摘 要
随着现代科学技术的迅猛发展,计算机技术已渗透到各个领域,成为各行业必不可少的工具。在当今激烈的市场竞争中,让顾客享受既实惠又快捷的购物服务是商战中制胜的一大要素。改革开放的今天,各种大型超市林立,超市已成为消费者日常活动的主要场所。而超市商品也非常之多,建立一套方便快捷的超市收费系统是企业必然要解决的一个问题。系统采用的编程工具是Delphi 7.0版本与Access作为数据库。系统分为前台系统和后台系统,其中,前台系统提供了很方便的商品销售收费功能,这其中包括会员卡用户可享受八折优惠。而后台系统则提供了一些商品管理功能,如采购入库,库存盘点,出库明细等模块。
本文主要介绍超市收费系统的运行环境、功能作用、设计的方案等各方面的内容。论文共分为五大部分。第一部分简要叙述了系统的基本概况。第二,三部分分别从软件工程的要求出发,首先进行问题的定义,其次进行可行性研究,分别从技术可行性,经济可行性和操作可行性进行分析,然后进行总体设计和详细设计,并阐述了如何实现具体功能。第四部分为系统调试,其中包括子模块测试和总体测试。

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.
