As XML becomes a serious candidate medium for the management and interchange of critical enterprise data, more attention to the issue of data integrity maintenance is needed. We propose a mapping of XML to relational that takes into account the integrity constraints expressed in XML Schema. We present a an extension, called XShreX, of the ShreX mapping. <p>We report the preliminary results of a comparative performance analysis using a mainstream commercial relational database management system. The results suggest that the extension of ShreX does not come at a prohibitive cost for insertions, deletions, updates and queries. In the case of queries, XShreX can even yield a performance improvement.</p>
