A data storage and management apparatus for storing and managing data of an object as a persistent object in a data storing system. When storing an object in the data storing system, information on complexity of data of at least one attribute of the object is recorded in the apparatus, and data of each of the at least one attribute of the object is stored in a first table in the data storing system when the data of the attribute is not complex data, and in a second table in the data storing system when the data of the attribute is complex data. When manipulating data of an attribute of the object in the data storing system, the above information on complexity is referred to, and manipulation is performed on the first table when the data of the attribute is not complex data, and on the second table when the data of the attribute is complex data.

Data management apparatus storing uncomplex data and data elements of complex data in different tables in data storing system

An object-oriented type information managing system includes a network control system and a network managing system, the network control system includes an upper control object, and the network managing system includes a plurality of processes each having one or more objects. One object is used as a relay object for receiving a request message from the upper control object, and other objects are used as request message destination objects (or, control target objects) managed by the relay object. Each destination object returns a response message. Further, at least one process in the plurality of processes comprises a reply object for receiving the response messages sent from the destination objects and directly sending them to the upper control object.
