基于分布式系统概念的分布式数据仓库

A Distributed Data Warehouse Based on the Concepts of Distributed System

以分布式系统的概念,描述了以主题分布为特点的分布式数据仓库,建立了节点主题处理原则,论述了此种分布式数据仓库的特点,并与Inmon先生描述的分布式数据仓库进行了特征比较。此外,还简要地分析了节点仓库与数据集市的异同,构建分布式数据仓库的方法与费用,从而指出分布式数据仓库应用的乐观前景。

Based on the concepts of distributed system, the distributed data warehouse with the character of subject-distributed is described and the concept of processing subject in the node warehouse which the subject is in(CPSN)is established in this paper. The characters of this distributed data warehouse are compared with Mr. Inmon' s. This paper also briefly analyses the similarities and differences between the node warehouse and dada mart. It shows a good prospect in application of the distributed data warehouse to explain the method and cost on building the distributed data warehouse.
