1.1 Goals And Objectives
E-COMURA promotes anytime, anyplace learning. Functionally, it allows teachers to
post messages, discuss classroom topics, assign and grade class work, share content and
materials, and network and exchange ideas with their peers. Take a peek at some of the
unique ways teachers are using E-COMURA to make their classroom a community. E-
COMURA has simply changed the way teachers teach. Now students get assignments,
ask questions, collaborate and communicate outside the confines of the school and class
room. Students can post questions on the site and teachers respond within minutes. This
has given student‘s confidence in their abilities to work hard knowing they have teachers
and their classmates to assist them. Additionally, students and teachers are connected to
many other teachers, classes and communities through E-COMURA that further assist
and expand education.

1.2 Overview of Technical Area
Agile software development refers to a group of software development methodologies
based on iterative development, where requirements and solutions evolve through
collaboration between self-organizing cross-functional teams.
Agile methods break tasks into small increments with minimal planning, and do not
directly involve long-term planning. Iterations are short time frames that typically last
from one to four weeks. Each iteration involves a team working through a full software
development cycle including planning, requirements analysis, design, coding, unit
testing, and acceptance testing when a working product is demonstrated to stakeholders.
This helps minimize overall risk, and lets the project adapt to changes quickly.
Stakeholders produce documentation as required. Iteration may not add enough
functionality to warrant a market release, but the goal is to have an available release at
the end of each iteration. Multiple iterations may be required to release a product or new
features. Software Engineering will also be exercised which will help in a resultant
library of components, the benefit of which will be reusability and fast development
Understanding .Net Frame Work
The .Net framework can be defined as a language neutral platform designed to provide a
number of rich and powerful application development tools and technologies. It has an
extensive class library that provides wide-ranging support for data access..Net framework
has an independent code execution and management environment called the Common
Language Runtime (CLR) which ensures that code is safe to run, and provides an abstract
layer on top of the operating system, which allows the elements of the .Net framework to
run on many operating systems and devices.
Microsoft SQL Server™ 2008
Microsoft SQL Server 2008 is a full-featured relational database management system
(RDBMS) that offers a variety of administrative tools to ease the burdens of database
development, maintenance and administration. In this article, we'll cover six of the more

4. 4
frequently used tools: Enterprise Manager, Query Analyzer, SQL Profiler, Service
Manager, Data Transformation Services and Books Online.
1. Language Used
The Microsoft .NET Framework is a software framework that can be installed on
computers running Microsoft Windows operating systems . It includes a large library
of coded solutions to common programming problems and a virtual machine that
manages the execution of programs written specifically for the framework.
The framework's Base Class Library provides a large range of features including user
interface, data access, database connectivity, cryptography, web application development,
numeric algorithms, and network communications. The class library is used by
programmers, who combine it with their own code to produce applications.
Programs written for the .NET Framework execute in a software environment that
manages the program's runtime requirements. Also part of the .NET Framework, this
runtime environment is known as the Common Language Runtime (CLR). The CLR
provides the appearance of an application virtual machine so that programmers need not
consider the capabilities of the specific CPU that will execute the program. The CLR also
provides other important services such as security, memory management, and exception
handling. The class library and the CLR together constitute the .NET Framework.
Version 3.0 of the .NET Framework is included with Windows Server 2008 and
Windows Vista. Version 3.5 is included with Windows 7, and can also be installed on
Windows XP and the Windows Server 2003 family of operating systems. On April 12,
2010, .NET Framework 4 was released alongside Visual Studio 2010.
Understanding .Net Frame Work
DEFINITION: The .Net framework can be defined as a language neutral platform
designed to provide a number of rich and powerful application development tools and

5. 5
technologies. It has an extensive class library that provides wide-ranging support for data
access.
.Net framework has an independent code execution and management environment called
the Common Language Runtime (CLR) which ensures that code is safe to run, and
provides an abstract layer on top of the operating system, which allows the elements of
the .Net framework to run on many operating systems and devices.
THE .NET VISION:
The .Net framework provides the foundation and the plumbing on which the Microsoft
.Net vision is built. The vision is about having a global network and open standards like
XML to make it easier for parties to exchange data and work together. Now devices will
use common languages like XML over standardized or shared protocols such as HTTP
and these devices will be running a multitude of software on various operating systems.
This is not limited to Microsoft but also to other operating systems such as sun, IBM.
The .Net framework provides the tools and the technologies needed to write applications
that can seamlessly and easily communicate over the Internet using open standards like
XML and SOAP. It also aims at solving the various problems that are faced by
developers while working on applications made using the windows DNA. It provides a
solution to problems such as registering of components and shutting down applications in
order to upgrade them.
BENEFITS OF USING .NET:
The windows platform is inherently complex and may pose several problems for
programmers. However the .Net platform is used as it provides solutions to many such
problems and offers an Internet centric platform.
The following are the benefits of using .Net platform:
1) Multiple platform Support .Net platform has been designed keeping multiple
platform support as a key feature. For version 2.0 this means that the code written

