摘　　要：文章通过对树形目录继承权限功能的特点进行分析,定义了一种通用的树形目录继承权限功能数据模型。该数据模型应用广泛,不限定编程语言,应用系统架构和具体的数据库类型,只要满足模型定义的数据表结构、视图和表值函数,即可简单快速地在系统中实现树形目录继承权限功能。Through the analysis of the features of inheritance authority funetion of a directory tree, the paper defines the data model of inheritance authority function of a common directory tree. The model is widely applied because it isn＇t con- fined to program languages and applies system framework and concrete database. If data sheet structure, view and tabular function of model definition are satisfied, the inheritance authority function of a directory tree is applied in system easily and quickly.
