分布式间歇同步数据库的研究与实现

摘要

The distributed intermittently synchronised database is characterised by mobility , intermittence and weak reliability in the aspects of the data communication .Apart from that it also has the features of the discrete distribution , heterogeneity in the aspects of data itself.According to all these characteristics , in this paper we present both the data synchronous process model and its safeguarding mechanism of the database.Furthers more, we also prove its feasibility by applied examples .%针对分布式间歇同步数据库具有移动性、间歇性、弱可靠性等通信特征，以及数据离散分布、异质和异构的特点，提出分布式间歇同步数据库的数据同步过程模型及其保障机制。并通过实例应用，证明了该方法的可行性。
