1 INTRODUCTION TO ELECTRICITY BILL MANAGEMENT
SYSTEM (EBMS)
1.1 Introduction to Our project entitled “Electricity Bill Management
System”(EBMS) aims is to generate electricity bill with all the charges. Manual
system that is employed is extremely laborious and quite inadequate. It only
makes the process more difficult and hard.
The aim of our project is to develop a system that is meant to partially
computerize the work performed in the Electricity Board like generating
monthly electricity bill, record of consuming unit of energy, store record of the
customer.
We used Microsoft Visual Basic 6.0 as front end and MS-Access 2000 as back
end for developing our project. Visual Basic is primarily a visual design
environment. We can create a VB application by designing the form and that
make up the user interface. Adding visual basic application code to the form
2

and the objects such as buttons and text boxes on them and adding any required
support code in additional modular.
Microsoft Access 2000 is a powerful relational database application with which
a desktop user can efficiently create and manipulate database systems. Access
targets the desktop category and works best for individuals and workgroup.
Managing megabytes of data for multi-user access to the same database, Access
uses file-server architecture, rather than client-server architecture.
Access is included in the professional and developer editions of Microsoft
office.
The overall project report is divided into some parts. These parts are further
divided into their subparts. In the parts we have described the purpose, scope of
the project, objective of the project i.e. approach which used for developing this
software. It includes the topics like the problems with the existing system and
the functionality of the organization. Introduction to tools, design, coding,
testing and debugging of the system are discussed in very detail. We have also
provided the names of the books from which we have taken guidance to
complete the work. Last section contains the matter about the overall work
performed and the efforts taken to complete the project.
1.2 Scope:
Our project aims at Business process automation, i.e. we have tried to
computerize various processes of Electricity Bill Management System. In the
sector of electricity board we have computerizes their department and stock
maintenance.
Scope of any software depends upon the following things:
3

1. It satisfy the user requirement
2. Be easy to understand by the user and operator
3. Be easy to operate
4. Have a good user interface
5. Be expandable
6. Delivered on schedule within the budget.
We have tried to make such type of software, which satisfy the above given
requirement.
1.3 OBJECTIVES OF THE EBMS:
The firm handles all of the work manually, which is very tedious and
mismanaged.
The objective of our project is as follows:
a. To keep the information of Customer.
b. To keep the information of consuming unit of energy of current month.
c. To keep the information of consuming unit of energy of previous month.
d. To keep the information of employee working in the department.
e. To maintain the record of the department.
f. Information retrieval will become easy.
g. Security measure will be adopted, by maintaining the login of username and
the password.
h. Data redundancy will be greatly reduced because this new system is built
using Visual Basic 6.0 as front-end. It entails looking into duplication of efforts
bottlenecks and inefficient existing procedures

Software Environment
The application front end will be designed using Visual Basic 6.0.
1. Microsoft Visual Basic 6.0
2. Microsoft -Access 98 or higher version.
3. Windows 98 or higher version.
4. One Printer for printing the electricity bill.
2.1 FRONT END
MICROSOFT VISUAL BASIC 6.0
Visual Basic 6.0 is an enjoyable language due to its visual environment.
Building a windows program in Visual Basic requires dragging and dropping
graphic objects on to the screen from a toolbox. Thus Visual Basic is the
efficient GUI tools to develop some exciting windows-based application.
Visual Basic 6.0 is much more than just a programming language. The
programming language forms the background of all that takes place in a
running Visual Basic program. The language is a secondary consideration to the
user interface. A windows program offers a high degree of user interaction
using the graphical elements that forms the objects on the window the user
sees .If the user interface is not correct, user will not like the program.
6

Visual Basic lets one add menus, text boxes, command buttons, option buttons
(for making exclusive choice), check boxes, list boxes, scroll bars and file and
directory boxes to black windows. One can use Visual Basic to communicate
with other applications, running under windows. Visual Basic offers: More
Internet features, better support for data base development, more language feature
to make programming job easier.
Over past few years visual basic 6.0 (front end) the relational data base
management system has been fine-tuning it is offering a large complex
application in the relational market. Visual basic 6.0 is a front end (i.e. uses
graphical user interface) visual basic 6.0 uses windows environment. It may use
any DBMS or RDBMS as a back-end through ODBC (open database
connectivity).
For our purpose of development, in our project we used Visual Basic 6.0
because visual basic 6.0 has following outstanding features and qualities.
Advantages Of Visual Basic:
1. Visual Basic applications are event driven. Event driven means the user is in
Control of the application.
2. Visual Basic supports the principle of object-oriented design.
3. Visual Basic is a complete window application development system.
4. Visual Basic is infinitely extensible through the use of active x controls
dynamically linked libraries (dll's) and adds dins.
The Fast Track To Windows Development
7

