【正文】 on smoothly.This system is the utilization uses Microsoft Corporation Visual the FoxPro development kit to take the backstage database management system, The design database and develops this product. This system provides using the system controls and the module massively, from initial user demand analysis, The database structural design, has all given each step design detail to each kind of form manufacture. This system contact surface uses the Windows system the general contact surface, every has certain puter operation knowledge people all to be possible convenient, to use this system freely. This article detailed introduction system manufacture entire process. According to the software engineering design concept, uses the life cycle law to carry on the entire journey development, including demand analysis, system design, system detailed design and so on.
