------------------------------------

There are a few ways - many users already use them like that:
- Pages(Click or not) access only the Services and Entities (maybe helpers too)
- not the DAO (in fact there's no need for it most of the time).
- Services expose only interfaces to the Pages
- Services have the implementation for the desired back-end (so the DAO is
usually merged here too - like the click-examples)
- Entities may also expose only interfaces (this would have the advantage of
being able to easier interchange Cayenne, OODBs or whatever backend)
For Cayenne, there are Datamaps, so basically each "standalone" unit should
have it's one Datamap. I was told that this should work
with Cayenne, only it's not yet supported in the Modeler (and a cayenne.xml is
still needed yet - but there's a JIRA item for this).
(What I haven't understood yet is how the automatic but optional reversed
relationships across Datamaps should work)
For OODBs there's no problem: the separation is done using different Java
packages per module.
Well, I'm just a newbie, but at least this is how I understood from a (Click)
JUG presentation that modularity should work.