6. 6
using the .Net platform can run on all versions of Windows. i.e. Windows
98,95,NT,2000 and so on. Microsoft has included rich support for all the
platforms. Also this code shall also work on any 64-bit processor that may be
used by Microsoft later. It is also expected that .Net shall run on other platforms
like UNIX also, however it is not for sure that all functionality will be available
for the same.
2) Net as a clean start: On the windows platform, the technologies available often
depend on the programming language that they are written in, so they are very
different. Depending on the chosen programming language, these technologies
can be restrictive. The problem with this approach is that it makes the Windows
platform harder to understand. Using .Net there is just one simple object oriented
way of accessing the functionality of the .Net Framework

2.2 Survey
We have gone through the following research papers to see the developments in field of
web technology and security used for web applications
PAPER 1
Web Applications -
Spaghetti Code for the 21st Century
Abstract:
The software industry is currently in the middle of a paradigm shift. Applications are
increasingly written for the World Wide Web rather than for any specific type of an
operating system, computer or device. Unfortunately, the technologies used for web
application development today violate well-known software engineering principles.
Furthermore,they have reintroduced problems that had already been eliminated years ago
in the aftermath of the ―spaghetti code wars‖ of the 1970s. In this paper, we investigate
web application development from the viewpoint of established software engineering
principles. We argue that current web technologies are inadequate in supporting many of
these principles. However, we also argue that there is no fundamental reason for web

10. 10
applications to be any worse than conventional applications in any of these areas. Rather,
the current inadequacies are just an accidental consequence of the poor conceptual and
technological foundation of the web development technologies today.
PAPER 2
Role Based Authentication Schemes for Security Automation
Abstract—Academy Automation implies to the various different computing hardware
and software that can be used to digitally create, manipulate, collect, store, and relay
Academy information needed for accomplishing basic Operation like admissions and
registration to finance, student and faculty interaction, online library, medical and
business development. Raw data storage, electronic transfer, and the management of
electronic business information comprise the basic activities of an Academy automation
system. The main aim of this work was to design and implement a Role Based
Authentication (RBA) System wherein each user has certain roles allotted to him/her
which defines the user‘s limits and capabilities of making changes, accessing various
areas of the software and transferring/allotting these roles recursively. Strict security
measures had kept in mind while designing such a system and proper encryption and
decryption techniques are used at both ends to prevent any possibility of any third party
attacks. Further, various new age authentication techniques like OpenID and
WindowsCardSpace are surveyed and discussed to serve as a foundation for future work
in this area.

CHAPTER 3
PROBLEM DEFINITION AND
REQUIREMENT ANALYSIS

12. 12
3.1 Problem Definition
This phase describes the problems; and tries to find out the approach to solve the
problem. During problem analysis, one of the first things to do is to formulate the
problem. If you get this wrong (or skip it completely) everything you do afterwards could
be a complete waste of time and money.It's all too easy to solve the wrong problem, or
find that your eventual solution does not solve the problem fully, if at all. It all depends
on how you approach and define the problem. Before you start trying to solve a problem
it's important to study the existing system before embarking on major changes.
Consider the case like a visit to the doctor. You would be pretty worried if you told the
doctor you had a headache and the doctor immediately started merrily injecting you with
various things before even looking at you or asking you any questions. Such behavior is
likely to cause more problems than it solves, so doctors always analyze their patients -
observing, questioning, and testing before beginning any treatment.So also do problem
solvers study the system they intend to change, and the organization it's in, before they
decide what needs to be done? By thoroughly understanding a system, its operation, its
context, its strengths and weaknesses, one can better decide how to start improving it.
Determining whether a problem is worth fixing involves a feasibility study. The aim of
the feasibility study is to understand the problem and to determine whether it is worth
proceeding. You end up with a logical design that describes what the current system does,
and what the new system needs to be able to do, but does not specify how it's done.
Initially I conducted problem analysis, where I thoroughly worked out to carry out a
study for recognizing the needs (the actual problem), understanding the current system
and thereby specifying how my proposed system was better than the existing system. I
just tried to find out what the problem was and not how to handle it!

