摘　　要： A Data Warehouse System has a more large scale of data, and rather simple process logic than a DBMS. Sothose optimize means of DBMS Query system are not so valid. This paper discusses the optimize policy used in to par-allel DW system ParaWare, such as query division, public sub query mergence, and fill in the query result. It alsogives out the right algorithm. A Data Warehouse System has a more large scale of data, and rather simple process logic than a DBMS.
