摘要： A system for managing an object-oriented database in response to a request issued from an application program includes a database for storing therein both of a class having a definition of an object and an object generated from the class; a generating unit for generating a class and a plurality of attributes based on class definition information and attribute definition information, which are designated by the application program; another generating unit for generating an object to store an attribute value corresponding to the class definition information in accordance with the class definition information, the object generating unit including a-storage control unit for storing the attribute value related to a normal attribute into one storage unit area of the database when the request issued from the application program is related to the normal attribute, and for storing the attribute value related to a clustering attribute into another storage unit area of the database when the request issued from the application program is related to a clustering attribute; and acquiring unit for acquiring information corresponding to an identifier of an attribute required by the application program from any one of the one storage unit area and the another storage unit area, and for storing the acquired information into a memory area.
