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 Company
Sri Guru Singh Sabha Institute of Information Technology (SGSS-IIT) is an Associate institute of Guru Nanak Dev University, Amritsar "GNDU is a 35 Years old UGC approved Government University" under the management of Sri Guru Singh Sabha (Regd.) Gurdwara Jangpura Extension. At the institute, it is our goal to enable under graduate and graduate to possess a strong theoretical, practical and experimental foundation in the basic discipline of IT and Management. The Institute has been paying special attention to the development of student in professional values of fairness, objectively, comparison, commitment and super coordination. They are turned to the needs and demands of business and industry not only through the state of art inputs but also through carefully designed co-curricular programmes like leadership and personality development programme.

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.

Working of the Project/User Manual
Adding new consumer record : User can add new consumer records in
table- tblConsumer from option – MASTER ENTRY CONSUMER
ENTRY ADD NEW.
Modify consumer record : User can modify any existing consumer
records using option – MASTER ENTRY CONSUMER ENTRY
MODIFY.
Delete consumer record : User can delete any existing consumer records
using option – MASTER ENTRY CONSUMER ENTRY

using option – REPORTS MONTHLY REPORT.
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.
