  • Patent number: 5261098
    Abstract: In a computer system where applications and data manipulated by the applications are implemented in an object oriented manner, an object type and its deriving attribute are stored as an entry in a table having an identifier. The object type table is in turn stored in a database. Similarly, the object type and its attribute values having corresponding attribute identifiers are stored as an entry in a table having an identifier. The object type attribute table is in turn also stored in a database. An object type deriving manager and an object type attribute values obtaining manager corresponding to the object type table and the object type attribute table are provided for deriving object type and obtaining object type attribute values respectively. A row getting interface routine and a column getting interface routine are provided for invoking the functions of the object type deriving manager and the functions of the object type attribute values obtaining manager.
