| Abstract: | Materialized view selection is an important problem researched in a data warehouse,which influences the efficiency and maintenance cost of data warehouse.In this paper,we give the cost model of materialized view selection in the AND-OR View Graph.We present materialized view selection algorithm and strategy using the genetic algorithm aswell.The experimental studies indicate that the genetic algorithm has better solutions and high efficiency. |
