1. PROBLEM STATEMENT:

The online voting system is the system implemented to make the voting system easy for both

polling and also for the administrator to view and check the result for each area individually.

Here the voting is done anywhere with in spite of the area in which they reside.

The voters or the administrator can login only if they already have a user id and password.

New user can be only created by the administrator.

The voter can login with his user id only if he has not casted the vote already. If he has already

casted the vote the voter status is changed to voted and he cannot login with that user id unless

the administrator refreshes the voting system.

The administrator controls all parts of the online voting system except the vote casting part

which is restricted to the voters only. The administrator is the only one who can create new

voter.

The administrator is the soul controller of the online voting system. He can create new

nominees for the election and he can view the individual election status for each locality. The

graphs are enabled to show the election status easily.

The voter when logs in he can view his personal details which cannot be edited by him he can

only report the changes to the administrator who can edit the details. The voter is granted

permission only to view his personal details and vote.

The voter while voting is provided with two options, one he can vote to any one of the

nominees in the ballot page and another he can register his vote as not willing to vote to avoid

the illegal voting.

The flow of the administrator and the voter completely differs based on the authentication type

which they choose.

2.INTRODUCTION:

2.1.Introduction about online voting system:

The online voting system is the system that aims in reducing the complexity and cost of the

election process. Here the voter can vote in spite of his absence in the particular locality. The

administrator’s effort is much reduced by checking the election status of all the localities

individually forms a place and it is easy for him to announce the election result. The

administrator is the soul controller of the online voting system in all process including refreshing

the votes, editing the voter details, creating new nominee and so on. Thus the online voting

system can reduce the cost and effort of election process.

In this voting system each voter will be provided with a specific voter-id and a password

through which access for the voting can be granted. If once the access is granted for a voter-id

then the access is denied for logging in till the voting system is refreshed for the next election.

Similarly the administrator will be provided with a special id through which he can view the

status of the election.

Based on the id segregation between the voter and administrator is carried out initially. If the

user id is invalid then an error message will be displayed. If the id entered is of type

administrator then an information i.e., the election status will be displayed which changes

dynamically. Otherwise the voter information will be displayed which changes dynamically

depending on the changes made which will proceed him to the next level in which he can cast his

vote and it is updated automatically.

The advantages of the online voting system is that the speed of information retrieval and

updating is made easy and other advantage are

High level security to avoid illegal polling.

Online implementation makes it easy for voters to participate in election.

As for considering election commission board it becomes easier to conduct election.

Election expenses can be reduced.

Non-Residential citizens can also participate in the election.

2.2.Rational Rose:

The Rational Environment was organized around a persistent intermediate representation

(DIANA), providing users with syntactic and semantic completion, incremental compilation, and

integrated configuration management and version control. To overcome a conflict between

strong typing and iterative development that produced recompilation times proportional to

system size rather than size-of-change, the Rational Environment supported the definition of

subsystems with explicit architectural imports and exports; this mechanism later proved useful in

protecting application architectures from inadvertent degradation. The Environment's Command

Window mechanism made it easy to directly invoke Ada functions and procedures, which

encouraged developer-driven unit testing.

The Rational Environment ran on custom hardware, the Rational R1000, which implemented a

high-level architecture optimized for execution of Ada programs in general and the Rational

Environment in particular. The horizontally-microprogrammed R1000 provided two independent

64-bit data paths, permitting simultaneous computation and type checking. Memory was

organized as a single-level store; a 64-bit virtual address presented to the memory system either

immediately returned data, or triggered a page fault handled by the processor's microcode.

Rational provided code generators and the cross-debuggers for then-popular instruction set

architectures such as the VAX, Motorola 68000, and x86; much of this was accomplished

through a partnership with Tartan Labs, founded by Bill Wulf to commercialize his work on

optimizing code generators semi-automatically produced from architecture descriptions (PQCC).

2.3.VISUAL BASIC:

Visual Basic (VB) is the third-generation event-driven programming language and integrated

development environment (IDE) from Microsoft for its COM programming model. VB is also

considered a relatively easy to learn and use programming language, because of its graphical

development features and BASIC heritage.

