQL Server a relational database management

system, or RDBMS. It stores data in two or more tables and enables you to define
relationships between the table and enables you to define relationships between the
tables.
FOREIGN KEY
When a field is one table matches the primary key of another field is referred
to as a foreign key. A foreign key is a field or a group of fields in one table whose
values match those of the primary key of another table.
REFERENTIAL INTEGRITY
Not only does SQL Server allow you to link multiple tables, it also
maintains consistency between them. Ensuring that the data among related tables
is correctly matched is referred to as maintaining referential integrity.
DATA ABSTRACTION
A major purpose of a database system is to provide users with an abstract
view of the data. This system hides certain details of how the data is stored and
maintained. Data abstraction is divided into three levels.
Physical level: This is the lowest level of abstraction at which one describes how
the data are actually stored.
Conceptual Level: At this level of database abstraction all the attributed and what
data are actually stored is described and entries and relationship among them.
View level: This is the highest level of abstraction at which one describes only
part of the database.
ADVANTAGES OF SQL
 Redundancy can be avoided
 Inconsistency can be eliminated
 Data can be Shared
 Standards can be enforced

 Security restrictions ca be applied
 Integrity can be maintained
 Conflicting requirements can be balanced
 Data independence can be achieved.

SYSTEM STUDY
System Analysis is the process of gathering and interpreting facts,
diagnosing problems and using the information to recommend improvements to the
existing system. The major steps are defining Software Requirements, studying the
present system to verify the problem and defining the performance expected by the
management team to meet the user expectations.
EXISTING SYSTEM
In this existing system the centre examinations are conducted by a written
theme. In that method, the Examiner as well as the students was insisted to make
more efforts. The Examiner has to prepare questions in papers & make them
multiple copies by using carbon papers (or) Xerox machines. The question papers
are saved in the files. Even though the Examiner was so aware in saving his
question papers they may decay in the course of time. The students should answer
the questions & to submit the answer sheets. The answer sheets are collected in a
file by the Examiner.
DRAWBACKS
 The answer sheets may be missed.
 The Examiner has to correct the papers & the results are announced to the
students later.
 This method of conducting Examination takes more time & efforts of both
the students & Examiner.
 In addition to these consequences in the course of time, the question &
answer sheet may be decayed.

PROPOSED SYSTEM
Online Examination is a project work of conducting Exams to a group of
students in a specified centre. The Examiner arranged the questions in the system.
The examiner may add more students (or) Examiners for attending and conducting
Examination respectively. He may also modify, delete the students & examiners
from the student’s list & examiners list.
ADVANTAGES
 The examiner may also add subjects & questions if necessary. The
unnecessary (or) erroneous questions may be deleted (or) altered from the
set of questions by the Examiner. The marks for the correct answers will be
updated simultaneously.
 The specified students mark will be displayed at the end. The additional
advantages are that the students cannot copy from the neighbors. By using
the previous button, they may change the answer what they had selected
already.
 This type of conducting examination will save time and effort of both the
students & the examiners.

DATABASE DESIGN
A table is a collection of data about a specific topic. For example a table can
contain data about customers, suppliers and the products. Tables organize data
into columns (called fields) and rows (called records).
The term database design can be used to describe many different parts of the
design of an overall database system. Principally, and most correctly, it can be
thought of as the logical design of the base data structures used to store the data. In
the relational model these are the tables and views. In an object database the
entities and relationships map directly to object classes and named relationships.
However, the term database design could also be used to apply to the overall
process of designing, not just the base data structures, but also the forms and
queries used as part of the overall database application within the database
management system (DBMS).
Conceptual schema
Once a database designer is aware of the data which is to be stored within
the database, they must then determine where dependency is within the data.
Sometimes when data is changed you can be changing other data that is not visible.
For example, in a list of names and addresses, assuming a situation where multiple
people can have the same address, but one person cannot have more than one
address; the name is dependent upon the address, because if the address is
different, then the associated name is different too. However, the other way around
is different. One attribute can change and not another.
Physical database design
The physical design of the database specifies the physical configuration of
the database on the storage media. This includes detailed specification of data
elements, data types, indexing options and other parameters residing in the DBMS

data dictionary. It is the detailed design of a system that includes modules & the
database's hardware & software specifications of the system.
INPUT DESIGN
Input design must be in such a way that it must control the amount of input,
avoid delay, etc. It must be simple. The input design must ensure user-friendly
screen, with simplicity, providing ease of viewing & entering the data. Every input
data is validating. If the data is not valid, proper error message are displayed.
The main objective of designing input focus on:
 Controlling the amount of input required.
 Avoiding delayed response.
 Controlling errors.
 Keeping process simple.
 Avoiding errors.
Needless to say, therefore, that the input data is the lifeblood of a system and
have to be analyzed and designed with at most case and consideration. The
decisions made during the input design are
 To provide cost effective method of input
 To achieve the highest possible level of accuracy
 To ensure that input is understand by the user.
System analysis decide the following input design details like, what data to
input, what medium to use, how the data should be arranged or coded, data items
and transaction needing validations to detect errors and at last the dialogue to guide
user in providing input.

