As part of coming to grips with CouchDB (and a particularly odious graph-theory problem) I've been looking around for design guidelines, hints and tips.

This MongoDB Schema Design document is quite helpful. The Link vs. Embed section clarifies the essential tradeoff here. In SQL world, link is the only tool …

As the #3 ranked contributor on http://programmers.stackexchange.com, I've provided my share of advice. 554 Answers to be factual about it. The moderators, however, have decided that I'm no longer welcome. It was simply shocking to be firmly (but politely) shown the door.

The issue was Python. Specifically …

I've started to work with couchdb.

I've blogged before about the problems of SQL schema in Escaping the Relational Schema Trap.

Looks like fun: Mid-Atlantic Developer Expo. June 27-29 2012 in Hampton, VA. Got a nice reminder through the 757 Labs mailing list. Community is a good thing.
