摘要： There is disclosed a scheme for accessing data management directory which is capable of achieving easy and flexible data access which are managed in substantial directories from respective applications by constructing substantial directories which sort and manage the location of data accumulated on the network and access information independently from the applications, and then sharing and integrating a group of these substantial directories to show a directory structure which is easy for the applications to utilize. In this scheme for accessing data management directory, a view search instruction for manipulating data, which is defined by a combination of arbitrary class and attribute requested by an application is inputted; the view search instruction is translated into a directory manipulation instruction for manipulating one or a plurality of substantial directories, according to a predetermined view definition; entries are extracted from the substantial directories using the directory manipulation instruction to derive an entry set; and a directory customized corresponding to the view search instruction of the application is generated based on a combination of the class and the attribute as a result of the set operation, by applying a set operation defined in the view definition to the entry set.

摘要： An information retrieval scheme using classification trees with respect to a plurality of information sources connected to a network is disclosed, where each classification tree having a hierarchical structure defined in terms of entries. In the information retrieval apparatus, classification tree class information for each classification tree class defined among entries constituting each classification tree is managed, where each classification tree class information indicating retrieval condition parameters for each classification tree class. Then, the information retrieval is controlled by receiving from a user a retrieval request indicating a retrieval target entry that was obtained by the user by tracing the classification trees, generating retrieval commands with respect to selected information sources among said plurality of information sources by referring to each classification tree class information corresponding to the retrieval target entry that is managed by the class definition unit, obtaining a retrieval result of a retrieval with respect to the selected information sources using the retrieval commands, and returning the retrieval result to the user.
