ABSTRACT

　　The article simply elaborated the supermarket sale system development background, the design goal as well as the service flow, carry on the market demand in view of this system the analysis, the function description, the database design, in detail described the over all system design mentality and its the performance history. The full text according to the life cycle which software develops, divides into stage and so on feasibility study, demand analysis, system design, detailed design, used the Delphi7.0 program language and SQL the Server 2,000 data bank technologies, the application dataflow chart, the E-R chart, the database table and so on the tool clear demonstration design process.
　　The article realizes the supermarket sale system from conforms to the operation easily, the contact surface is friendly, nimbly, the safe request embarks, completes the supermarket sale the entire process. This system tries to move good, may provide the science reliable management function, can realize the commodity records management, the member manages, basic function and so on information management, routine work management, transaction, statistical report form, can accurately record with the consult related supermark-
ket management mass datas, can carry on the profit analysis, helps the supermarket operator to grasp with the analysis marketing situation, promptly makes the correct decision-making, basically has achieved the anticipated target.
