并行技术在数据仓库中的应用

Application of Parallel Technology in Data Warehouse

由于庞大的细节数据的存储 ,使得数据仓库向TB级发展 ,加之许多复杂处理 ,所以使并行技术的实现成为必然。在分析了并行技术的基础上 ,认为采用基于无共享结构的MPP体系结构最适合于数据仓库的现状和发展趋势 ,并指出了利用并行技术设计大型数据仓库应注意的问题。

Since a great amount of details data needs to be stored and the development of data warehouse tends to TB grade,such as multicomplexity processing,it is a necessity to implement parallel technology.After analyzing the parallel technology,it is suggested that MPP structure system based on nonshared structure is an optimal candidate for present and developing tendency of data warehouse;and the problems in designing the large data warehouse with parallel technology are also pointed out.
