一种基于触发器的数据同步系统的研究及关键技术实现
RESEARCH ON A TRIGGER-BASED DATA SYNCHRONISATION SYSTEM AND THE IMPLEMENTATION OF KEY TECHNIQUES
摘要
Abstract
Aiming at the demands of data synchronisation and sharing inside the distributed database and among different business systems, a method of implementing data synchronisation system is proposed in this paper. Firstly, various kinds of data synchronisation mode and their processes are analysed; secondly, the data synchronisation frame and the implementation flow are presented; finally, the implementation of trigger-based data change acquirer is emphatically discussed. The data synchronisation system adopts such a the way in which the data change is captured only by recording the primary key and considers the operation of table by the application program as well. Thus, the influence on application program execution efficiency by synchronisation process is limited as much as possible.关键词
