Title: PDT-Based Document Fragmentation of XML Streaming Data
Abstract: Unlike in conventional databases,queries on XML stream data are bounded by not only the memory capacity but also the real time processing.Based on the Hole-Filler model,a path frequency tree(PFT) is defined according to the statistic information on queries about XML to set out a sibling-based document fragmentation policy including corresponding algorithm.Then,an alternative membership-based document fragmentation policy and corresponding algorithm are proposed.Both algorithms can effectively enhance the utilization and cohesion of XML fragments.Testing results showed that the PFT-based document fragmentation algorithms perform well on query cost and other properties.
