The eXtensible Markup Language (XML) is a key technology that facilitates both information exchange and e-business transactions. Starting with DB2 UDB Net. Data V1, an application can generate XML documents from SQL queries against DB2 or any ODBC compliant databases.Today DB2 UDB XML Extender not only serves as a repository for both XML documents and their Document Type Definitions (DTDs), but also provides data management functionalities such as data integrity, security, recoverability and manageability. User has the option to store the entire document as an XML user-defined column or to decompose the document into multiple tables and columns.Fast search via indices is provided for both XML elements and attributes. Section search can be done against the content of the document. Query syntax adheres to W3C standards such as Extensive Stylesheet Language Transformation (XSLT) and XML Path Language (XPath) specifications. User can retrieve the entire document or extract XML elements and attributes dynamically in an SQL query. In addition, XML Extender provides stored procedure to generate XML documents from existing data. Together with Net.Data, one can browse the content of the XML documents via the Internet.
