摘　　要：Materialized views can be used to improve the performance of queries. When there are large amounts ofviews, it will take much time to sequentially search views that possibly answer queries. A level index is presented topartition views into much smaller subsets and can be used to separate those candidate views fast.Materialized views can be used to improve the performance of queries.
