Since I saw the presentation about Couch Potato, a library for using CouchDB with your Ruby applications I was very curious about how to map a relational schema (that is the most common way to model entities and their relationship) in a document / plain schema where each element has no relation with the others.
And at last, today I found a cool post from Google and it's equivalent for CouchDB.
Now it's time to play with CouchDB!

While the 'one-to-many' approach looks straightforward, the 'many-to-many' implementation looks more like a hack... I don't think it's going to scale well (they even state that: "CouchDB only allows you tou do things that scale well") but then if your data model is heavy on the relational side, why use a document DB in the first place?
Interesting stuff.

I agree with you. In fact, in the CouchDB page you can read:
What it is Not:
* A relational database.
* A replacement for relational databases.
* An object-oriented database. Or more specifically, meant to function as a seamless persistence layer for an OO programming language.
But there are son many scenarios in wich it can be very useful.
In fact, I think it would be very esasy to combine AR models with CouchDB models, thanks to gems like Couch Potato (http://github.com/langalex/couch_potato/tree/master)