Visual Basic is primarily a visual design environment. We can create a VB
application by designing the form and that make up the user interface. Adding
visual basic application code to the form and the objects such as buttons and
text boxes on them and adding any required support code in additional modular.
Friendly Environment
Creating a form, adding controls to form and writing code behind the form are
all managed within a friendly environment.
Graphical User Interface
Application developed in DOS environment has to include its own set of video,
keyboard and printer drivers. in other words many DOS programs provided
virtually no user interface at all. Since windows is preferable over DOS and
Visual Basic is windows based hence millions of users can use applications
with no documentation or training:
The graphical user interface provides a graphical environment to user as front-
end for their operating system through graphical objects and therefore screen
looks very attractive and almost has three-dimensional qualities. The point and
shoot use of a GUI (Graphical User Interface) make use of the operating system
and programming easy.
Visual basic 6.0 connect to number of back-end DBMS and RDBMS such as
SQL, FoxPro, Sybase, Oracle etc.
8

Open Database Connectivity
Visual basic 6.0 connects to any back-end DBMS system whose DBMS cores
follow the open database connectivity rules and this connectivity is established
by open database connectivity.
The data storage may belong to any DBMS engine specifically supported by
visual basic 6.0 driver or any DBMS that supported open database connectivity.
The data entry and validation screens are created in visual basic 6.0 connects
with whichever engine is specified at the time of screen was created and
manipulated data within that engine.
SOME TOOLS OF VISUAL BASIC 6.0
 Data access features allow creating databases, front-end applications and
scalable server side components for most popular databases formats including
Microsoft SQL server and other enterprise level databases.
 Active technology allows using functionality provided by other applications
such as Microsoft Word, Microsoft Excel and other applications and objects
could be created using the Professional Enterprise editions of Visual Basic.
 Internet capabilities make it easy to provide access to documents and
applications across the Internet or Intranet server applications.
The finished applications are a true .exe files that uses a Visual Basic virtual
machine that can be freely distributed.
2.2 BACK END

Introduction of MS-Access
Over the past several years, relational database management system have
become the most widely accepted way to manage data relational system often
benefits such as:
1. Easy access to all data.
2. Flexibility in storage and modeling.
3. Reduced data storage and redundancy.
4. Independence of physical storage & logical data designs.
5. A high-level data manipulation language (SQL).
6. Tables & table operations are well defined because relational theory is
founded in set theory, relational algebra & relational calculus.
Out of this the reason for introducing relational model is to increase the
productivity of the application programmer by eliminating the need to change
application programs when a change is made to the database.
As the technologies associated with RDBMS have grown rapidly in recent
years, the appeal of relational databases has become apparent to a much wider
audience.
The phenomenal growth of the relational technology has led to more demand
for RDBMS in environments ranging from personal computer to large highly
secure CPU with users ranging from very casual to very sophisticated.
Microsoft Access 2000 is a powerful relational database application with which
a desktop user can efficiently create and manipulate database systems. Access
targets the desktop category and works best for individuals and workgroup
Managing megabytes of data for multi-user access to the same database. Access
uses File-server architecture, rather than client-server architecture.
10

Access is included in the professional and developer editions of Microsoft
office.
The only problem with MS-ACCESS is that it cannot provide strong security
features. But in front of its fast execution features this drawback can be
neglected as the firm does not need any type of security whether it is
operational, database, or any other security. But in application development
some restriction are made of some places so that our database cannot be
corrupted.
MS-ACCESS is therefore used for its fast execution speed and also due to
its fast connectivity.
Importance of database:
Growth in the usage of Computers in Business and Industrial sector initiated
development of modern Database Software. Database software’s offers a
number of potential advantages over traditional file-processing system; some of
them are as follows:
• Program-Data Independence
The separation of data descriptions (metadata) from the application programs
that use the data is called data-independence. With the database approach, data
descriptions are stored in a central location called repository. This property of
the database systems allows an organization’s data to change and evolve
without changing the application programs that process that data.
• Minimal Data-Redundancy
11

