XML store

XML (Extensible Markup Language), defined by W3C (The World Wide Web Consortium), is the universal format for exchanging  data between applications on the Web. XML does not replace HTML which is HyperText Markup Language for webpage User Interface design.

DTD (Document Type Definition) defines the structure of an XML document and XSD (XML schema definition) describes the structure of an XML document. DTD and XSD define tags and inclusion relationship between them, the order of tags, the number of tags cab be included, and tag attributes and its values.

XML specification verifies document by XML structure information such as DTD/XSD at XML analysis step, so the application using XML data can be free from data validation. The application using XML data takes advantage of easy data exchange with other applications.

OZ Report provides XML store for XML based data source.  XML store supports XML document with DTD/XSD while FILE/HTTP store supports XML document without DTD/XSD. XML store can have two forms, i.e., XML DTD store and XML XSD store.
