The Query Optimization of Parallel Data Warehouse System ParaWare
并行数据仓库Para Ware系统的查询优化

A Data Warehouse System has a more large scale of data, and rather simple process logic than a DBMS. So those optimize means of DBMS Query system are not so valid. This paper discusses the optimize policy used in to parallel DW system Para Ware, such as query division, public sub query mergence, and fill in the query result. It also gives out the right algorithm.
