|Issue Date:||2006||Citation:||Lee, Q.,Bressan, S.,Rahayu, W. (2006). XShreX: Maintaining integrity constraints in the mapping of xml schema to relational. Proceedings - International Workshop on Database and Expert Systems Applications, DEXA : 492-496. ScholarBank@NUS Repository.||Abstract:||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. 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.
