View Update Translation for XML

Free registration required

Executive Summary

The authors study the problem of update translation for views on XML documents. More precisely, given an XML view definition and a user defined view update program, find a source update program that translates the view update without side effects on the view. Additionally, they require the translation to be defined on all possible source documents; this corresponds to Hegner's notion of uniform translation. The existence of such translation would allow to update XML views without the need of materialization. The class of views they consider can remove parts of the document and rename nodes.
