I do struggle with the difference between:
chunk … chunk
and
chunk … relationship … chunk.
where … is a transition.
I used to think that the tuple is a basic unit but this proximity question keeps haunting me.
Does simple proximity count as a relationship?
Am I looking at this wrong; should I see the tuple as two separate things?
chunk … relationship
and
relationship … chunk
Another possibility is proximity in the WHAT stream vs relationship in the WHERE stream.
