| Abstract: | Through the analysis of the features of inheritance authority function 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 confined 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. |