The design goal with database approach is that previously separate and
redundant data files are integrated into a single, logical structure. Each primary
fact is recorded in only one place in the database. The database approach does
not eliminate redundancy entirely, but it allows the designers to carefully
control the type and amount of redundancy.
• Data Consistency
By controlling data redundancy, we greatly reduce the opportunities for
inconsistency. In database approach updating data values is greatly simplified
when each value is stored in one place only. Finally we avoid the wasted
storage space that results from redundant data storage.
• Data Sharing
Primary advantage of database approach is sharing of data. A database is
designed as a shared resource. Authorized users are granted permission to use
the database and each user is provided one or more user views to facilitate this
use. A user view is a logical description of some portion of database that is
required by the user to perform some task.
• Enforcement of Standards
When the database approach is implemented with full management support, the
database administration function should be granted single point authority and
responsibility of establishing and enforcing data standards. These standards will
include naming conventions, data quality standards and uniform procedures for
12

accessing, updating and processing data. The data repository provides database
administrators with powerful tools for developing and enforcing such standards.
• Reduced Program Maintenance
Stored data must be changed frequently for a variety of reasons: new data item
types are added; data formats ate changed and so on. In file processing
environment, the description of data formats and access methods inevitably
result in the need to modify application programs. As a result in the change of
data formats and access methods inevitably results in the need to modify
application programs. In a database environment, data are more independent of
application programs that use them. Within limits, we can change either the
data or the application programs that use the data without necessitating the
change in other factors.
Database: -A database is a set of data, organized for easy access. The database is
the actual data. It is the database that you will be accessing when you need to
retrieve data.
Data Dictionary: -The data dictionary is a set of tables Access uses to maintain
information about the database. The data dictionary contains information about
tables, indexes, clusters, and so on.
DBA (Database Administrator): -The DBA is the person responsible for the
operation, configuration, and performance of the database. The DBA is charged
with keeping the database operating smoothly, ensuring that backups are done on a
regular basis (and that the backups work), and installing new software. Other
13

responsibilities might include planning for future expansion and disk space needs,
creating databases and tablespaces, adding users and maintaining security, and
monitoring the database and retuning it as necessary. Large installations might
have teams of DBAs to keep the system running smoothly; alternatively, the tasks
might be segmented among the DBAs.
DBMS or RDBMS: -The Database Management System is the software and
collection of tools that manages the database. Access software is the DBMS. A
Relational Database Management System is a DBMS that is relational in nature.
This means that the internal workings access data in a relational manner. Access is
an RDBMS.
Query: -A query is a read-only transaction against a database. A query is generated
using the SELECT statement. Users generally distinguish between queries and
other transaction types because a query does not change the data in the database.
Schema: -A schema is a collection of objects associated with the database.
Microsoft Access is a very effective DBMS tool which is generally used by all the
users. It is compatible with all types of systems & can be installed and used as and
when required.
2.3 VB CONTROLS
FEATURES OF VISUAL BASIC 6.0
14

Toolbox: The Tool Box window differs from the tool bar. The Tool Box is a
collection of tool that acts as a repository of controls we can place on forms. Some
tools are Selection Pointer, Picture Box, Label, Text Box, Frame Button, Command
Botany, Check Box, Option Button etc.
Form: Visual Basic uses a window; controls are the widgets one place of a form. In
a form we will customize by adding controls such as command buttons, list boxes to
it. At the top of the black form is the little bar with its caption.
Common Form properties:
There are several common properties to customize a form, these are: -
Caption: Caption is used as a title that the Microsoft Window for the application
icon when the user minimizes the application.
Name: This property is used to give the name that one want to use to refer to the
form.
Enabled: If user sets Enabled to false, the form cannot respond to any events such
as the user checking on the form.
Icon: The icon property determines the icon users application will display when it is
minimized on tool bar or turned into a stand-alone application on windows desktop.
Visible: If the value of the property is set to false, it will no longer be visible.
Text Boxes: It is used to display text or to accept user input. Most of the code is
written to process the information users enter into them. Several properties of text
boxes are as follows: -
15

