随着信息技术的进步，具有不同需求的不同类型的企业之间需要相互合作，以在不断变化的市场中获得更多的利益。这就是异类电子商务。为了应对这类电子商务，需要一个能够有效实现异构性、实时性、灵活性和容错性的平台。本文主要研究电子商务中不可缺少的数据库领域。在此基础上，提出了由两种技术组成的自主分布式数据库系统。在第一种方法中，引入了允许体积(AV)的概念，而在第二种方法中，给出了一个移动代理(MA)来调整每个站点的允许体积。由于MA总是在站点之间移动，并且每个站点总是可以自主地与MA协商AV，所以系统可以实现保证。并通过仿真验证了该系统的有效性。
Due to the advancement in the Information Technology, different kind of companies with heterogeneous needs have had the necessity to cooperate among them to get more benefit in a continuous changing market. That is heterogeneous e-business. In order to cope with such kind of e-business, a platform which can effectively realize heterogeneous needs, real time, flexibility and fault-tolerance is needed. This paper focuses on the database field that is indispensable for the e-business. Thus, it proposes Autonomous Decentralized Database System, which is composed of two techniques. In the first one, the concept of Allowable Volume (AV) is introduced, while in the second one, a Mobile Agent (MA) that adjusts the AV of each site is shown. Since the MA is always moving among the sites, and each site can always negotiate AV with the MA autonomously, the system can realize assurance. Furthermore, the effectiveness of the proposed system is shown by simulation.
