Yes it that. The data model is created with a custom Java class which have
getModel method.
You select a ftl template, right click to open contextual menu and start
the debug. When you do that
it creates a Freemarker Template instance and link it to dbgp debugger
service instance.

But I agree with you, the general use is to debug an application. In this
case the system properties must be used.
I have not managed this case, but I have intention to do that. See

Get your SQL database under version control now!
Version control is standard for application code, but databases havent 
caught up. So what steps can you take to put your SQL databases under 
version control? Why should you start doing it? Read more to find out.
