Okay. And issue "add/modify/whatever column" type of commands to the users derby database?

Exactly. Problem is that Derby is a bit annoying in that you can't alter columns in very many ways. Can't even make a non-null field into one allowing nulls. So updates take the form of:

- create new column
- copy data
- delete old column

Of course all this runs before Cayenne gets initialised.
