I. ACKNOWLEDGEMENTS

This project will be prepared by me, with advise of Asist.Prof.Dr. Yalçın

AKÇALI and Asist.Prof.Dr.Nadire Çavuş to be submitted to Department Of

Computer Information Systems.

Also I must thank to my best friends for helping me during my project process.

I have to thank my family for their support in my educational life in Near East

University.

II.ABSTRACT

Generally Electronics shop have a very big problem. This problem can be

II explained as "too much time spend in record of the transactions". Most

commonly feature of this project is easy transaction processing. I achieved this

purpose by providing minimum keyboard usage.

Another thing I have to focus; I plan to sell this software to the other companies

in the same sector. After the acceptance of this project the full version will be

sent again and will be marketed to all the electronics shops.

III.INTRODUCTION

The field of Information Technology is an exciting and ever-changing field. If

you are a life-long learner and want new challenges everyday, it's always a good

idea to think of the program you want to create in terms of its solution. In order

to do this, you must have a pretty solid understanding of the programming

language that you'll be working in and what you can do with it. Then you should

sort out what exactly you're trying to accomplish. What do you want your

program to do?

What problem is it solving? Next, divide the program into its vanous

components. Then decide how those components will fit together to execute the

program. Once all these have sorted out, you can write each part of the program

and put them together. This is the correct way to program.

I used Delphi Programming Language and the Microsoft Access Database to

prepare this project.

I used the Delphi language becouse I believe that languae of Delphi is more

useful and benefical and I'm good this language.

Processes

1. Customer ProcessesRegister customer subprocess (New customer registration)

Update customer subprocess (Existing customer update)

2. Sale ProcessProduct sale subprocess (Making order and confirming)

Cancel Sale subprocess (Cancelling the sales)

3. Stock ProcessStock query subprocess (Checking the available stocks)

Update stocks subprocess (Changing the stock information)

4. ReportsProcess

4.1 Sale reports subprocess (Total sales report)

4.2 Income reports subprocess (Balance of sales and payments)

4.3 Payments report subprocess (Payments list)

5. Supplier Process5.1 Register & Update Supplier subprocess (Registering and

changin supplier information)

5.2 Payments subprocess (Recording the payments to the

system)

V.DESIGN OF THE SYSTEM

EXPLANATION:

The minimum requirements of the system are as follows;

./ Intel Pentium IV processor 2.420

./ 533 Mhz

./ 512MB DDRRAM

./ 80 GB HDD

./ 14'' Monitor

./ Microsoft Windows XP

./ CD-ROM 52xmax

./ 256 MB Graphic Card

./ Modem

The recommended requirements of the system are as follows;

./ Intel Pentium IV processor 3.0

./ 800 Mhz

./ 1 GB DDR RAM

./ 120 GB HDD

./ 256 MB Graphic Card

5

•

./ 17" Monitor

./ Microsoft Windows XP Professional

./ CD-ROM 52xmax

./ Modem

In this project I used the Borland's Delphi as programming technology

because of the Delphi's easy Object-Oriented coding characteristic. And I

used Microsoft Access as database. Because Access's performance is very

good when used on a single computer.

1) PROJECT IDENTIFICATION AND SELECTION

THE AIM OF THE PROJECT :

The aim of the system is to record the daily processes easier and faster.

The system I have proposed will center on making the daily tasks of the

managers and the individual employees completely automated. This will

entail using modem hardware, software or external devices in order to give to

service the advantage and complete customer satisfaction.

THE PROJECT BOUNDRIES

1) System can work on a single PC.

6

. 2) System will not connect to internet so can not update itself

3) System can not communicate with the suppliers because of being

an offline system.

4) Microsoft Access doesn't support multiple users at the same time.

So the users of this system can not use the same tables.

RESOURCE LIMITS

1) System has to be able to scan bar codes for stock and purchase

processes. A bar code scanner is required but I don't have.

2) The project will have a special interface using flash extensions.

Program will start with a login screen and only the authorized user

may have the right to use program.

2) PROJECT INITIATION AND PLANNING

TECHNICAL FEASIBILITY

Necessary Hardwares :

- 1 computer for the manager (necessary)

7

- 1 computer for the repairer. (suggested)

- At least 1 printer (laser printer with coloured cartridge)

OPERATIONAL FEASIBILITY

The manager and the other employees who will use the system must have

at least low level computer using skill for being educated about the

system.

ECONOMICAL FEASIBILITY

System can replace an employee's work on like basic accounting, stock

controlling, statistical report preparing, etc.. So the owner can save at least

one employees' salary monthly. This system will cost for the owner about

1500 at total. This cost includes a computer, a bar code scanner, a printer

with coloured cartridge.

5) ANALYSIS

THE REQUIREMENT DETERMINATION

The requirements made by the owner as follows:

- To increase the speed of operations

- To provide easy and quick Access

- System security

(the users cannot be able to see each others password)

8

- Recording of the repairs daily

EXISTING SYSTEM'S CAPABILITIES

- The Electronics Shop existing system is based on manual.

- The Inventory is written on the ledger notebooks and the stock is being

calculated by using this notebook

- A customer card is held for Customer Relationship Management

NEW SYSTEM'S PROVIDENCES

- New system will help to the user easy and quick search of the

information about all the data.

- A worker can easily record repair informations.

- All the transactions by the customers will be stored in the database.

- Stocks and the sale reports (by graphic) will be prepared with one click

9

DATABASE TABLES

1. Customers :

All the customer knowledge will be stored here.

2. Orders:

The general order knowledge (like customer information and order date)

3. Order Details

The details of an order will be saved here (for example stock code, purchase

quantity, etc..)

4. Payments

The company's payments after purchase will be recorded to this table

5. Stocks

The products which company sells are recorded here part by part

6. Suppliers

The companies which we purchase our stocks are stored here
