摘要
数据仓库中用存储大量的物化视图来加速OLAP的查询响应,物化视图的选取是数据仓库设计中的一个重要问题。论文提出了一个有效的物化视图选取算法,采用基于数据立方体层次搜索的方式选取视图。经分析与测试表明,该算法取得良好的效果和效率。
A data warehouse stores large amounts of materialized views to accelerate OLAP queries. The selection of materialized view is an important decision in designing data warehouse. The paper presents an efficient algorithm for materialized views selection based on searching view in the layer of data cube. The analysis and experimental study show that the algorithm has better solution and high efficiency.
