摘要: 以煤矿系统为背景,利用DTS工具和.NET Remote框架,分析、设计并实现了一种由数据源端发起的数据抽取方法。该方法可将分散在不同地理位置上的操作型数据源加载到数据仓库中,并且考虑了抽取过程中可能遇到的系统故障和网络故障问题,具有较高的健壮性。Abstract: In the background of coal mine, this paper analyzed, designed and implemented a kind of data extraction program triggered by data sources, with DTS tool and.NET remote architecture. The program can load data sources distributd in different places to data warehouse, and considered system failure and network failure during extracting data. It has higher robustness.
