INTEGRATE REWRITING AND DATA PARALLELISM FOR XQUERY OPTIMIZATION
摘要
Abstract
Xquery optimization is the key approach to improve the performance of Xquery engine. According to the language features of Xquery and the requirement of query in multi data sources, high effective query plans generated through rewriting in Xquery. To adapt to multi-core condition, data parallelism implemented by utilizing parallelized primitives in intermediate language. Query engine prototype developed and cases experiments show the optimization can effectively improve query performance.关键词
