Fourth International Conference on Web Information Systems Engineering (WISE'03) Quantifiers in XQuery Roma, Italy December 10-December 12 ISBN: 0-7695-1999-7
We present algebraic equivalences that allow to unnest nested algebraic expressions containing quantifiers for order-preserving algebraic operators. We illustrate how these equivalences can be applied successfully to unnest nested queries formulated in XQuery. Measurements illustrate the performance gains possible by unnesting.
