Experimental results indicate the efficiency and feasibility of DCO, and also show that DCO can overcome the SPSE (space-performance saturation effect) of materialized views in some degree.

• 实验结果在表明算法有效、可行的同时；也显示出该算法可以在一定程度上克服静态物化集存在的空间-性能饱和效应(space-performancesaturationeffect；简称SPSE)；使通过增加物化空间进一步提高数据仓库对查询的响应速度成为可能.
