James,
You seem to be confusing Entities and fetch specs with tables and views.
While you can link multiple entities to the same table for performance
reasons I'd try to avoid it as it can lead to problems. If you find out
that you need to do something like this for performance reasons (and I'd
only do so after evidence that performance was a problem) then "raw row"
fetches are a more appropriate solution.
In your case I'd model two entities, Portfolio and Project. I'm not clear
on what you intend by "portal", perhaps that is another entity.
You will have much more success with WO if you stop thinking about tables
and fields and just think about objects. Chances are there will be no
performance problems and you are worrying needlessly. You might also want
to reconsider the design of the project table. Is it fully normalized?
Chuck
