Body
I'll lead off with the start of the description from the <a href="http://download.oracle.com/javase/6/docs/api/javax/activation/DataHandler.html" rel="noreferrer">API entry for <code>DataHandler</code></a>: <blockquote> The DataHandler class provides a consistent interface to data available in many different sources and formats. It manages simple stream to string conversions and related operations using DataContentHandlers. </blockquote> Admittedly, that's not the clearest description. <code>DataHandler</code> has to do with XML and SOAP, which you can see from the <a href="http://download.oracle.com/javase/6/docs/api/javax/activation/class-use/DataHandler.html" rel="noreferrer">the use tab of its API page</a>. Like you, I've used it to represent data about an uploaded file as it's being sent from one web service component to another for processing. The <code>Transferable</code> interface that <code>DataHandler</code> implements is not exactly referring to "transfer" of the kind serialization deals with. It's about transfer of information between separate components in a program, or separate programs, not saving an object for later use. See the <a href="http://download.oracle.com/javase/6/docs/api/java/awt/datatransfer/Transferable.html" rel="noreferrer">API entry for <code>Transferable</code></a> for more. You'll notice that it links to <a href="http://download.oracle.com/javase/tutorial/uiswing/dnd/intro.html" rel="noreferrer">the Drag 'n' Drop Java Tutorial</a>, which has little to do with <code>DataHandler</code> but does illustrate a use of <code>Transferable</code>.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
