Sean and Sam would have to answer as to the original considerations but 
having tuples as a basic data model does enable the handle system to 
leverage most existing storage solutions, and vice versa, the handle 
system can be used as a storage mechanism for various data storage needs.
That said, although I agree that theoretically the handle system could 
be made to provide RDBMS functionality, I'd hate to see the performance 
of a join :)! 

On the same thought thread, there has been a steady (but not growing...) 
interest in using the handle system to store RDF graphs.
The main advantage being the truly distributed administration and 
organic growth of such a graph. 
Storing the tuples would be easy, but the problem occurs if you need to 
search those RDF graphs.
We are rummaging around for ways to provide a search interface service 
to search specifically configured handle servers.
