As the popularity of XML keeps growing rapidly, XML compliant structured document management becomes an interesting and compelling research area. Query optimization for structured...
The increasing volume of data stored as XML documents makes fragmentation techniques an alternative to the performance issues in query processing. Fragmented databases are feasible...

We study XML stream-specific schema-based optimization. We assume a widely-adopted automata-based execution model for XQuery evaluation. Criteria are established regarding what s...
Several requirements for algebra suitable for ecient cost-based optimization are presented. It is shown that known XML algebras do not fully satisfy this requirements. A new alge...
