    3. COThe currently accepted answer of Prabhat is a WTF. Renaming the extension of a valid log4j.xml file to a wrong one? Did it *really* solve your concrete problem? The answerer clearly has no idea that it's also possible to configure log4j by XML instead of by Properties.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