Visual Basic was derived from BASIC and enables the rapid application development (RAD)

of graphical user interface (GUI) applications, access to databases using Data Access Objects,

Remote Data Objects, or ActiveX Data Objects, and creation of ActiveX controls and objects.

Scripting languages such as VBA and VBScript are syntactically similar to Visual Basic, but

perform differently.

A programmer can put together an application using the components provided with Visual

Basic itself. Programs written in Visual Basic can also use the Windows API, but doing so

requires external function declarations.

The final release was version 6 in 1998. Microsoft's extended support ended in March 2008

and the designated successor was Visual Basic .NET (now known simply as Visual Basic).

Microsoft has developed derivatives of Visual Basic for use in scripting. Visual Basic itself is

derived heavily from BASIC, and subsequently has been replaced with a .NET platform

version.Some of the derived languages are:

Visual Basic for Applications (VBA) is included in many Microsoft applications

(Microsoft Office), and also in many third-party products like SolidWorks, AutoCAD,

WordPerfect Office 2002, ArcGIS, Sage Accpac ERP, and Business Objects Desktop

Intelligence. There are small inconsistencies in the way VBA is implemented in different

applications, but it is largely the same language as VB6 and uses the same runtime

library.

VBScript should not be confused with ASP.NET which uses the .NET Framework.

7

Visual Basic .NET is Microsoft's designated successor to Visual Basic 6.0, and is part of

Microsoft's .NET platform. Visual Basic.Net compiles and runs using the .NET

Framework. It is not backwards compatible with VB6. An automated conversion tool

exists, but fully automated conversion for most projects is impossible.[14]

StarOffice Basic is a Visual Basic compatible interpreter included in StarOffice suite,

developed by Sun Microsystems.

Gambas is a Visual Basic inspired free software programming language. It is not a clone

of Visual Basic, but it does have the ability to convert Visual Basic programs to Gambas.

VBScript is the default language for Active Server Pages. It can be used in Windows scripting

and client-side web page scripting. Although it resembles VB in syntax, it is a separate language

and it is executed by vbscript.dll as opposed to the VB runtime. ASP All versions of the Visual

Basic development environment from 1.0 to 6.0 have been retired and are now unsupported by

Microsoft. The associated runtime environments are unsupported too, with the exception of the

Visual Basic 6 core runtime environment, which will be officially supported by Microsoft for the

lifetime of Windows 7. Third party components that shipped with Visual Studio 6.0 are not

included in this support statement. Some legacy Visual Basic components may still work on

newer platforms, despite being unsupported by Microsoft and other vendors.Development and

maintenance development for Visual Basic 6 is possible on legacy Windows XP, Windows Vista

and Windows 2003 using Visual Studio 6.0 platforms, but is unsupported. Documentation for

Visual Basic 6.0, its application programming interface and tools is best covered in the last

MSDN release before Visual Studio.NET 2002. Later releases of MSDN focused on .NET

development and had significant parts of the Visual Basic 6.0 programming documentation

removed. The Visual Basic IDE can be installed and used on Windows Vista, where it exhibits

some minor incompatibilities which do not hinder normal software development and

maintenance. As of August 2008, both Visual Studio 6.0 and the MSDN documentation

mentioned above are available for download by MSDN subscribers.

3. PLANNING:

3.1. MS-Office Project 2010:

The tool that we are using for planning is the MS-Office Project 2010. Using this tool we are

going to track our project development progress. The tool is very easy to use so that we can able

to easily pictorically denote our project’s progress. In our project we are going to plan for the

modules like login, area selection, ballot sheet and status viewing.

Create and maintain an optimized project execution plan

Forecast and manage detailed project costs and track variances against the budget

Track and analyze project progress according to the project plan

Communicate and report project plans and progress effectively with useful reports

and graphical representations of project information

Plus, Project 2010 can be used with existing Project files and previous versions of Microsoft

Office applications, so you can start enjoying the benefits right away.

