Assuming that the data is not part of a document and is really not  
suited to QSettings,I suggest that you have a simple XML file that is  
loaded on program start and written on program exit.

But first, I would consider using QSettings, because keeping multiple  
support and configuration files can turn into a head-ache.

The QSql module is actually pretty lean compared t other XML  
implementations.  Once you get used to it, it's a very effective way  
of doing this sort of thing.
