1.INTRODUCTION
1.1 PROJECT SUMMERY
In Virtual Education System connects the people who want to
learn and who want to teach. It helps people who cannot go to the
school or college to study like girls in backward area and physically
disable people.
There are three main user of the system.
Admin
Faculty
Student
Admin will log in the system in the log in menu and the system
will direct this user to admin interface. In this module there will be
options to create user and course into the database and which
student allocated to whom. He approves user and assure user about
registration. These are the full responsibilities of admin.
Faculty can be a user of the system after passing the exam taken
by the VES. He will log the system in the log in menu and the system
will direct this user to faculty interface. In this module there will be
option to upload material like ppt, pdf, and video.
Student can be a user of system by registration into system
student can select one or more subjects. He can study the as per his
convenience. Appear for test, View progress report and participate in
extra-curricular activates online.

1.2 .1 SCOPE OF THE PROJECT
The growing popularity of Internet and e-learning introduced
new terms to education, such as “Virtual Education System”. May be
in the near future students will not go to anywhere in order to take
their studies.
The concept “Virtual Education System” enables users to learn
from anywhere through Internet and provides a learning experience.
This project is intended to give both teacher and student the ability to
do their jobs effectively and efficiently without even leaving their
places.
By this solution we aimed to meet the expectations of both
students and faculties.
1.2.2 OBJECTIVE OF THE PROJECT
The main objective of VES is to provide an online learning
experience to the registered student of the portal. The registered
student students and faculties can also interact with each other thus
providing a healthy and friendly environment to learn while not
physically in the lecture hall. Some of the advantages of the VES are.
Removal of geographical barriers. (Anywhere learning)
Quicker to organize.
One to one communication.

1.3 HARDWARE AND SOFTWARE TECHNOLOGY
SOFTWARE TECHNOLOGY
APACHE TOMCAT7.0
Apache Tomcat is an open source software implementation of
the Java Servlet and JavaServer Pages technologies. The Java
Servlet and JavaServer Pages specifications are developed under
the Java Community Process.
Apache Tomcat is developed in an open and participatory
environment and released under the Apache License version 2.
Apache Tomcat is intended to be a collaboration of the best-of-
breed developers from around the world.
Apache Tomcat powers numerous large-scale, mission-critical
web applications across a diverse range of industries and
organizations.
NETBEANS 7.1
NetBeans is an integrated development environment (IDE) for
developing primarily with Java, but also with other languages, in
particular PHP, C/C++, and HTML5. It is also an application
platform framework for Java desktop applications and others.
The NetBeans IDE is written in Java and can run on Windows,
OS X, Linux, Solaris and other platforms supporting a
compatible JVM.
The NetBeans Platform allows applications to be developed from
a set of modular software components called modules.
Applications based on the NetBeans Platform (including the
NetBeans IDE itself) can be extended by third party developers.

WINDOWS 7 ULTIMATE
Windows7 is a major release of the Microsoft Windows, is
available in six different editions (Starter, Home Basic, Home
Premium, Professional, Enterprise and Ultimate). Only Home
Premium, Professional, and Ultimate are widely available at
retailers. The other editions focus on other markets, such as
the developing world or enterprise use. All editions support 32-
bit IA-32 CPUs and all editions except Starter support 64-
bit x64 CPUs. (64-bit installation media is not included in Home-
Basic edition packages, but can be obtained separately from
Microsoft).
According to Microsoft, the features for all editions of Windows 7
are stored on the machine, regardless of which edition is in use.
Users who wish to upgrade to an edition of Windows 7 with more
features can then use Windows Anytime Upgrade to purchase the
upgrade and to unlock the features of those editions.
OVERVIEW OF JAVA
Java programming language was originally developed by Sun
Microsystems which was initiated by James Gosling and released
in 1995 as core component of Sun Microsystems' Java platform
(Java 1.0 [J2SE]).
Sun Microsystems has renamed the new J2 versions as Java SE,
Java EE and Java ME respectively. Java is guaranteed to be Write
Once, Run Anywhere.
Java is:
Object Oriented: In Java, everything is an Object. Java can be
easily extended since it is based on the Object model.
Platform independent: Unlike many other programming
languages including C and C++, when Java is compiled, it is not
compiled into platform specific machine, rather into platform

independent byte code. This byte code is distributed over the web
and interpreted by virtual Machine (JVM) on whichever platform it
is being run.
Simple: Java is designed to be easy to learn. If you understand
the basic concept of OOP Java would be easy to master.
Secure: With Java's secure feature it enables to develop virus-
free, tamper-free systems. Authentication techniques are based on
public-key encryption.
Architectural-neutral: Java compiler generates an architecture-
neutral object file format which makes the compiled code to be
executable on many processors, with the presence of Java runtime
system.
Portable: Being architectural-neutral and having no
implementation dependent aspects of the specification makes Java
portable. Compiler in Java is written in ANSI C with a clean
portability boundary which is a POSIX subset.
Robust: Java makes an effort to eliminate error prone situations
by emphasizing mainly on compile time error checking and
runtime checking.
Multithreaded: With Java's multithreaded feature it is possible
to write programs that can do many tasks simultaneously. This
design feature allows developers to construct smoothly running
interactive applications.
Interpreted: Java byte code is translated on the fly to native
machine instructions and is not stored anywhere. The
development process is more rapid and analytical since the linking
is an incremental and light weight process.
High Performance: With the use of Just-In-Time compilers, Java
enables high performance.
Distributed: Java is designed for the distributed environment of
the internet.

