| Research Abstract |
This research aims to propose a framework for XML schema update and XML document transformation considering information preservation. Wefocused on query preservation, which is a formalization of information preservation. We showed that, for some transformation and query classes modeled by tree transducers and tree automata, the problem of deciding the query preservation is decidable and a query that works directly over the transformed data can be constructed.
