Efficient Evaluation of Multiple Queries on Streamed XML Fragments
[chapter]
2006
Lecture Notes in Computer Science
Preserved Fulltext
With the prevalence of Web applications, expediting multiple queries over streaming XML has become a core challenge due to one-pass processing and limited resources. ...
Recently proposed Hole-Filler model is low consuming for XML fragments transmission and evaluation, however existing work addressed the multiple query problem over XML tuple streams instead of XML fragment ...
In this paper, we present an efficient framework and a set of techniques for processing multiple XPath queries over streamed XML fragments. ...
