Derby's roots in Cloudscape focused on the embedded database market - 
typically some form of database that could be distributed with an 
application rather than as a standalone RDBMS. This is kind of like 
HSQLDB but in comparison Derby has many more capabilities (e.g. 
multi-user isolation, reliably durable data, distributed transactions, 
...) A lot of organizations have used MySQL in similar circumstances and 
Derby may well provide an alternative there.

Another area is that of a simple but reliable data store for a web 
application, perhaps in conjunction with a Java server such as Apache 
Tomcat or Apache Geronimo; there have been a lot of installations of 
HSQLDB and MySQL in those environments and if that is your situation 
Derby may again be a good alternative.

Derby is also aimed at the mobile arena - for example, Dan's work on 
JSR169 support.

On the other hand, I wouldn't recommend it for a 10TB datamart - well 
not yet anyway :-)

In the end, it really depends on what you want to use it for.
