Yep, definitively an option!

Our iterative process is something like:

export data -> change dia -> dia2code -> ddl -> recreate db ->
recreate dbic model -> load data

So basically we can change the DB quiet frequently and we have a
detailed change log on the schema so it's realtive easy to re-create
and populate a fresh new db every time we iterate a new version.

The advantage of this approach (to us) is that the UML class diagram
is always the latest DB model and the result source classes are
disposable, that's why we want to keep the custom model code separate
from the auto-generated classes.

Thanks!
