摘要
基于AND-OR ViewGraph,应用视图选择的代价模型,提出了利用遗传算法实现实视图选择的方法和策略,实验结果证明这种算法结果更优效率更高.
In this paper, the cost model of materialized view selection in the AND - OR View Graph are given. And presents materialized view selection algorithm and strategy using the genetic algorithm. The experimental results indicated that the genetic algorithm has better solutions and high efficiency.
