Observations of MongoDB and CouchDB

Interesting article from the folks at Ocasta Labs. Ocasta Labs has been using CouchDB for over a year now. Recently a project popped up where they mention in their post that CouchDB did not seem like the right fit. The primary reason:

It turns out the reason it was the right choice was that Mongo is quite traditional. It relies on you having a middle tier where your app logic resides. Couch is more radical and it not only replaces the traditional database but also the middle tier. If, as we did on this particular project, you already have a middle tier then using Couch adds complexity to the solution.

Other interesting points from the article:

• A pure Couch application is simpler to deploy, upgrade and scale
• Struggled with Mongo when using map/reduce
• Couch you can write and test the map without the reduce which helps, no similar mechanism available in MongoDB
