Analysis and Comparison on Maintenance Algorithms of Materialized View in Data Warehouse

Zhu Wen

Abstract

With updating of data sources, the materialized views in data warehouse must be maintained in time. But how to freshen the materialized views effectively is a very complex and difficult task, and it is one of the key issues in the date warehouse. Concernes much on this problem, and make a detailed analysis and comparison on materialized view maintenance algorithm, gives a systemic conclusion about the current research state and indicate the future research domain.
