Updating in XML Using Semantic Constraints

Free registration required

Executive Summary

A novel technique for updating in XML using semantic constraints is proposed. In the proposed technique for XML updating, the authors consider close value pair semantics in ordered XML documents. Further, how semantic constraints can be incorporated with integrity constraints for XML updating and how to update XML views using semantic constraints are discussed. Updating is an important operation in traditional database management systems. In recent years, XML is widely used in many database-centric applications such as data exchange and data integration. In database-centric approach of XML has necessitated the update operations in XML in recent past. Most update operations in XML are based on un-ordered semantics of XML data.
