Title: Consistent answers from integrated XML data
Author(s): Tan, Zijing; Liu, Chengfei; Wang, Wei; Shi, Baile
Abstract: We consider the problem of using query transformation to compute consistent answers when queries are posed to virtual XML data integration systems, which are specified following the local-as-view approach. This is achieved in two steps. First the given query is transformed to a new query with global constraints considered, then the new query is rewritten to queries on the underlying data sources by reversing rules in view definitions. The XPath query on the global system can be transformed in XQuery. We implement prototypes of our method, and evaluate our framework and algorithms in the experiment.