Dynamic: on run-time Java is considered to be more dynamic
than C or C++ since it is designed to adapt to an evolving
environment. Java programs can carry extensive amount of run-
time information that can be used to verify and resolve accesses
to objects.
MYSQL SERVER
The MySQL database has become the world's most popular open
source database because of its high performance, high reliability
and ease of use. It is also the database of choice for a new
generation of applications built on the LAMP stack (Linux, Apache,
MySQL, PHP / Perl / Python.) Many of the world's largest and
fastest-growing organizations including Facebook, Google, Adobe,
Alcatel Lucent and Zappos rely on MySQL to save time and money
powering their high-volume Web sites, business-critical systems
and packaged software.
MySQL runs on more than 20 platforms including Linux,
Windows, Mac OS, Solaris, IBM AIX, giving you the kind of
flexibility that puts you in control. Whether you're new to database
technology or an experienced developer or DBA, MySQL offers a
comprehensive range of database tools, support, training and
consulting services to make you successful.

2. SYSTEM ANALYSIS
2.1. STUDY OF CURENT SYSTEM
In current system student go to School and College for getting the
knowledge.
In current system all things are done manually.
In current system class and projector are occupied.
In current system student go to School and College so the
traveling cost is more.
In current system student go to School and College so the wasting
the time is more.

2.2 PROBLEMS AND WEEKNESS OF CURRENT SYSTEM
In the current system students go to school and college for
getting the knowledge.
In the current system students travel from one place to
another place for getting the knowledge so it is very time
consuming.
In the current system students pays high fees in the school
and college for the knowledge.
In the current system students travel from one place to
another place for getting the knowledge so travelling cost is
high.
In the current system particular school and college occupied
projectors and rooms.

2.3 REQUIREMENT OF NEW SYSTEM
The quality of VES is defined by student success. Students
are coming back to us time and time again. Success needs to
be judged not just at the time, but as students move forward
into careers or further education. We judge our quality by
student retention, completion/passage, and re-enrollment.
“Quality is high quality courses, highly trained instructors,
support provided for students.
VES should be comprehensive, reliable, and user-friendly
online learning systems. It should be designed from the
ground up to meet the exact requirements of students and
faculties. It brings students right to connect 24 hours a day
from any Internet connection.
It should be cost effective. User can learn the courses with-
out paying the fees.Virtual Education is a free online
educational program to promote communication,
collaboration and understanding among the student around
the world.
In the propose system students learn at any place so the
student get free environment.
In the propose system at learning time student should be
able to ask their query and get their solution at that time.
In our propose system provide One to Many Communications
between the faculty and student.

2.4 FEASIBILITY STUDY
Feasibility Study is the test of the system proposal according to its work
ability, impact on the current system, ability to meet the needs of the current
users and effective use of the resources.
Its main objective is not to solve the problem, but to acquire its scope. It
focuses on following:
Meet user requirements
Best utilization of available resources
Develop a cost effective system
Develop a technically feasible system
There are three aspects in the feasibility study:
Technical Feasibility
Economical Feasibility
Operational Feasibility
2.4.1 TECHNICAL FEASIBILITY
The technical issues usually raised during the feasibility stage of
the investigation include following:
The necessary technology must be existed to do what is suggested.
The proposed equipment must have the technical capacity to hold
the data required to use the new system.

There must be technical guarantees of accuracy, reliability ease of
access and data security.
All the functional and non-functional requirements of our Virtual
Education is developed in the J2EE (NetBeans 7.0 as the front-end
and MySql as back-end).
The development of the system is technically feasible as the various
technological needs for the development and deployment are
fulfilled.
2.4.2 ECONOMICAL FEASIBILITY
Issues to be studied are, whether the new system is cost effective
or not? The benefits in the form of reduced cost?
This Web based Virtual Education is economically feasible. As the
hardware was installed from quite beginning, the cost on project
of hardware is low.
Similarly, the software loaded for this project was used for many
other applications. The software cost was under budget.
As student trainees were developing the application, there were no
major personnel costs associated. Moreover, the technical
requirements were already available so there was no further
expenditure for buying software packages.

Here, this system is beneficial for the organization as work cost will
be decreased by developing the project.
2.4.3 OPERATIONAL FEASIBILITY
Issues to be studied are, is there sufficient support for management
and users? Is the current method acceptable to users? Will the
proposed system cause any harm?
This Web based Virtual Education is operationally feasible. The user
just needed to have the basic knowledge of computers.

3. MANAGEMENT
3.1 PROJECT DEVELOPMENT APPROACH
I have used the iterative model for software development
lifecycle.
An iterative life cycle model does not attempt to start with a full
specification of requirements. Instead, development begins by
specifying and implementing just part of the software, which can then
be reviewed in order to identify further requirements. This process is
then repeated, producing a new version of the software for each cycle
of the model.

