【摘要】 传统的数据仓库只能分析历史数据且数据抽取周期过长,极大地降低了企业的应变能力。实时数据仓库的出现改变了这个局面。以此为基础的基于多Agent系统的四层数据仓库体系结构(MART-DW),一方面提高了数据仓库的主动性和实时性,另一方面也增强了系统的伸缩性,能够更加有效地管理分布式集成环境。更多还原

【Abstract】 The traditional data warehouse can only analyze historical data and the cycle of ETL is so long that enterprise’s capability of meeting an emergency is reduced greatly.
