A Domain Integrity Constraint Control for XML Documents Alexandre Tagliari Lazzaretti and Ronaldo dos Santos Mello   View Paper (PDF)   Return to XML Abstract Integrity constraints for XML documents are mainly defined through XML schemas: DTD and XML Schema. However, XML schemas do not have support for all existing kinds of domain integrity constraints in SQL databases. This paper resents a control called XDC that aims at supporting domain integrity constraints that cannot be handled by XML schemas. It is composed by an XML language for domain integrity constraint specification, called XDCL, and an XDCL parser that validates such constraints. XDCL allows specifying conditions and executing actions, as in SQL databases. XDC is an independent mechanism that can be used by users, applications or XML databases to validate domain integrity constraints. ©2006 Association for Computing Machinery