13. 13
3.2 Requirements
The software requirement specification is produced at the culmination of the analysis
task. The function and performance allocated to software as part of system engineering
are refined by establishing a complete information description, a detailed functional
description, a representation of system behavior, an indication of performance
requirement and design constraints appropriate validation criteria, and other information
pertinent to requirement.
The introduction to software requirements specification states the goals and objectives of
the software, describing it in the context of the computer based system. The Information
Description provides a detailed description of the problem that the software must solve.
Information content, flow and structure are documented.
A description of each function required to solve the problem is presented in the
Functional Description. Validation Criteria is probably the most important and ironically
the most often neglected section of the software requirement specification. Software
requirement specification can be used for different purpose.
A main purpose of the product specification is to define the need of the product‘s
user. Some times, the specification may be a part of a contract sign between the
producer and the user. It could also form part of the user manuals. A user‗s needs
are sometimes not clearly understood by the developer. If this is the case, a careful
analysis – involving much interaction with the user should be devoted to reaching a
clear statement of requirements, in order to avoid possible misunderstandings.
Sometimes, at the beginning of a project, even the user has no clear idea of what
exactly the desired product is. Think for instance of user interface , a user with no
previous experience with computer products may not appreciate the difference
between , say menu driven interaction and a command line interface. Even an exact
formation of system functions and performance may be missing an initial
description produced by an experienced user.

3.3 System Specification
System analysis is the process of studying the business processors and procedures,
generally referred to as business systems, to see how they can operate and whether
improvement is needed. This may involve examining data movement and storage,
machines and technology used in the system, programs that control the machines, people
providing inputs, doing the processing and receiving the outputs.
Investigation Phase
The investigation phase is also known as the fact-finding stage or the analysis of the
current system. This is a detailed study conducted with the purpose of wanting to fully
understand the existing system and to identify the basic information requirements.
Various techniques may be used in fact-finding and all fact obtained must be recorded. A
thorough investigation was done in every effected aspect when determining whether the
proposed system is system is feasible enough to be implemented.
Investigation
As it was essential for us to find out more about the present system, we used the
following methods to gather the information: -
1. Observation: - Necessary to see the way the system works first hand.
2. Document sampling: - These are all the documents that are used in the system. They
are necessary to check all the data that enters and leaves the system.
3. Questionnaires: - These were conducted to get views of the other employees who are
currently employed in the system.

19. 19
Analysis of The Investigation
Strengths of the System
1. No complex equipment: - The equipment that is used is very simple and no
special skills have to be mastered to be able to operate the system. Therefore no
training is required for the employees.
2. Low cost: - There is little money spent in maintaining the present system other
than buying the necessary office equipment and the ledgers.
Constraints and Limitations
The constraints and limitation within a system are the drawbacks that occur during the
implementation of the system. These limitations and constraints can crop up in almost
every system; the most important fact is to find a way to overcome these problems.
Software design is the first of three technical activities – design, code generation, and test
that are required to build and verify the software. Each activity transforms information in
manner that ultimately results in validated computer software.
The design task produces a data design, an architectural design, an interface design and
component design. The design of an information system produces the details that clearly
describe how a system will meet the requirements identified during system analysis. The
system design process is not a step by step adherence of clear procedures and guidelines.
When I started working on system design, I face different types of problems; many of
these are due to constraints imposed by the user or limitations of hardware and software
available. Some times it was quite difficult to enumerate that complexity of the problems
and solutions thereof since the variety of likely problems is so great and no solutions are
exactly similar however the following consideration I kept in mind during design phased.

