Abstract: A system for distributing processing between terminals (T.sub.1 .about.T.sub.n) connected via a communication network (30). Each terminal (T.sub.i) is provided with at least one method group (32) and a memory unit (34) to store data files. An originating terminal, e.g., terminal (T.sub.1) accesses data elsewhere in the distributed system by generating a message. The message includes a terminal code identifying an object to access a terminal (T.sub.2) to execute an object, a method code identifying a method for accessing the data and a command name containing or identifying the desired data. The terminal, e.g., terminal (T.sub.2), containing the desired data, decodes the message and accesses a data file in the memory unit (34) containing the desired data identified by the command name. The message may also include a selector and reset conditions which control the sequence of data processing in the terminals (T.sub.0 and T.sub.n) so that the processing of the originating (T.sub.1) and data accessing (T.sub.

Abstract: An automatic support tool generating system includes a knowledge acquisition tool for acquiring knowledge from answers received in response to questions generated by the knowledge acquisition tool, and a database for storing the knowledge acquired by the knowledge acquisition tool as data and for forming a knowledge data group, where the knowledge acquisition tool acquires, based on attribute data which are obtained as the answers, a design support knowledge data group used for generating a design support tool which is necessary to make a desired design.

Abstract: In a computer system, a device which takes the real area as the objects (1-1, . . . ) and selects dynamically the real data (11) as the actors (2-1, . . . ) and the method (42) for processing such actors, is provided, objects (1-1 . . . ) are formed by capsulating the instance including real data (11) as the parts and the method (42) and thereby data processing is carried out mainly with the actors (2-2 . . . ), namely the real data. In view of dynamically forming an object (1-2) capsulating the real data (instance) (11) and the method (42), a part called the object sensor which indicates the real data (11) given the meaning by the command is prepared, the command is sent and received in the data processing means by the object modeling the real area, and thereby new type and practical object-oriented data processing just suitable for processing of multi-media data, distributed processing of data base and processing of network system can be realized.

Abstract: A database system includes a communication network, and a plurality of nodes. Each node includes a data storage device, a management part managing a status of the data stored in the data storage device, and a data storage request part for generating an alternative data storage device assignment request for requesting at least one of other nodes among the plurality of nodes to store data in the data storage device of the other node via the communication network when a predetermined condition is satisfied.
