Maybe I just worded it poorly. How about "I'm trying to understand how  
couchdb would solve some problems that I'm currently solving with SQL  
and come up with some intermediately mappaable vocabulary so that I  
can gloss over the bits that I don't understand until I do so that I  
can tackle one concept at a time". But that's much longer :)

Ah, very cool. I was mis-understanding the Key, which answers almost  
all of my questions as once

That answers my next question too.

Oh I will :)

I'm an Erlang developer. Any tips on where to start reading if I plan  
to begin understand the code-base?