20. 20
CHAPTER 4
DESIGN AND IMPLEMENTATION

21. 21
4.1 Introduction
System Design is the process of planning a new system to replace existing one. If the
analysis means ‗what‘ the system should do, then design specifies ‗how‘ to accomplish
the objectives. The design of the system uses information gathered as basis and produces
details that state how the system will meet the requirements identified during the analysis
phase. Design is very crucial in the whole development cycle. The logical system of the
product is developed in this phase. Design will serve as a blueprint for a system and helps
detect problems before errors or problems are built into the final system. Professionals
create a system design, but must review their work with the users to ensure the design
meets user‘s needs. The exceptional (or foolish) programmer might begin coding
without a good design. Programmers who do so may find themselves going back to
modify pieces of code they've already written as they move through the project. With a
good design, the likelihood of this happening will be reduced dramatically. The end result
is a program that will behave in the way it was intended, and will generally have with a
shorter overall program development time.
When I decided to start with the designing phase for my project, I had two design phases
that I tempted to follow. They were:
 Module Design
 Detailed Design

22. 22
4.2 Functional Decompositions
Module Design
This phase involves understanding the modules required for the project. However this
understanding is confined only to get an overview of the system design and then
preparing for the detailed designing for the project. During this sub-phase of system
designing, I tried to create an understanding about how a module would work. For this I
developed few pictorial representations just trying to picture design for the overall
system. It was just limited to creating a blueprint of the entire system design.
Primarily, in this phase I focused on deciding which modules are needed for the system,
the specifications for these modules and how they are related so that after combining
them I could attain the desired results.
MODULES OF THE PROJECT
 Registration and login
 Student
 Teacher
 Admin
 Each panel has three layers



23. 23
Registration: In this module, we will register different users to have a secure navigation
through documents submitted and shared by users. The registration process is made for
the trusted set of users. This is ensured by assigning every user the unique username and
password to login into the account and maintain their documents, share them and access
from anywhere.
Student:will register and login using id.join a group under a teacher can be part of
multiple groups but through different id
Teacher:register and login.create groups and add students.allot assignments and
quizzes.both teacher and students have online storage space.
Admin:has the control over the site.responsible for adding colleges and countries.
DETAILED DESIGN
The internal logic and working of each module is described in the system design is
decided in this phase. And the module logic is described in high level language. Data
structure and algorithmic design of each and every modulle are also defined in this phase.
These are part of the structured analysis, the set of techniques and graphical tools that
allow the analyst to develop a new kind of system specification that are easily
understandable to the user. It is a way to focus on function rather than physical
implementation. The traditional approach focuses on the cost/benefit analysis, feasibility
analysis, project management, hardware and software section and personal considerations
in contrast. Structured analysis considers new goals and structured tools for analysis.
There are different tools for structured system analysis of which DATA FLOW
DIAGRAMS are very important.
Now we will see algorithmic representations of each module through flowcahrts that
describe information flow in the modules. Then we will try to describe flow of data

24. 24
using the Data Flow Diagrams that completely picture out the data flow through the
client, proxy and the web server.
Using the DFD‘s and Flowcharts the internal logic and working of each module has been
specified. Algorithmic design of each module has been defined in this part of designing.
4.3 Different Design Options
DATA FLOW DIAGRAMS
It is a way of expressing system requirement in a graphical form; this leads to a
modular design. It is also known as bubble chart, has the purpose of clarifying system
requirements and identifying major transformations that will become program in
system design. So it is the starting point of the design phase that functionally
decomposes the requirement specifications down to the lowest level of details. A
DFD consist of a series of bubbles joined by lines. The bubbles represent data
transformation and the lines represent data flows in the system.
DFD SYMBOLS:
= Source or Destination of data
= Data flow
= Process that transform data flow

25. 25
= Store Data
BUSINESS LOGIC LAYER:
This layer consist of DLL (dynamic link library) naming Class Library Class1 having
namespace nsnetdocs and one class naming clscon for connection with sqlserver database
and various interfaces naming int-tablename having property declaration for each field in
the respective table, class naming 18 property class naming cls-tablename-prp which
inherit its respective interface for definition of each property declared in the interface,
class naming 18 methods class naming cls-tablename which inherit class clscon for
definition of methods like : save_rec(), update_rec(), delete_rec(), display_rec(),
find_rec() etc. methods.
Dynamic Link Library:
Compiled class
 Reusable Scope
 Multiple application
 No Graphical user interface
 In process component
 Self described
It contains following:
1. Interfaces
2. Main Classes
PRESENTATION LAYER:

26. 26
Presentation layer consists of web pages which include:
MASTER PAGES:
1. Master Page is Common Template that can be implemented on more than one Page.
We can make
changes whenever needed.
2. Master page extension is. Master
3. It can never be start up page.
4. We can create properties, methods, classes in master pages.
5. Multiple master pages can be there in single application.
CONTENT PAGES:
1. Content pages are web pages which can be made as startup page.
2. Content page extension is .aspx
3. Multiple content pages can be there in single master page
ENTITY – RELATIONSHIP MODEL:
As a database designer, one should use an Entity Relationship (ER) diagram as a tool
to build the logical database design of a system. An ER diagram represents the
following three elements:
Entities: An entity is an object with a distinct set of properties that is easily
identified.
Attributes: An attribute is a property of an entity that differentiates it from other
entities and provides information about the entity.

