Querying Streaming XML Data Using Hash-Lookup Query Trees

By et al. James Cheng

Abstract

The rapid growth in the amount of XML data and the development of publish-subscribe systems have led to great interest in processing streaming XML data. While a number of efficient systems have been developed to process XPath filters on XML streams, the performance of existing systems that query streaming XML data is inadequate. We propose the QstreamX system for querying streaming XML data using a novel structure, called Hash-Lookup Query Trees, which consists of a Hashtable, a Static Query Tree (SQT

Topics: and a Dynamic Query Tree (DQT). The Hashtable is used
