Tools Information

Visual Basic 6.0 (Front – End Tool) VB is a program language and development that allows you to

create programs that run under windows operating system. It enable you to develop many different type of application. It is a programming language used to create windows base

application. It makes it very easy to get the user interface of the application

and running it. It is very easy and it provides a very friendly environment while

programming in vb. It provides a vital link to graphics environment and allows you to

develop application base on stander windows features. Dialogue box, command buttons, pulls down menus, scroll bars and selection lists etc.

It also allows crating robust application that fully make use of the graphics, user interface.

By connect with access can be run and terminated through vb 6.0.

_ _______________________________________________Page No. 10

Application Hierarchy Of Vb.

An application is made up forms, controls, modules.

Forms are windows on which you built user interface.

Controls are building of user interface control also called active x control and command button that you used to display information to the user, gather information from the user, and respond to the user action.

Procedures are small routing you write that are callable from anywhere in your application into small components that can be called in many times.

Events in a very important in any windows programming language. An event is something that occurs in response to a user interaction with keyboard or mouse. Events are those messages that the operating system sends to the applications.

System Study

Feasibility Study: To check whether the system once created will be feasible or not. A feasibility study is undertaken to determine the possibility all probability of either improving the existing system or developing a completely new system.

Technical Feasibility: To technical feasibility, it is checked that if the work for

the project can be done with present equipments, software and available personnel.

Cost Estimation

The category of the system is “organic” for this a = 3.2 and b = 1.05 are constant.The size of the system is 2.5 kdl (thousand of delivered line of code).

Initial cost estimation ei = a * (size)b

= 3.2 * (2.5)1.05

= 8.375

Eaf is effort adjustment factor.Reliability is high 1.15Database size is normal 1.00Complexity is very low 0.70Programmer experience is very low 1.29Programmer capacity is normal 1.00Language experience is low 1.07Analyst catalyst is normal 1.00

Eaf = 1.15 * 1.00 * 0.70 * 1.29 * 1.00 * 1.07 * 1.00 =1.11Final cost = ei * eaf = 8.375 * 1.11 = 9.30 pm

Existing System

Introduction

The krishna corporation does not own any existing computerized system currently, but are willing to convert their manual system into computerized system. They do all their transactions annually through record books.

Existing system

In manual system, to add a new customer they have to add records in register.

Suppose customer leave the town or city, so their records should be deleted. They delete their records from master register, which is difficult.

If a customer wants to change his or her address, it is difficult to update or change his or her profile into register.

In manual system it is difficult to maintain the stock. When a customer comes for cylinder refills they have to first check

their validity. Then they will book his refill in the register, which is very time consuming.

In manual system they have to daily update the stock register. Difficulty to see how much cylinder customer, company or company

itself has. Existing system is manual system rather than computerized.

_ _______________________________________________Page No. 16

Problems With Existing System

Entry into different register is very time consuming process. Sometimes it leads to ambiguous records.

It becomes difficult to do the deletion and any modification in the master register.

Updating master register for daily transaction is very tedious job and also very time consuming.

Duplication of records may occur.

Stock management is difficult in using register.

In existing system they are using different types of registers for different purpose.

Work distribution can’t be made easily.

To check customer’s history is difficult.

Probabilities of errors in calculation of bills, stock management etc.

_ _______________________________________________Page No. 17

Introduction Of Proposed System

This system involves

When a customer request for a gas refills, first check for his validations, prepare bills and handle those bills to particular deliveryman for delivery.

This system maintains customer’s all type of records.

It handle customers all requests for booking, gas refills and to provide them in time.

It also includes preparation of different reports.

_ _______________________________________________Page No. 19

Features Of Proposed System

Manual work has to be reduced and result to be received quickly. To speed up the operation and decrease manpower, high cost. Increase security, speed, storing and accuracy. The customers have to face only one person at the counter for booking

cylinder. Managing and maintaining data becomes easier and cost effective due

to very high amount and reliability of storage space available in the proposed system.

The system has been developed under microsoft visual basic 6.0 as a front-end and microsoft access as a back-end tool.

Requirement Analysis

As we have decided to develop a new system now it is a time to determine the new requirement for the new system. As the user is the most important part of any system it is required to find the users requirement to develop a user friendly system rather than having develop a developer friendly system.

the outputs required by the user that must be included into the proposed system are as follows.

The work for he particular user must be personalized. The customer information must be entered on such a way that it

is easier for user to understand. Daily reports and monthly reports are printed. Bills are printed as in required order. The user must be provided ease if he wants to switch from one

application to other at a time.

Data Dictionary

Data dictionary is a store of information about the data in database. The dictionary defines the name, description, source of data, users of data, and keywords in data, formula to derive the data specification and such other details. Data dictionary brings common understanding of the data in the organization RDBMS provides software to create the dictionary. Use of data dictionary enforces the standards of processing, usage’s application and documentation in the organization.

Data dictionaries are an integral component of structured analysis, since data flow diagram by themselves do not fully describe the information about the system. The data dictionary provides additional information about the system.Description of all data used in the system is given in a data dictionary.

Analysts Use Data Dictionary For Five Important Reasons.

1) To manage the detail in large systems.2) To communicate a common meaning for all system elements.3) To document the features of the system.4) To facilitate analysis of the details in order to evaluate characteristics and determine where system changes should be made.5) To locate errors and omissions in the system.
