A computerized information system has at least one server (100) and a plurality of workstations (201-203) operatively connected to said server. The server is arranged to provide access for users (510-512) of said work stations to digital data entities (401-406) stored in a storage device (400). The system has means (310) for maintaining an authority profile assigned to each user, wherein the authority profile comprises an access level parameter and at least one of a geographical location parameter, an organizational position parameter, a product type parameter, a business unit parameter or a personal competence parameter and wherein the authority profile relates the user to a node (501-509) in a hierarchical structure (500). The system also has means (320) for controlling each user's accessibility to the digital data entities (401-406) in dependence of the authority profile. Additionally, the system has means (330) for allowing a user (512), the authority profile of which comprises a designation of said user as administrator of a particular node (504), to dynamically modify, create or delete authority profiles for users related to nodes (504, 506-509) in the hierarchical structure subordinate or identical to said particular node (504). |
