基于数据仓库的并行星型联结策略

Parallel Star Join Strategy On Data Warehouses

在本文中,我们探讨一种基于并行处理技术并且能够改进数据仓库查询方法。而且,我们设计运算法则对于任务和数据进行分割来实现并行星型联结。

In this paper,we are interested in developing strategies for improving query processing in data warehouses by exploring the applicability of parallel processing techniques.And,we propose a strategy which incorporates both task and data partitioning and present the Parallel Star Join Algorithm.
