XML with Databases

• Modeling Databases in XML
Data is king! This statement is often made by IT professionals because a
large percent-age of their applications are data driven. With the emergence of
XML as a technique for describing data, the frequently asked question is, “How
can we integrate XML with our existing relational database?” In particular,
developers need a solution to dynamically generate XML documents using
information stored in databases.
XML and database integration is important because XML provides a
standard technique to describe data. By leveraging XML, a company can convert
its existing corporate data into a format that is consumable by its trading
partners. XML allows the development team to define a set of custom tags
specific to its industry. A trading partner can import the XML data into its
system using the given format. The trading partner also has the option of
converting the data to a different XML format using XSLT. XSLT is covered in
Chapter 9, “Transforming XML with XSL.”
