摘　　要：论述了基于触发器、日志表和可靠远程复制数据算法实现的数据集中系统,系统由数据捕获和数据复制两部分组成。可以在UNIX下可靠、高效地运行。该系统与应用取向基本无关,可以集中各种应用系统的数据,并能够自动检测网络连通性,且具有较强的容错机制。This paper describes a reliable and efficient data concentrating system (DCS) based on the triggers, log tables and an algorithm that can update remote data reliably. The DCS running under UNIX includes two parts: data capturing module and data sending module, respectively. The main contribution of the DCS is that it is independent of specific application, so it can gather all applications data transparently. Moreover, the DCS can detect the availability of network and remote host automatically and tolerate many unexpected defaults such as a host crashing, network breaking suddenly, etc.
