Functional overview

With the graphical interface and the Browser tree view of PowerDesigner XML Model, you can design an XML diagram which represents the content of an XML Schema Definition file (.XSD), a Document Type Definition file (.DTD) or an XML-Data Reduced file (.XDR). Since XML structures can be very complex, it is much easier to visualize them through comprehensive and explicit diagrams, than to read XML-coded pages.

Once you have created an XML diagram, you can generate an XSD, a DTD or an XDR file to share the structure of an XML document via an ordinary plain text file.

Conversely, you will be able to reverse engineer an XSD, a DTD or an XDR file into an XML model, with its corresponding diagram.

The XML Model allows you to:

♦Build an XML model

♦Check an XML model

♦Map objects in an XML model

♦Edit a report of an XML model

♦Generate and reverse engineer an XSD, a DTD or an XDR file

♦Generate an XML model from a Physical Data Model (PDM)

♦Generate an XML model from an Object Oriented Model (OOM)

♦Generate an XML model from an XML model
