本系统采用Visual Foxprow 5.0编写,面向对象可视化编程,使系统的开发工作适应目前的流行趋势。设计时采用了常用的自顶向下的瀑布式结构化设计方法。各子系统具有独立的数据库结构，设计时力求简单易用，便于维护。各模块为平行关系，彼此间无直接的参数联系，也无库的交叉关联，从而保证各子系统可以单独运行。-the system using Visual Foxprow 5.0 preparation, visual, object-oriented programming, allowing the system to adapt to the current development trend in fashion. Used in the design of the popular top-down waterfall structure design method. The subsystem is independent of the database structure, design sought to be simple to use, easy to maintain. Each module for parallel relationship between the parameters are not directly linked, nor for the cross-linked, so that the subsystems can be run separately.