ADVANTAGES OFITERATIVE MODEL:
In iterative model we can only create a high-level design of
the application before we actually begin to build the product
and define the design solution for the entire product. Later on
we can design and built a skeleton version of that, and then
evolved the design based on what had been built.
In iterative model we are building and improving the product
step by step. Hence we can track the defects at early stages.
This avoids the downward flow of the defects.
In iterative model we can get the reliable user feedback.
When presenting sketches and blueprints of the product to
users for their feedback, we are effectively asking them to
imagine how the product will work.
In iterative model less time is spent on documenting and
more time is given for designing.
DISADVANTAGES OF ITERATIVE MODEL:
Each phase of an iteration is rigid with no overlaps
Costly system architecture or design issues may arise because
not all requirements are gathered up front for the entire
lifecycle.
WHEN TO USE ITERATIVE MODEL:
Requirements of the complete system are clearly defined and
understood.
When the project is big.

3.2 RISK MANAGEMENT
3.2.1 RISK ANALYSIS
. The top five risks identified, in decreasing order of importance, were:
Insufficient human resources
Unrealistic schedule and budget
Unrealistic expectations
Incomplete requirements
Diminished window of opportunity owing to late delivery of software
Interestingly, the main conclusion of the study was that good project
management is the most effective „technique‟ for dealing with risks in IT
projects.
The sources of risk to distributed e-learning projects identified by this
study are listed below in rough order of their importance. This has been
determined in two ways:
Making a worst-case assessment of the risk in terms of the eight
categories defined above;
Using the particular experiences of current projects;

3.2 RISK PLANING
Insufficient or uncertain human resources
The human resources and time needed to create content is frequently
underestimated. Even with ready-made material, creating content is extremely
time-intensive. Also, projects cannot assume that after creation of a content
infrastructure, subject experts will be able to create e-learning content
independently - they will require guidance and support, which is likely to increase
demand for human resources both from the project team and from parent
institutions.
1 Technical limitations of solutions reached or exceeded
The technologies used by some of the projects are at the “leading edge” of
development and may not always meet prior expectations. Several of the projects
depend on technology / systems development and implementation work funded by
JISC and in a few cases a particular technology turned out not to be capable of
providing the required solution at its current stage of development
2 Poor partnership working
Some of the projects have experienced difficulties with or between project
partners. Anticipatory strategies to deal with such issues exist and can be effective.
In one case, a project anticipated issues with some of the project partners. Partner
inputs were designed and agreed in such a way that essential aspects of
development work were duplicated by more than one partner, delivering multiple,
alternative versions.
This deliberate redundancy was intended to reduce the chances that problems
with one partner‟s contribution would affect progression and outcomes of the
projects as a whole. Delayed or incomplete partner inputs could more easily be left
for later incorporation and, if not delivered to specification, the project would only
suffer to the extent that a particular developmental variant would not be part of the
project outputs. This example demonstrates a trade-off between the cost and effort
associated with redundancy, and reduction of risk impact.
3 Unrealistic expectations
The projects appear to set themselves modest and realistic expectations for
project outcomes. However, the large numbers of partners in many projects
increases the likelihood of a mismatch in expectations. Some project managers
expressed the private belief that particular partners would not deliver because they
had set their sights too high

3.3 IDENTIFICATION
Risk can be identified using following questions.
How will overseas markets affect your e-learning strategy?
How might funding council policies affect your institutions e-learning?
What type of e-learning strategy have you developed?
What are the objectives of your e-learning investment?
Does your strategy include collaboration?
How will you fund your e-learning investments?
Is the e-learning investment sustainable?
How will working practices and staff roles be affected by e-learning?
How will coordination/collaboration across different categories of staff be
achieved?
What staff skills will be required to support e-learning?
What skills will students need to develop in order to participate in e-
learning?
How centralised-decentralised are your technology support structures?
What is the impact of e-learning on organisational structures?
What structures are in place to support students in their e-learning?
Should you buy, make or use open source technologies?
Is your network infrastructure adequate?
What are the risks of Virtual and Managed Learning Environment
investments?
Are your technologies integrated and resilient?
How will you manage change?
How are your e-learning projects managed?
How do you appraise options and evaluate projects?
How is the quality of e-learning managed?
This checklist can serve as a „memory aid‟ in identifying a wide range of
issues which determine or influence actions and decisions in the project
environment.

7. LIMITATION AND FUTURE ENHANCEMENT
LIMITATION:
In virtual education system , students need a computer and a decent
Internet connection.
Studying on the Internet offers a form of interaction, but it isn't
quite the same as being in the room with somebody. For example,
some courses are based around chat rooms or message boards.
If you want study something like car repair, you'll need some
actual hands-on training. There are many subjects that can't be
studied without personal access to real-life equipment and
experience.
Some people aren't very good at self-motivation, and this can
make virtual schooling more difficult. The physical presence of a
teacher and classmates can often exert a subtle pressure that
keeps you focused.
FUTURE ENHANCEMENT:
Video Conferencing.
Session Recording.
Fees structure.
Two way communication.
