超市收費(fèi)系統(tǒng)的設(shè)計(jì)與實(shí)現(xiàn)
摘    要
 隨著現(xiàn)代科學(xué)技術(shù)的迅猛發(fā)展，計(jì)算機(jī)技術(shù)已滲透到各個(gè)領(lǐng)域，成為各行業(yè)必不可少的工具。在當(dāng)今激烈的市場(chǎng)競(jìng)爭(zhēng)中,讓顧客享受既實(shí)惠又快捷的購(gòu)物服務(wù)是商戰(zhàn)中制勝的一大要素。改革開(kāi)放的今天,各種大型超市林立,超市已成為消費(fèi)者日?；顒?dòng)的主要場(chǎng)所。而超市商品也非常之多,建立一套方便快捷的超市收費(fèi)系統(tǒng)是企業(yè)必然要解決的一個(gè)問(wèn)題。系統(tǒng)采用的編程工具是Delphi 7.0版本與Access作為數(shù)據(jù)庫(kù)。系統(tǒng)分為前臺(tái)系統(tǒng)和后臺(tái)系統(tǒng)，其中，前臺(tái)系統(tǒng)提供了很方便的商品銷(xiāo)售收費(fèi)功能,這其中包括會(huì)員卡用戶可享受八折優(yōu)惠。而后臺(tái)系統(tǒng)則提供了一些商品管理功能，如采購(gòu)入庫(kù)，庫(kù)存盤(pán)點(diǎn)，出庫(kù)明細(xì)等模塊。
    本文主要介紹超市收費(fèi)系統(tǒng)的運(yùn)行環(huán)境、功能作用、設(shè)計(jì)的方案等各方面的內(nèi)容。論文共分為五大部分。第一部分簡(jiǎn)要敘述了系統(tǒng)的基本概況。第二，三部分分別從軟件工程的要求出發(fā)，首先進(jìn)行問(wèn)題的定義，其次進(jìn)行可行性研究，分別從技術(shù)可行性，經(jīng)濟(jì)可行性和操作可行性進(jìn)行分析，然后進(jìn)行總體設(shè)計(jì)和詳細(xì)設(shè)計(jì)，并闡述了如何實(shí)現(xiàn)具體功能。第四部分為系統(tǒng)調(diào)試，其中包括子模塊測(cè)試和總體測(cè)試。

The Design and Realization of Supermarket Charging System
Abstract
With the rapid development of modern science and technology, computer technology which has penetrated into all fields becomes indispensable for every industry. Beneficial and effective services for customers are a key point to win in commercial trade in market competition. Under the policy of reform and opening-up, different kinds of supermarket loom so large, which make the supermarkets, be the main place to active in daily life. But due to various and numerous goods, how to build a convenient and fast charging system is a problem which is must resolve. The programming tool of the system adopts Delphi 7.0 and uses Access as database. The system divides into two parts, the foreground and the background. The foreground offers convenient function for goods sale fee and the member card users who can enjoy a 20% discount. At the same time, the background system gives some function for goods' management, such as purchasing and warehousing, stock-taking, and the details about the out housing and so on. This system runs under the practicability of software and the convenient operate from the beginning to the end.
This thesis mainly introduces the environment, function and design plan of the supermarket charge system. It is totally divided into five parts. The first part synopsis described the basic general situation of this system. To begin with the software engineering requirements, I first make a definition of the question in the second and third part, then do some practicable research, analysis from technical, economic and operational feasibility, and design for the totality and detailed, with expounding how to achieve its concrete function. System adjusting is discussed in the fourth part which still includes the Sub-module test and overall test.
Key words: charging; sale; supermarket
