Recently, the diversified types of companies have been trying to cooperate among them to cope with the dynamic market and thus integration of their DBs with heterogeneous requirements is needed. But the conventional centralized approach has problems of fault-tolerance, real-time property and flexibility. Here, the autonomous consistency technique in(More)
The Autonomous Decentralized Systems (ADS), born in Japan 30 years ago, have technologically evolved in communication networks, information systems, and control systems. It has been applied in many actual systems, and it has progressed in standardization activities. IEICE and IEEE published joint Special Sections on " Autonomous Decentralized Systems " in(More)
The Autonomous Decentralized Database System (ADDS) was proposed to flexibly cope with company's requirements in dynamically changing environments. In the ADDS each node holds a copy of database, and update requests to the data items in a node can be processed independent of other nodes if the requested amounts are less than the allowances that are called(More)

The autonomous decentralized DB system (ADDS) has been proposed to avoid the single point of failure (SPOF), where the databases are replicated among distributed subsystem nodes, and update operations to the numerical values of the DBs are independently performed at subsystem nodes within their allowances (called allowance volumes). If the request is within(More)