OUTPUT DESIGN
Computer output is the most important and direct source of information to
the user. Efficient intelligible output design should improve the system relationship
with the user and help in decision making. Output design generated refers to the
results generated by the system. The output of a system can take many forms. The
most common are screen displays, printed forms and graphical drawings.
The output a screen displays the result for each image process in the project
and also shows the newly draw images and images are presented already in the
system. These screens are being built using Visual Basic Tools. The output screens
are designed in such a way that they generate the results necessary for the
organization.
The normal procedure in developing a system is to design the output in
detail first and then move back to the input. The output will be in the form of
views. The output from the system is required to communicate the result of
processing to the users. They are also used as the permanent copy for later
verifications.
Output Design Consideration
The purpose of outputs has been understood and the efficiency of
information contained should be analyzed and conformed. Then the output have
been defined in terms of
 Name of the Output.
 Content
 Format

 Frequency
SYSTEM TESTING AND IMPLEMENTATION
SYSTEM TESTING
Testing is an integral part of any system development life cycle. Insufficient
and untested applications may trend to crash and result in loss of economic and
manpower investment besides user’s dissatisfaction and downfall of reputation.
Software testing can be looked upon as one among the many process, an
organization performs, and that provides the last opportunity to correct any flaws
in the developed system. Software testing includes selecting test data that have
more probability of giving errors.
The first step in system testing is to develop a plan that tests all aspects of
the system. Completeness, correctness, reliability and maintainability of the
software are to be tested for the best quality assurance that the system meets the
specification and requirements for its intended use and performance. System
testing is the most useful practical process of executing a program with the implicit
intention of finding errors that make the program fails.
System testing is done in three phases
 Unit testing
 Integration testing
 Validation testing

UNIT TESTING
The procedure level testing is made first. By giving improper inputs, the
errors occurred are noted and eliminated. Then the web form level testing is made.
For example, storage of data to the table in the correct manner.
In the company as well as seeker registration form, the zero length username
and password are given and checked. Also the duplicate username is given and
checked. In the job and question entry, the button will send data to the server only
if the client side validations are made.
INTEGRATION TESTING
Testing is done for each module. After testing all the modules, the modules
are integrated and testing of the final system is done with the test data, specially
designed to show that the system will operate successfully in all its aspects
conditions. Thus the system testing is a confirmation that all is correct and an
opportunity to show the user that the system works.
VALIDATION TESTING
The final step involves Validation testing, which determines whether the
software function as the user expected. The end-user rather than the system
developer conduct this test most software developers as a process called “Alpha
and Beta Testing” to uncover that only the end user seems able to find. The
compilation of the entire project is based on the full satisfaction of the end users.

MODULES
 Login Module
 Question upload Module
 Examination Module
 Report Module
DESCRIPTION
LOGIN MODULE
Login is the main process of this system. It can have all the privileges to do
anything in this system. Admin can get the information regarding upload questions,
reports and various sources.
QUESTION UPLOAD MODULE
In this module adding students, faculty members and administrator images to the
system. Which available for student to ensure that exam. It Allow the faculty
member to control for enable or disable the exam for his students. that saves the
time to rewrite the questions for future course.
EXAMINIATION MODULE
In this module that saves the time to enter a question in the on-line system, if
the teacher needs not the direct answers. Make the order of questions as random, or
select random questions from a set of questions.
REPORT MODULE

The institute while conducting online examinations. they can give any
available exam at any available center as per his/her choice. the results of the
online exam will help a company or institute to list out the outstanding exam takers
all over the country.
Reports can be generated by the admin for various purposes. Based on the
reports admin take decisions of the system. Different kinds of reports can be
generated they are

SYSTEM IMPLEMENTATION
Implementation is process of converting a new or revised system design into
an operational one. The first task is implementation planning that is deciding on
the methods and time scale to be adopted. The proper implementation involves
conversion of existing clerical files to computer media and hence these files as they
are get converted. Then the actual changeover from the existing system to the new
system takes place.
The changeover plays a vital role, which checks the developed tool for the
following requirements, and then only the developed tool will be accepted by the
users. The software has been checked with sample data. The changes being made
are as per the user requirements and will run in parallel with the manual system to
find out any discrepancies. The users also have been apprised of the ways of
handling the software, as a part of training the user personnel.
The implementation is the final stage and it is an important phase. It
involves the individual programming system testing, user training and the
operational running of developed proposed system that constitutes the application
subsystems. On major task of preparing for implementation is education of users,
which would really have taken place much earlier in the project when were being
involved in the investigation and design work. The implementation phase of
software development is concerned with translating design specifications into
source code. The user tests the developed system and changes are made according
to their needs.

In this project, the system is implemented after the testing and preparing the
document for the end user are done. During implementation of the jewellery loan
management system, the information about with stone and without stone, it works
properly. The error is identified and again the system tested. Finally the system
implemented successfully.

CONCLUSION
All the objectives of this online examination system are satisfied. The
intermediate reports can be used for verification, if necessary in future. The system
has been tested with sample data, with original data and the system is found to run
well.
The concern in which the proposed system will be implemented will find it
more efficient. The atmosphere has been made more efficient and interactive. The
functioning of the system can be further enhanced in a number of ways, though an
attempt has been made for security and high reliability.
The newly developed system had simplified the operation for conducting
online examination. It is portable and flexible for further enhancement.

SCOPE FOR FUTURE ENHANCEMENTS
Every application has its own merits and demerits. The project has covered
almost all the requirements. Further requirements and improvements can easily be
done since the coding is mainly structured or modular in nature. Changing the
existing modules or adding new modules can append improvements. This
computerized method is a well-suited application for the real time business
activities. It posses many robust features, still it can be expanded for additional
features.
The requirements may change when technology and time changes. When the
technology and time changes the system has to be enhanced, this system itself
provides us the facility to perform some additional features. Every application has
its own merits and demerits. The project has covered almost all the requirements.
Further requirements and improvements can easily be done since the coding is
mainly structured or modular in nature. Changing the existing modules or adding
new modules can append improvements.
