基于分布式数据仓库动态增量视图维护的研究

Study on the maintenance of dynamic increment view based on distributed data warehouse

分布式数据仓库分为局部/全局数据仓库、技术分布式数据仓库和独立演进的分布式数据仓库三种类型。分析了视图脱机维护和联机维护存在的不足,根据三种类型分布式数据仓库给出了动态增量视图维护的模型及方法。

Distributed data warehouse can be classified as local/global distributed data warehouse, technology distributed data warehouse and independent evolution distributed data warehouse. This paper analyzes existing problems of view off - line maintenance an on - line maintenance, according to the three types of distributed data warehouse, we give the model and method of dynamic increment view.
