Selection of Materialized View in Data Warehouse

Zuping Zhang

Abstract

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.
