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。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. The emergence of real-time data warehouse changes this situation. A 4-tier data warehouse architecture based on multi-agent system improves the active and real-time performance of data warehouse. On the other hand, the flexibility of the system is enhanced in this architecture, which makes the distributed environment be managed more efficiently.
