Abstract :
An effective method to reduce the time of response time about query is to materialize views in data warehouse. Current strategies mainly consider the methods of the primary selection of materialized views. Due to the insufficient consideration of the dynamic refreshment, we address a new dynamic method which can wash out materialized views and add new materialized views in the set of current materialized views on the basis of the greedy algorithm.
