Database management system

摘要

The data management system has a generic data base (GDB) with a central control system (CU) and at least one generic data module (GM), a central access control system (CTCC) incorporated in the central control system, controlling access to the user data in the central plane. A local access control system CTCL) is incorporated in the generic data module, for controlling access to the user information in the local plane, with corresponding operation of the central access control system. A user specific data module system (ADB) has at least one specific data module for providing specific data types from the generic data module, with a user specific access procedure.
