The figure shows a database with the emp table, which has the following columns: Empno, Ename, Job. This is the visual model in which data is stored in tables. This visual model is translated to an XML document XML view as follows:
<oracle>
 <scott>
  <emp>
   <row>
    <EmpNo> 21
    <Ename> John
   </row>
  </emp>
 </scott>
</oracle>
Next the XML visualization is shown as a URL:
/oracle/scott/emp/row/empno=21/ename...