Project Professional 2010 also provides collaborative enterprise project management

capabilities when used with Microsoft Office Project Server 2010.

Project 2010 enables users to better:

Create and Maintain Plans:

Schedule projects to get productive quickly and ensure that projects are delivered on time

and within a budget.

Set up projects quickly to lower project cycle time and improve efficiency.

The Project Guide, a step-by-step interactive guide, has been improved to quickly and easily

enable users to set up projects, manage tasks, resources, and task status, and report project

information. This feature helps start projects faster and manage project elements effectively.

Save time with templates and promote consistency throughout the project to increase

overall effectiveness.

11

A rich set of out-of-the-box templates in Project 2010 helps accelerate the project creation

process. A Project template pre-populates task and resource information, and applies formatting,

macros, and other project-specific settings.

Forecast and Manage Costs:

Monitor project financials to forecast and manage project costs and track variances

against the budget.

Assign costs to project tasks, providing a clearer picture of the project’s total cost

The new Cost Resources feature enables users to assign costs to tasks and provides new fields for

cost information that enable better project accounting, resulting in precise project cost estimates.

This feature also supports integration of Project 2010 with many popular accounting systems.

Track and Analyze Progress:

Track and analyze project progress effectively according to the project plan to get clear

visibility into project risks and issues, and to gain better project insight.

4. COST ESTIMATION

4.1. COCOMO II

The cost plays a major role in developing the projects. So we have to calculate the cost

estimates of our projects in a effective way so as to have a very good project development. In our

project the cost estimation depends upon the staff and the days they are going to work on the

particular module so that the working costs can be borne by the organization by funding the

staffs.

COCOMO II Effort Equation:

The COCOMO II model makes its estimates of required effort (measured in Person-

Months – PM) based primarily on your estimate of the software project's size (as measured in

thousands of SLOC, KSLOC)):

Effort = 2.94 * EAF * (KSLOC)E

Where

EAF Is the Effort Adjustment Factor derived from the Cost Drivers

E Is an exponent derived from the five Scale Drivers

As an example, a project with all Nominal Cost Drivers and Scale Drivers would have an EAF of

1.00 and exponent, E, of 1.0997. Assuming that the project is projected to consist of 8,000 source

lines of code, COCOMO II estimates that 28.9 Person-Months of effort is required to complete

it:

Effort = 2.94 * (1.0) * (8)1.0997 = 28.9 Person-Months

COCOMO II Schedule Equation:

The COCOMO II schedule equation predicts the number of months required to complete

your software project. The duration of a project is based on the effort predicted by the effort

equation:

Duration = 3.67 * (Effort)SE

17

Where

Effort Is the effort from the COCOMO II effort equation

SE Is the schedule equation exponent derived from the five Scale Drivers

Continuing the example, and substituting the exponent of 0.3179 that is calculated from the scale

drivers, yields an estimate of just over a year, and an average staffing of between 3 and 4 people:

Duration = 3.67 * (42.3)0.3179 = 12.1 months

Average staffing = (42.3 Person-Months) / (12.1 Months) = 3.5 people

In our project we are going to estimate the cost for 12 module like login, view personal

details, select the voting area, ballot sheet, administrator menu, view status, New nominee,

change authentication, change voter details, new voter, select status area, voter

authentication.

5. ANALYSIS PHASE

The Analysis is done with the help of Rational Requisite Pro. The three views or reports

which form the basis for analysis are

1. Attribute Matrix

2. Traceability Matrix

3. Traceability Tree

5.1 ATTRIBUTE MATRIX

The Attribute Matrix view is a spreadsheet like display that lists the requirements of a specific

requirements type and their attributes. Requirements are arranged in rows, listed by tag number

and followed by requirement name. Attributes are arranged in columns.

Figure 5.1 - Attribute matrix for the online voting system

25

5.2 TRACEABILITY MATRIX

Traceability Matrix is a view that illustrated the relationships between requirements of the

same or different types. We can use this matrix to create, modify and delete traceability

relationships and view indirect relationships and view direct relationships and traceability

relationships with a suspect state. We can also use the traceability matrix to filter and sort the

requirements and columns requirements separately.

