Abstract:
A method of accessing a substantial directory for storing and managing data, comprising the steps of:(a) inputting a view search instruction for manipulating data, which is defined by a combination of arbitrary class and attribute requested by an application; (b) translating the view search instruction into a directory manipulation instruction for manipulating one or a plurality of substantial directories according to a prescribed view definition which defines application dedicated view as a set operation with respect to the substantial directory; (c) extracting entries from the substantial directories using the directory manipulation instruction to derive an entry set; (d) generating a directory set operation instruction including the entry set and the set operation based on a relational algebra defined in the view definition; and (e) generating a tree-structured hypothetical directory corresponding to the view search instruction of the application, the hypothetical directory being customized per application so as to be directly utilized by the application, by executing the directory set operation instruction per every operation type to the entry set.
