摘要/Abstract

摘要： 企业信息化在高速发展的同时也产生了很多需求,异构数据库间的数据集成和数据同步就是其中一个亟待解决的问题。基于extensible markup language实现了异构数据同步模型,通过应用上的分析,设计了在传输速率和传输稳定方面改善性能的方法,从而建立了基于P2P的异构数据同步模型,该模型采用extensible markup language技术和面向服务技术屏蔽数据的异构性,通过触发器和控制表的方式实现了差异更新,并利用基于最短路径P2P算法实现增量提取和传输优先级,从而增强了传输的效率和可靠性。

关键词: 数据同步, 最短路径算法, P2P, extensible markup language

Abstract: The existing problems in data integration and data synchronization were analyzed, especially the requirements of heterogeneous data synchronization and efficient transport. A heterogeneous database data synchronization model was given. By transferring into Extensible markup language files, the difference between heterogeneous data sources was shielded. A P2P-based optimal algorithm ensures real-time transports, which is essential to business applications. A data synchronization tool was developed and used in real applications. By comparing the system performance, it was shown that this tool can solve a heterogeneous problem and can keep high speed transmission when the network situation was not so good.

Key words: shortest path algorithm, peer to peer, extensible markup language, data synchronization
