A New Cache Model for XML Based on Frequency Path Tree

This paper proposes a novel XML cache model based on Frequency Path Tree,which is named FTree Cache.Based on Frequent path pattern,new model projects the XML document to a new XML document.The new document is used as a cache to improve the efficiency of queries.The experiments show that the method reduces memory requirements and significantly improves the queries response time.The memory is reduced to 20% and time is reduced to 43%.
