Well, technically Berkeley DB has nothing to do with SQL!

You can implement an SQL query language/interpreter which would unfortunately 
defy the purpose of using Berkeley DB. As a matter of fact some SQL systems 
*are* implemented using Berkeley DB...

If you look at the design docs and example code, you will see how it is 
possible to make an interface to Berkeley DB that does not restrict the user 
in any way.... It is however only work in progress....

My intention is to bring it to such a state that you will be able to implement 
persistent data and GUI components in an easy way. Let's see how it comes 
out. Thanks for your comments.

Indeed the large part of the work is the design docs and sample codes that I 
haven't posted yet. I'm writing some sort of a generalized structure 
model/view framework that you can use to implement your own data widgets 
without being forced to use a table abstraction. Note that a table 
abstraction is only useful when you have SQL, which we do not have here. 
Neither we would want to.... Please follow the pointers I gave to berkeley DB 
documentation in the original post.

The work is going well, I hope to make a release in a couple of weeks and add 
this to kdenonbeta.

Sincerely,
