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.
