Formal semantics for XQuery with side-effects have been proposed in [13,16]. We propose a different semantics which is better suited for database compilation.

Abstract
Formal semantics for XQuery with side-effects have been proposed in [13,16]. We propose a different semantics which is better suited for database compilation. We substantiate this claim by formalizing the compilation of XQuery extended with updates into a database algebra. We prove the correctness of the proposed compilation by mapping both the source language and the algebra to a common core language with list comprehensions and extensible tuples. © Springer-Verlag Berlin Heidelberg 2007.File in questo prodotto:
