摘要：
The XML is becoming the new standard for the integration and exchange of data over the Web. Materialized views have been found to be very effective at speeding up queries in the XML information integration system. In this paper, we present a novel technique for discovering and generating materialized XML views in data integration system. First we propose a new method about discovering frequent query patterns by constructing the global XML query plan. Then we propose a heuristic approximate algorithm to generate the materialized XML views based on the global query plan in the information integration system. The experimental results generated from the real data validate the thesis of this paper and reveal that the algorithms work well in practice.
