Parallel RPE Query in XML Database System
XML数据库的并行RPE查询

Existing query methods on XML documents arc usually designed for centralized environments. As the amount of documents in Web applications is increasing very quickly t the existing query methods can not meet the needs of new Web applications. By extending the query processing strategy for centralized environments, we design and implement a parallel query processing method based on RPE. The experimental results show that the method has good speedup and scaleup performance in the case of heavy workload.
