Good point - this needs clarification. The idea of zero admin with 
Derby is that an application doesn't need maintenance once it's 
deployed. It doesn't mean that no tuning is required - just that it's 
not required once the app is in use. This is an important aspect of 
an embeddable database, since the end user may not even know there's 
a copy of Derby in the app.

So, for example, if the developer sets up indexes to ensure adequate 
performance, the end user will not have to do periodic maintenance on 
the indexes to keep the same level of performance.
