  View update is the problem of translating an update to a view to some updates
to the source data of the view. In this paper, we show the factors determining
XML view update translation, propose a translation procedure, and propose
translated updates to the source document for different types of views. We
further show that the translated updates are precise. The proposed solution
makes it possible for users who do not have access privileges to the source
data to update the source data via a view.
