Abstract: This paper proposes three new XML integrity constraint techniques in CoXML system: Translation of functional dependencies in data exchange based on XML; XML schema oriented key constraints translation; validating key constraints over XML document using XPath. The experimental results conducted on CoXML reveal that these techniques work well in practice.
