摘要
在数字化校园建设中将既有业务系统的数据整合形成数据中心,并在此基础上进行数据分析,形成决策支撑系统,为相关管理部门提供服务.数据分析中ETL(数据抽取、转换与加载)是非常关键的技术.本文就ETL的分析和设计进行了一些基本的研究和探讨.
The key point of constructing digital campus is open data center established on the base of managing and combining the past data of all application systems. It will serve for the management of campus to form supporting system of decision-making by data analysis. ETL (extraction, transformation, loading) is the most important technique among the data analysis. We carry out the essential discussion on the analysis and design of ETL.
