Advanced Data Stream Sharing 
Abstract:
Using multi-query optimization for sharing common work among multiple queries requires the identification of shareable query components. This kind of optimization is particularly effective in distributed data stream management systems (DSMSs) with multiple continuous queries running concurrently over long periods of time. In this paper, we introduce an abstract property tree (APT) and its extension, an abstract property forest (APF), for representing, matching, and merging XQuery-based queries a...    »