Text: The text property in text box is the analog of the caption property for a
command button or a form; it controls text the users see. It determines whether text
on the control such as label or command button, is left justified, centered, or right
justified on the control. The Alignment property take one of the three values: 0-Left
justify, 1-Right justify, 2-Center.
Multiline: This property determines whether a text box can accept more than one
line of text when the user runs the application, and it is usually combine with
resulting the value of the scrollbar property. If true the property specifies the text
box can hold more than a line of text.
Max Length: This property specifies the maximum number of characters that the
text box will accept. A value of 0 indicates that the user can enter a value of any
length.
Locked: This property determines whether the user can enter a value or change the
default value of the text box. If true, the user cannot change the text box value until
the program, at run time assigns a false to this property.
Password char: The Password property lets us limit what the text box displays.
Labels: Use Labels to display information programmer does not want the user to be
able to change. Most common use for Labels is to identify a text box or other control
by describing its contents. Another common use is to display help information.
Message Boxes: It display information in the dialog box superimposed on the form.
They want for the user to choose a button before return to the application. User
16

cannot switch to another form in programmers applications as long as Visual Basic
is displaying a message box.
Option Buttons: They all work together. When the user chooses one button, all
other buttons in the group are turned off. The value property of the option button
tells us whether a button was selected by the user. If the value property is true, the
user selected that button; otherwise, its value property is false.
Check Boxes: It differ from option button in that, regardless of how many Check
Boxes one places on a form, they can all be turned on and off independently. If the
user has selected Check Boxes, the value property switches to true. It stays true until
the user deselects that box.
List and Combo boxes: Use list boxes when we have a fixed list of choices. Visual
Basic automatically adds vertical scroll bars when the list box is small for all items it
contains.
To allow users to input data as well as choices from a list, we use a Combo Box.
FOLLOWING ARE THE CUSTOM CONTROLS, WHICH ARE ALSO
DATA AWARE:
 Data List
 Data Combo
 Data Grid
 Microsoft Flex Grid
17

 Microsoft Hierarchical Flex Grid
 Rich Textbox
 Microsoft Chart
 Image Combo

5 SYSTEM DEVELOPMENT ENVIRONMENT:
System development environment shows the hardware and software
requirement, which is necessary for developing the software. Necessary
software and hardware requirement, which are necessary for making this
software are as follows
5.1 Client server computing and visual basic 6.0:
The client / server programming is also a distributed application processing and
co-operating application processing. It has three distinct components, each
focusing on specific job.
The three components are:
1. Client application
2. A Database Server
3. A network for connecting the first two components.
1. Client Application:
Client application (i.e. front end) is the part of the system that users employ to
interact with data. The work of client is requesting and receiving information
forms a database server (back-end). Client application can be developed rapidly
using visual basic 6.0.
2. A Database Server:
A Database server focuses on efficiently managing resources such as the table
in which data lies. The server’s primary job is to manage the data tables
54

optimally among multiple clients that concurrently request server for same
resources. Visual basic can connect to a number of RDBMS that are in trend.
3. Network for connecting the first two components:
A network and communication software are the vehicle that transports the data
between the clients and the server. The system both client and server run
communication software that allow them to talk across a network.
Visual Basic Libraries:
When we create commercial application we create object such as windows, data
windows, menus etc. these objects that you create using an appropriate visual
basic pointer are stored in libraries files.
When application has to run visual basic there objects from their libraries and
visual basic gives you a library painter to help you manage your libraries.
Events in Visual Basic:
Visual basic commercial applications are event driven. The user of the
application
Controls the flow of the application by the action they take.
5.2 Features of Visual Basic:
1. Visual basic provides a GUI which and therefore screen looks very attractive.
2. Work on client / server computing model.
3. Object Oriented programming approach.
4. Visual basic provides several tool bars, which make working quick and easy.
5. It is front end and DBMS as a back end so it uses all the features of RDBMS
like referential integrity foreign key etc.
55

Feel Of Windows Environment
Microsoft Windows environment is built-in to Visual Basic application. No
need to work with any windows compatible hardware since windows provides
drivers for thousand of different printer’s video adapter, modems and other
peripherals.
5.3 PRELIMINARY DESIGN OF PROPOSED SYSTEM:
Data Design:
In most situations, many physical database design decisions are implicit or
eliminated when we choose the database management technologies to use with
the information system we are designing. Since many organizations have
standard for operating systems, database management system and data access
languages, we must deal only with those choices not implicit in the given
technologies.
The primary goal of database design is data processing efficiency.
Objective Of Database Design:
i) To decide on the organization of the database in computer storage and
define the physical structure of the database management system.
ii) To outline the program to process transactions and to generate
anticipated management information and decision support reports.
Designing Fields: A field is the smallest unit of application data recognized
by system software
Choosing Data Types: A data type is a detailed coding schema recognized
by the system software, such as a DBMS, for representing organizational data.
56

