摘要
无穷级目录类型的数据库模型在实际应用过程中非常频繁,适用于层次性非常强的一些应用系统,所要求的层次数常常是不等长且要求无限长,提出了一种非常通用的数据模型,能适应灵活多变的数据要求,给出相应的关于delphi的代码实现。
The database model of infinite grade of catalogues is widely used in the practical application process ,and is adapted to the application system with greatly obvious levels and the level grades to be required is differ but infinite. This paper presents a widely used data model,which will be adapted to the various data requirement, and gives the relative code implementation about delphi.
