This paper studies the SOA and data warehouse technology and analyses the real-time data requirement of the data warehouse. Then this paper discusses the real-time data modeling, acquisition and analysis, and analyses and designs the real-time data warehouse architecture. In this architecture, the introduction of a multi-level real-time data cache facilitates the real-time data storage. And the using of the Web services to capture rean-time data makes the real-time data capture and load easily. This paper also discusses the real-time data analyse in the SOA based real-time data warehouse. Finally, this paper designs the electric power real-time data warehouse for the electricity analyse. |
