Health Visiting in Anxious Timesing. It provides a natural framework for consistency and safety questions, which first considers approximate solutions and then exact solutions obtained with a Corrector..We consider a model based on transducers of words and trees, and study .-Consistency, i.e., the problem of deciding whether a giv

Helene Bang Appel,Rashmi Singlaal, and the axiomatisation proposed for XML keys is incomplete even if key paths are simple. Therefore, the axiomatisation and also the implication problem for XML keys are still unsolved..We propose a set of inference rules that is indeed sound and complete for the implication of XML keys with simp

XFDs are more complicated than relational functional dependencies because the set of XFDs satisfied by an XML document depends not only on the document values, but also the tree structure and corresponding DTD. In particular, constraints imposed by DTDs may a

We consider conjunctive properties over these random graphs, and investigate the problem of computing their asymptotic conditional probabilities. This provides us a novel approach to dealing with uncertainty in databases, with applicati
