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 Name Address Pin Phone DoC Cylinders CylinderType

: : : : : : : :

Unique code allotted to every consumer. Name of the consumer. Address of the consumer. Pin code of the location. Phone no. of the consumer. Date of connection. No. of cylinders consumer have. Type of cylinder – Domestic/Commercial

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

Slno ConsumerNo DateofBooking DateofRelease IsReleased Remarks

: : : : : :

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. ii. iii. iv.

A Computer with at least Pentium III requirements and Printer port Graphic card with minimum 24 bit True/High colors Minimum 128 MB RAM 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. ii. iii. iv.

Visual Basic 6.0 Windows Platform (Windows 9X, ME, 2000, XP) Microsoft Office (With MS-Access) 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
