Effective pruning for XML structural match queries
Extensible Markup Language (XML) is becoming the de facto standard for exchanging information over the Internet, which results in the proliferation of XML documents. This has led to increased interest in this area by the research community. One of the main challenges is processing large collections of XML documents efficiently. Most current methods suffer from two drawbacks: an inability to complement each other to further enhance query processing performance without modifying the existing query processing engine; and an incapability of being customized for different structural and usage characteristics. This paper presents a new approach for structural query processing called Property-Driven Pruning Algorithm (PDPA), which offers the twin features of structural query processing independence and plug-and-play properties to overcome both drawbacks. PDPA consists of two phases: the offline and the online phase. During the offline phase, a list of pruning properties is added into the ori...