Figure 5.2 - The traceability matrix for the online voting system

27

5.3 TRACEABILITY TREE

A view that displays all internal and external requirements traced to or from a requirement.

The traceability tree only displays the first level project traceability.

6. SOTWARE DESIGN:

6.1. USE CASE MODEL

The Use Case Model describes the proposed functionality of the new system. A Use Case

represents a discrete unit of interaction between a user (human or machine) and the system. A

Use Case is a single unit of meaningful work; for example login to system, register with system

and create order are all Use Cases. Each Use Case has a description which describes the

functionality that will be built in the proposed system. A Use Case may 'include' another Use

Case's functionality or 'extend' another Use Case with its own behavior.

Use Cases are typically related to 'actors'. An actor is a human or machine entity that

interacts with the system to perform meaningful work.

6.1.2.USECASE SPECIFICATION:

LOGIN

Brief Description

 The use case describes how Voter and administrator logs into the online voting system.

Flow of Events

Basic Flow

 This use case starts when the Voter and administrator wishes to Login to the Online voting

system.

1. The System requests that the Voter and administrator to enter his/her voter-id, user-id,

authentication type and password.

2.  The voter and administrator’s user-id, voter-id and password.

3. The System validates the entered user-id, voter-id, authentication type and password and

logs the user into the System

Alternative Flows

Invalid Name/Password

If, in the Basic flow, the user enters an invalid user-id, voter-id, atuthentication and/or

password, the system displays an error message. The user chooses to either return to the

beginning of the Basic flow or cancel the login, at which point the use case ends.

Special Requirement

 None

Pre-Conditions

None

Post-Conditions

 If the use case was successful, the user is now logged into the system based on the

authentication type. If not, the System State is unchanged.

37

SELECT AREA

 Brief Description

 The administrator and the voter have to select the area in which either the voting has to be done

or the locality where the voting status has to be viewed.

 Basic flow

 1. The user must provide the system with the state, district and locality.

2. The user has to lock each and every selection so that the locality cannot be altered.

 Alternate flow

 If the voter or the administrator doesn’t select the locality completely then they will neither be

allowed the cast the vote nor can view the election status in progress.

 Special Requirements

 None

  Pre-Conditions

 The user has to first login by giving the type of authentication which allows them to select area.

 Post-Conditions

 If the use case was successful, the voter will reach the ballot sheet where he can cast the vote

and the administrator will reach the election status page to view the election status of the

particular locality.

 

39

BALLOT SHEET

 Brief Description

 This use case is enables the voter to cast the vote and register him as valid voter and his status as

voted.

 Basic flow

 1. The voter moves on to the ballot sheet by providing the following details

a) State

b) District

c) Locality

2. If the voter does not select any nominee to cast his vote then his decision is first confirmed by

the system and then his vote is registered as not willing to vote to anyone. Else the vote is

registered to the selected nominee.

 Alternative flow

If the voter doesn’t wish to vote for any one then he/she should not select any candidate in the

ballot sheet then must click cast vote and log out to register as not willing to vote to any one.

 Special Requirements

 None

 Pre-Conditions

 The voter has to initially provide the online voting system with the state, district and locality.

 Post-Conditions

 If the casting of vote is successful then the voter-id is registered to voted status such that he

cannot login again.

 Extension Points

 None

41

ELECTION STATUS

Brief Description

 This use case helps the administrator to view the election status for each locality uniquely with

graph to enable easy view of status

Basic flow

 This use case used by the administrator to view the election status of the election which is

already in progress which is displayed based on the locality which the administrator selects.

Alternate flow

 If the election viewing area is not selected then the election status cannot be viewed by the

administrator unless he provides the full details about the area.

Special Requirements

 None

Pre-Conditions

 The administrator can view the status only if the election viewing locality is already being given

to the system as input.

Post-Conditions

 If the administrator views the election status then the he can only return to main menu.

 Extension Points

 None