6 TESTING AND DEBUGGING:
Software testing is a critical element of software quality assurance and represents the
ultimate reviews of specification, design and coding. Testing presents an interesting
anomaly of the software. During earlier definition and development phases, it was
attempted to build software from abstract concept to a tangible implementation.
The testing phase involves the testing of the developed system using various set
data. Presentation of test data plays a vital role in system testing. After preparing the
test data the system under study was tested using test data. While testing the system
by using test data errors were found and corrected. A series of tests were performed
for the proposed system before the system was ready for implementation
6.1 The various types of testing done on the system are:
 Unit Testing
 Integration Testing
 Validation Testing
 User Acceptance Testing
 System Testing
Unit Testing:
Each module is considered independently. it focuses on each unit of software as
implemented in the source code. it is white box testing.
Integration Testing:
Integration testing aims at constructing the program structure while at the same
constructing tests to uncover errors associated with interfacing the modules.
modules are integrated by using the top down approach.
57

Validation Testing:
Validation testing was performed to ensure that all the functional and
performance requirements are met.
System Testing:
It is executing programs to check logical changes made in it with intention of
finding errors. a system is tested for online response, volume of transaction,
recovery from failure etc. System testing is done to ensure that the system
satisfies all the user requirements.
User Acceptance Testing:-
User acceptance of a system is the key factor for the success of any system. The
system under consideration was tested for users acceptance by constantly
keeping in touch with the perspective system user at the time of developing and
making changes wherever required. This is done with the regards to the
following points:
The success of system depends on how accurately a problem is defined,
thoroughly investigated carried out through choice of solution. User need
identification and analysis that are concerned with what the uses needs rather
than what he/she wants. System explains how to perform specific activities or
task, which does what and what.
SCOPE AND RESULT DISCUSSION
Even the best system developed has some flaws or others. There always exist
scope of further improvement in the system. The effect of implementations of
new computerized system is found remarkable.
58

The following are the major improvement of the new system over the existing
system.
 A fully menu driven user-friendly computerized system has been developed
where the user can perform task like entering data, deleting and updating the
information All the operations are carried automatically preventing a lot of
manual work.
 Additional checks have also been incorporated into the system to avoid
duplications of data as far as possible.
6.2 SCOPE FOR FURTHER IMPROVEMENT
Every project whether large or small has some limitations no matter however
diligently developed. In some cases limitations is small while in other cases they
may be broad also. The new system has got some limitations. Major areas where
modifications can be done are as follows:
 Our system is not online so further it can be improved.
 The security is limited so some additional arrangement could be made to
provide more security to the system.
 This system is calculates bill upon the totaled unit consume, not on the
previous reading or current reading.
 There is no provision of complain handling so further it can be added.
59

 This software does not contain any fixed charge/penalty for late bill
paid/advanced bill paid in bill calculation.
6.3 MAIN ACHIEVEMENT OF THE SYSTEM
This project gives an overview of the Electricity Bill Management System.
After entering into the project, user is left with several options via –
a) The user can take new connections.
b) The user can view the existing lists of customers, which already have
telephone connections.
c) It calculate bill upon the different units.
d) The user can of course see bills & take billing statements.
e) The user can also do several administrative works like managing rates of
calls, addition or modification of metered calls & customer entries.
It is a computerized system, which can be used very easily & effectively by the
administrators of the Electricity Bill Management System.
60

CONCLUSION
We have tried to develop a system that can be a great help for the owner of the
referred electricity department to receiving bill from the customer. Despite all
our efforts there are some bugs in the system, which are still to be removed.
This is possible by the testing being done in the system.
We have left all the options open so that if there is any other future requirement
in the system by the user for the enhancement of the system then it is possible
to implement them.
In the last we would like to thanks all the persons involved in the development
of the system directly or indirectly. We are also thankful to the Rajendra Nagar
South Division Electricity Department of NDPL for so much taken by them in
helping to develop the system.
We hope that the project will serve its purpose for which it is develop there by
underlining success of process.
