Design And Implementation Of Computerized Price Checking System

abstract of Design And Implementation Of Computerized Price Checking System

The business-to- consumer aspect of an online shopping is the most visible business use of the World Wide Web. The primary goal of an online shopping site is to sell goods and services online. This project deals with developing a computerized price determining system for shop ware. It provides the user with a catalogue of different goods and services available for purchase in the store. In order to facilitate online purchase a price checking website is provided to the user. The system is implemented using a 3- tier approach, with a backend database, a middle tier of Microsoft Internet Information Services (MIIS) and PHP, and a web browser as the front end client. In order to develop an e- commerce website for online shopping, a number of Technologies must be studied and understood. These include multi- tiered architecture, server and client side scripting techniques, implementation technologies such as ASP.NET, programming language (such as C#, VB.NET), relational databases (such as MySQL, Access). This is a project with the objective to develop a basic website where a consumer is provided with a price checking application and also to know about the technologies used to develop such an application.

chapter 1 of Design And Implementation Of Computerized Price Checking System

1.0 Introduction

With the write of their great capacity and speed in technology, computers have helped workers in business perform their jobs more efficiency, since their introduction in the 1980s. Routine functions such as sending memos can instead be done by email. Workers can research information from the Internet with a click of the button. The importance of computers in business also has many other positive benefits in the work force. Computers also help the businessman save time. For example, a businessman can write a report, do a spell check, edit it and distribute the report in just a few hours–even long distance. Previously, companies used typewriters for reports where redactions were made on various pages. These pages then needed to be retyped until the report was error free. Managers then needed to copy the reports and mail them to employees in different cities. Consequently, the report writing process took much longer with a typewriter than a computer. Also, utility and cable companies can pinpoint a customer’s problems more readily with computers.

It is no wonder, insecure, that many managers, planners’ administrators, educationists, researchers, chief executives and business men now feel an urgent need for computer in their respective organization. In the save view, the objectives of this project is to incorporate computer into the processing of information at LEADMART STORES. Computerization of the store can remove wastage, guarantee quick service at service points of vital importance to the public and improve productivity. Such computerization effort often costs for less than the money and time it will save both the public and the organization.

1.1 Statement of the Problem

Every organization (LEADMART STORES) encounter numerous problems, which include keeping goods, maintaining, checking and having goods account records for goods in stock.

Despite the good maintenance in the manual stock control system at LEADMART STORES, there will arise great inefficiency in its accounting system, as well as its record updating system.

However, the main aim of this study is to incorporate computer into the daily operations of the store with reference to mainly it’s accounting system, as well as its stock control system and its day to day commercial operations.

With introduction and application of computer into the operations of the STORE the organization will be able to improve dramatically on its daily information and accounting system.

The above problems discovered therefore prompted to a software design to be able to add to existing stock and delete goods in stock collectively referred to as updating, as well as producing an accurate accounting system for the STORE.

1.2 Purpose Of The Study

The purpose of this study is to design and implement a system that will eliminate the above problems such as misplacement of vital information, documents, records, duplications of efforts etc.

A computerized accounting system and organization allows the user to enter the transaction into the program at once, and all accounts are updated as necessary without delay and unexpected mistakes of records and transactions.

1.3 Objectives Of The Study

The aims and objectives of this project report is to study how the organization (LEADMART STORES) operational aims and other activities and how they are executed.

It saves time;in cases where a shop maintains all data manually, its manager must reconcile each sales receipt with every piece of physical inventory. Depending on the size of the establishment and how many different products are sold, this can be a daunting and time consuming task.

To ensure accuracy in the inventory system;when an inventory list is maintained by hand, the margin of error widens with each update. If one mathematical calculation is wrong or one typo is made, disaster may occur. For instance, if a clerk accidentally adds a zero to the end of a purchase order, a business could potentially end up paying for 10,000 units of merchandise as opposed to the 1,000 that is actually needed.

In areas of misplacement of vital documents a computer will be used to record, store, retrieval of large volume of documents; which will reduce the duplications efforts due to in-accuracy in activities and time taken in locating of files when it is required for processing.

1.4 Scope Of The Problem

The researcher is limited to the study of computerized price determining system (LEADMART STORES).

The study is also limited to the limitation that is being acquired from (LEAMART STORES), more information were gathered from the write-ups of the existing system of back-up the study and design of the new system.

1.5 Limitation Of The Study

One to lack of time and resources, the study is limited to certain area concerning problems being encountered and gathering of information’s on how goods are being sold or kept and how to process them using a computer.

1.6 Assumption

This research was carried out with the assumption of the combusting that might arise in tackling stocks problem and computation inefficiencies.

For this purpose, the assumption reached was to design and implement a price determining software package that will eliminate and arrest any difficulties that involved in manual computation.
