异构数据库集成中的变化捕获方案设计

Change Capture Model Design in Heterogeneous Database Integratio n

数据库集成是分布式环境中的一项关键技术。由于数据库异构现象越来越普遍,研究异构数据库集成无论在理论还是实际应用上都具有非常重要的意义。详细比较各种常用变化捕获方法之后,提出一种变更轨迹表的设计方案。

Database Integ ration is a pivotal technology in distributed computing. By both practical and theoretical, research in heterogeneous database integration makes important sense for more and more heterogeneous databases. Based on several theories on capture change, this paper puts forward a design model on capture change trance table.
