A Project on Stock Maintenance

Stock maintenance system

ABSTRACT


The main objective of this project is to overcome the work load and time consumption

which makes the maintenance of the stock in an organization as a tedious process. This

project provides complete information about the details of the stock to the users. This

project identifies the amount of stock available,the product that is purchased faults in the

product,products that are replaced,products that have been sold,and the date at which the

products are bought and sold in a particular concern.Separate modules have been created

for purchasing, viewing stock details,selling, details and delivery details.As a whole

,marketing process can be improved if stock has been maintained properly.

This project is developed with help of visual basic 6.0 as a front end and oracle 9i

as back end. The application software Rational Rose is also used.

1. INTRODUCTION

1.1 PROBLEM

Stock Maintenance gives an idea about how products are maintained in the

particular concern. The products that are to be purchased, the products that are to be sold

are maintained here.

This project also gives idea about the faults in the purchased product and the products

that are to be replaced also been given. Further some additional details of the current

stock that is available in the store is also given.

Stock maintenance in this project is done in an authorized way. The password and user id

has been set here. As a whole the marketing process can be improved if the stock is

maintained properly.

1.2PROBLEM DEFINITION:

The stock has to be maintained properly since the whole marketing process can be

improved. Stock maintenance in this project gives the idea about how products are

maintained in a particular concern.

The stock details which includes the amount of stock available, the stock is to be

purchased, the date or the time it is being bought or delivered, the amount that is already

available are maintained in this project.


The stock maintenance in this project is understood by goin through the modules that is

being involved. The whole economic status is being improved properly if stock is

maintained.


2. SOFTWARE TOOLS

2.1 MS-VISUAL BASIC:

Visual Basic 6.0 is fastest and easiest way to create single user and client/server

applications for Microsoft Windows. Visual Basic 6.0 provides complete set of tools to

simplify rapid application development both for the experienced professional and new

windows programmers.The “Visual” part refers to the method used to create Graphical

User Interface.The “Basic” part refers to the BASIC language used by more

programmers than any other language in the history of computing. It is an ideal

programming language for developing sophisticated professional applications for

Microsoft.

2.2 ORACLE 9i:

Oracle 9i makes most necessary conversion to the code automatically when we

convert our data base. However the conversion process makes some changes to code

that need to aware of, and there are some additional changes that must made in order to

run the application successfully in oracle.

3. METHODOLOGY


3.1 CONCEPT

Storing of information about the stock values and updating the stock values for

each organization which is using this system, keeps track of all the information about the

stock exchange that are made by the customers, having registration feature of adding up

new customers to the organization are provided in this system.

3.2 DATABASE CONNECTIVITY:

The front end used for implementation of this project is Visual Basic 6.0 and the

back end that is used for this project is Oracle9i.The database connectivity between

Visual Basic 6..0 and oracle9i is provided by using Microsoft ADO Data control

6.0(OLEDB). Thus the project makes use of the internal feature of ADODC for

communicating with the database and this is responsible for transfer of data to and from

the table from and to the front end.

A term used to a database or database server used as a source of data. ODBC data

source are referred to by their Data Source Name (DSN). Data sources can be created by

using the windows control panel or the register database method. A standard protocol that

permits application to connect to a variety of external database servers or files. ODBC

drivers used by the Microsoft database engine permit access to Microsoft SQL server

and several other databases.

To add ADO data control to the toolbox go to the components and select

Microsoft ado Data control 6.0(OLEDB). There are three different options insetting

connection string. They are as follows

1. Use data link file : any data link file already stored can be specified.

2. Use ODBC Data source name : any ODBC DSN can be specified.

3. Use connection string : choose build to create a new connection String

specifying the OLEDB provider.

4.SYSTEM REQUIREMENT

Strorage Capacity : 20 GB

RAM Capacity : 512 MB

4.2 Software Requirements:

State diagram shows that the sequence of states that an object goes through during

its life in response to outside stimuli and messages.


5.1.4 ACTIVITY DIAGRAM

Activity diagram is a variation or special case of a state machine in which

the states are activities representing the performance of operations and the transitions are

triggered by the completion of the operations.

8. CONCLUSION AND FUTURE ENHANCEMENT

8.1 CONCLUSION

Thus the project gives the detailed explanation about how stock is maintained in

an organization.it also gives idea about how stocks are to be purchased and how to be

maintained in a company.

8.2 FUTURE ENHANCEMENT

There is always a room for the improvement in any software package, however

good and efficient it may be. The important thing is that the software should be flexible

enough for further modifications.

In future we will enhance this project by making our system to store the details of

the customer such as the house address to make the door delivery which is an easy and

quick way.
