In the recent years, the society has suffered several changes in its ways and methods of consuming. The companies are providing services through the Internet to large number and uncertain customers. The customers require one-click service and their preferences changes dynamically. Autonomous Decentralized Database System (ADDS) is proposed as a system architecture in order to realize assurance in distributed database systems that support e-business. A background coordination technology, performed by an autonomous mobile agent, is devised to adapt the system to evolving situations. The system can achieve timeliness by allocating the information in advance among the sites that has different time constraints for updating. Further, the system is provided with an autonomous reconstruction technology to coordinate the heterogeneous requirements when the size of the system increases. Based on a autonomous restructure mobile agent (RMA), which autonomously determines how many sites and which sites should be restructured to improve the response time, this technique can adapt the system to the evolving situation dynamically. Thus, the assurance of the system can be maintained. A simulation shows the effectiveness of the proposed technology.
