一种云计算环境下的XML查询数据服务的优化方法
An optimization method for XML query data service in cloud environment
摘要
Abstract
Providing XML data service in could environment attracts more and more attentions.By introducing existed XQuery engine (such as saxon) into cloud environment,a XML data query service framework was implemented.To improve the efficiency of XML data query in cloud environment,an optimization method based of XPath projection is applied in the procedure of splitting XML data,only leaving the data related to XQuery statements.Experiments show that the optimization method effectively reduces both the data size and the query processing time of XML data service.关键词
