Acknowledgement

This project is being the Ist live project made by me in the duration of this course (PGDCA) is an unforgettable experience. I would like to thank all of them who were associated with me in making this project a success.

I would like to thank Mr. R. K. Sharma and Ms. Sonia Sodhi of SGSS-IIT, Jangpura Ext., New Delhi, who helped me in completion of this project. They had to answer all queries and an unconditional support that provided me without which it would have been impossible to do this project

I heartily thank my faculty Ms.Sharanjeet Kaur and Preeti Marwah who gave me the hope and inspiration to go ahead with this project. I would like to thank my friends for their innovative ideas & views and for that timely assistance which they provided during the course of this project.

I would also like to thank my parents for their blessing and assistance they provided to me during the course of this project; And last but not the least I would like to thank almighty god for what ever he provided me and made this project a success.

About Project

The Gas Agencies and the number of gas users are seems to

increasing day by day. The transactions like booking gas, releasing

gas, keeping records of all customers, stock maintaining etc. when

being processed manually take up a lot of time and thus add to the

problems of the management. And thus to keep track of the

transactions of the gas agency, a software package seems to be best

way as it will speed up the work time and lessen up the

complexities of the management. In simple language the project

provides such user friendliness and easy understandability that

even a novice user will find it easy to use the package and grasp its

essence.

Objective

Objective of this software is to computerize the manual system of a

Gas Agency, so that all the transactions become fast and easy. It

replaces all the paper work. It works according to the need and

lowers the work load of user.

Data Structure

Five tables have been used in this project to store data:

1. tblConsumer : Keeps record of consumer.

ConsumerNo : Unique code allotted to every consumer.

Name : Name of the consumer.

Address : Address of the consumer.

Pin : Pin code of the location.

Phone : Phone no. of the consumer.

DoC : Date of connection.

Cylinders : No. of cylinders consumer have.

CylinderType : Type of cylinder – Domestic/Commercial

2. tblConsumerTrans : Keeps record of gas booking and release.

Slno : Serial no.

ConsumerNo : Unique code allotted to every consumer.

DateofBooking : Date of gas booking.

DateofRelease : Date of releasing the gas to consumer.

IsReleased : Flag variable containing value yes or no.

Remarks : Any remarks for the booking.

3. tblPrice : Keeps record of cylinder price.

CylinderType : Type of cylinder – Domestic/Consumer

Price : Price of the cylinder.

4. tblStock : Keeps record of Stock.

CurrCommercial : Current stock for commercial cylinders

CurrDomestic : Current stock for domestic cylinders

DefectsCommercial : Stock for defective commercial cylinders

DefectsDomestic : Stock for defective domestic cylinders

5. tblStockTrans : Keeps record Stock arrival.

DoA : Date of stock arrival.

Domestic : No. of Domestic cylinders added in stock

Commercial : No. of Commercial cylinder added in stock

Hardware/Software Specifications

Hardware Requirements

There are very few hardware requirements of this Gas Agency Management

System (GAMS), let’s take a glimpse on these requirements

Machine Requirements

These machine requirements are to obtain the best output of this project

i. A Computer with at least Pentium III requirements and Printer portii. Graphic card with minimum 24 bit True/High colors

iii. Minimum 128 MB RAM iv. A Printer (colored or black and white)

Software Requirements

These Software requirements should be fulfilled or say these software

should be installed on the computer to obtain the best output of this project

i. Visual Basic 6.0ii. Windows Platform (Windows 9X, ME, 2000, XP)

iii. Microsoft Office (With MS-Access)iv. Printer Driver or Software

There are many points on the basis of which I decided to use Visual Basic

for the development of this project, what are these points lets take a glimpse

on to that

Output/Report Generation

1. Display Consumer Record : User can traverse and view consumer

records using option – MASTER ENTRY CONSUMER ENTRY

VIEW.

2. Display Current Stock : User can view the updated stock at any time by

using option – MASTER ENTRY STOCK ENTRY VIEW

STOCK.

3. Printing Bill : User can print bill of the released gas to consumer by

using option – REPORTS PRINT BILL.

4. Daily Booking Status Report : User can view report of the daily

booking using option – REPORTS DAILY REPORT.

5. Monthly Booking Status Report : User can view report of the monthly

booking using option – REPORTS MONTHLY REPORT.

Validation Checks

While dealing with updation, we stressed on the importance of ensuring that

the source data was error free. This process is called validation of the input

data.

Validation checks while taking input data from the user:

1. While inputting consumer no. from the user while adding new

consumer record, it has to be checked the given consumer no. should

not already exists in the consumer master table.

2. Before making any updation, it has been checked that particular

record is present in the file or not.

3. Digit Check : It has been checked that user should not enter character

instead of digits in numeric fields.

4. While booking the gas it has been checked that the previous gas has

been released. Secondly, consumer can book gas only after 21 days of

booking of previous gas.

5. It has been checked that user must enter data in required fields.

Conclusion

This project is designed to meet the requirements of a Gas Agency

Automation System. It has been developed in Visual Basic and the database

has been built in MS-Access only, keeping in mind the specifications of the

system. Apart from MS-Access we could have also implemented other

database software like Oracle or SQL.

For designing the system we have used simple data flow diagrams.

Overall the project teaches us the essential skills like:

1. Using system analysis and design techniques like data flow diagram in

designing the system.

2. Understanding programming logic and language along with utilities

like reports, forms, queries etc. in Visual Basic and MS-Access 97.