27. 27
Relationships: A relationship is a crucial part of the design of database.

4.5 IMPLEMENTATION
Implementation is the stage in the project where the theoretical design is turned into the
working system and is giving confidence to the new system for the users i.e. will work
efficiently and effectively. It involves careful planning, investigation of the current
system and its constraints on implementation, design of method to achieve the change
over, an evaluation, of change over methods. A part from planning major task of
preparing the implementation is education of users. The more complex system is
implemented, the more involved will be the system analysis and design effort required
just for implementation. An implementation coordinating committee based on policies of
individual organization has been appointed. The implementation process begins with
preparing a plan for the implementation for the system. According to this plan, the
activities are to be carried out, discussions may regarding the equipment has to be
acquired to implement the new system

CHAPTER 5
TESTING AND DEPLOYMENT

44. 44
5.1 Verification
The basic goal of the software development process is to produce software that has no
errors or very few errors. In an effort to detect errors soon after they are introduced, each
phase ends with verification activity such as a review. As testing is the last phase before
the final software is delivered, it has the enormous responsibility of detecting any type of
error that may in the software. A software typically undergoes changes even after it has
been delivered. And to validate that a change has not affected some old functionality of
software regression testing is performed
Levels Of Testing:
The basic levels of testing are unit testing, integration testing and system and acceptance
testing. These different levels of testing attempt to detect different types of faults.
Client Needs Acceptance Testing
Requirements System Testing
Design Integration Testing
Code Unit Testing
Table 5.1 levels of testing
Overview of Testing
1. Testing: Testing involves executing the program (or part of it) using sample data and
inferring from the output whether the software performs correctly or not. This can be
done either during module development (unit testing) or when several modules are
combined (system testing).
2. Defect Testing: Defect testing is testing for situation where the program does not meet
its functional specification. Performance testing tests a system's performance or reliability
under realistic loads. This may go some way to ensuring that the program meets its non-
functional requirements.

45. 45
3.Debugging: Debugging is a cycle of detection, location, repair and test. Debugging is a
hypothesis testing process. When a bug is detected, the tester must form a hypothesis
about the cause and location of the bug. Further examination of the execution of the
program (possible including many returns of it) will usually take place to confirm the
hypothesis. If the hypothesis is demonstrated to be incorrect, a new hypothesis must be
formed. Debugging tools that show the state of the program are useful for this, but
inserting print statements is often the only approach. Experienced debuggers use their
knowledge of common and/or obscure bugs to facilitate the hypothesis testing process.
After fixing a bug, the system must be reset to ensure that the fix has worked and that no
other bugs have been introduced. This is called regression testing. In principle, all tests
should be performed again but this is often too expensive to do.
Test Planning
Testing needs to be planned, to be cost and time effective. Planning is setting out
standards for tests. Test plans set out the context in which individual engineers can place
their own work. Typical test plan contains:
Overview of testing process
1. Requirements trace ability (to ensure that all requirements are tested)
2. List of item to be tested
3. Schedule
4. Recording procedures so that test results can be audited
5. Hardware and software requirements
6. Constraints
Overview of Testing Strategies

