摘要

数据仓库存储大量物化视图，以提供有效的决策支持或OLAP查询。视图选择问题解决了在存储空间限制下选择最合适的物化视图集的问题，是数据仓库研究中的一个难题。本文提出了一种选择物化视图的遗传算法。我们也用实验来证明我们的方法的力量。

Materialized view selection using genetic algorithms in a data warehouse system

A data warehouse stores lots of materialized views to provide efficient decision-support or OLAP queries. The view-selection problem addresses the selection of a fittest set of materialized views under the limitation of storage space forms a challenge in data warehouse research. In this paper, we present genetic algorithms to choose materialized views. We also use experiments to demonstrate the power of our approach.
