Yep, both of those are good.

One key thing to remember/know is that MapReduce in CouchDB is building an *index* for you to *query* with query string parameters (startkey/endkey, keys, etc) when you request the View (aka Index):

That's likely an oversimplification, but it helped me. :)

The "view cookbook for sql jockeys" in the o'reilly definitive guide is
good as well.

Hi all,

coming from SQL I still have problems in getting a firm understanding on how to use map/reduce functions properly. Are there any good tutorials out
there to help?

Thanks,
Stephan