46. 46
Large systems are usually tested using a mixture of strategies. Different strategies may be
needed for different parts of the system or stages of the process.
1. Top-down testing: This approach tests high levels of system before detailed
components. This is appropriate when developing the system top-down and is
likely to show up structural design errors early (and therefore cheaply). But this
often has advantage that a limited, working system is available early on.
Validation (as distinct from verification) can begin early. Its disadvantage is that
stubs need to be generated (extra effort) and might be impracticable if component
is complex (e.g. converting an array into a linked list; unrealistic to generate
random list; therefore end up implementing unit anyway). Test output may be
difficult to observe (needs creation of artificial environment). This is not
appropriate for OO systems (except within a class).
2. Bottom-up testing: This is opposite of top-down testing. This tests low-level
units then works up the hierarchy. Its advantages and disadvantages mirror those
of top-down testing. In this testing there is need to write test drivers for each unit.
These are as reusable as the unit itself. Combining top-down development with
bottom-up testing means that all parts of system must be implemented before
testing can begin, which does not accord with incremental approach discussed
above. Bottom-up testing is less likely to reveal architectural faults early on.
However, bottom-up testing of critical low-level components is almost always
necessary. Appropriate for OO systems.
3. Stress testing: Tests system's ability to cope with a specified load (e.g.
transactions per second). Tests should be planned to increase load incrementally.
This type of testing goes beyond design limit until system fails (this test is
particularly important for distributed systems like checking degradation of
performance a s network traffic increases).
4. Back-to-back testing: Comparison of test results from different versions of the
system (e.g. compare with prototype, previous version or different configuration).
Process – Run first system, saving test case results. Run second system, again
saving its results. Compare result files. The key point to be noted is that no

47. 47
difference does not mean no bugs. Both systems may have made the same
mistake.
5. Defect testing: A successful defect test is a test that causes the system to behave
incorrectly. Defect testing is not intended to show that a program meets its
specification. If tests do not show up defects it may mean that the tests are not
exhaustive enough. Exhaustive testing is not always practically applicable. Subset
has to be defined (this should be part of the test plan, not left to the individual
programmer).
5.2 Validation
You validate a program by checking it against the published user or system requirements.
System testing and integrity testing are validation tests.
Integration Testing: The next level testing that was performed is often referred to as
integration testing. During this phase many unit tested modules were combined into
subsystems, which were then tested. The goal here was to see if modules can be
integrated properly. Here the emphasis was on testing interfaces between different
constituent modules of system.
Test Case Design
The primary objective of test case design is to derive a set of tests that have the highest
likelihood of uncovering errors in software. The test case specification is the major
activity in the testing process. Careful selection of test cases that satisfy the criterion on
approach specified is essential for proper testing. Various characteristics of test cases that
are required for portal are:
1. A good test has a high probability of finding an error.
2. A good test is not redundant.
3. A good test should be ―Best of Breed‖.
4. A good test should be neither too simple not too complex.

48. 48
Structure Of Test Case
A formal written test case can be divided into three main parts:
Information
Information consists of general information about the test case such as a case identifier,
case creator info, test case version, formal name of the test case, purpose or brief
description of the test case and test case dependencies. It should also include specific
hardware and software requirements (if any) and setup or configuration requirements.
Activities
This part consists of the actual test case activities such as the environment that should
exist during testing, activities to be done at the initialization of the test, activities to be
done after test case is performed, step-by-step actions to be done while testing and the
input data that is to be supplied for testing.
Results
Results are the outcomes of a performed test case. Result data consists of information
about expected results, which is the criteria necessary for the program to pass the test and
the actual recorded results.

CHAPTER 6
CONCLUSION AND FUTURE
ENHANCEMENTS

51. 51
6.1 Summary of work done
Towards the end of my project, we would like to say that the target which was initially
setup, was achieved to a good extent. The project made me realize the significance of
developing software for client, where all the eventualities have to be taken care of unlike
at educational institutions, where the sole aim is to learn. What may seem to be software
complete in all respects may end up throwing a user into disarray because of very minor
flaws.we were required to meet the stringent demands of clients and that too with the
stipulated deadline. Though this seemed tough at first. we realized that pressure goaded
us on to develop better and better application. This section provides me an opportunity to
do self-introspection of what value we have added to our knowledge and skill set and to
the project.
During the project the real importance for following all the principles of system analysis
and design dawned on me. we felt the necessity of going through the several stages
because only such a process could makes one understand the problem at hand, more so
due stores involved in their manipulation.
6.2 Proposal/scope of future enhancement
Completion of the development process will result in a software package that will
provide user-friendly environment, which is very easy to work with, even for people with
very little knowledge of computer. Management of various tasks is incorporated in the
package and will deliver the required information in a very easy to use and easy to access
manner. This package will provide accuracy, efficiency, speed and easiness to the end
user. Since the system is verified with valid as well as invalid data and is run with an
insight into the necessary modifications that may require in the future, it can be
maintained successfully without much hassles.
