In this paper we consider the problem of XML data which may be inconsistent with respect to a set of functional dependencies. We propose a technique for computing repairs (minimal sets of update operations making data consistent) and consistent answers. More specifically, our repairs are based on i) the replacing of values associated with attributes and elements, and ii) the introduction of a function stating if the node information is reliable. © Springer-Verlag Berlin Heidelberg 2003.

Abstract
In this paper we consider the problem of XML data which may be inconsistent with respect to a set of functional dependencies. We propose a technique for computing repairs (minimal sets of update operations making data consistent) and consistent answers. More specifically, our repairs are based on i) the replacing of values associated with attributes and elements, and ii) the introduction of a function stating if the node information is reliable. © Springer-Verlag Berlin Heidelberg 2003.File in questo prodotto:
