摘要 该文首次提出了主数据对象和影子数据对象概念模型,并结合主动数据库中“事件-条件-动作”的数据触发机制,利用多个通讯代理之间协同技术,解决了多个节点群中大型异构数据库之间的数据一致性维护问题。 The pa per presents for the first time a concept model of the main data objects and t he shadow data objects,and makes it possible for the model to maintain the cons istency of data in heterogeneous database through the Event-Condition-Action t riggering mechanism of the active database and the collaborating technique of co mmunication agents.
