Top down reference for Rails?

I appreciate the blend of demo development with top down perspective
– big picture view – of the Agile Rails book. Is there a reference
that focuses on the big picture view with less demo? None of the
Rails books I’ve checked on Amazon seem to offer this. Perhaps there
is an online reference I don’t know about? TIA.

explanatory on the architecture?
