RavenDB vs MongoDB: Which is Better? This White Paper compares the two leading NoSQL Document Databases on 9 features to find out which is the best solution for your next project.
CouchDB is used to power the Ubuntu One service, which can store and synchronize data. Mozilla is currently experimenting with CouchDB in their Raindrop project and Sauce Labs is using it for all of their database needs. Now that CouchDB 0.11 is out of beta, we'll see if more organizations are willing to try implementing the data store's unique features.
The latest release has fixed several bugs and now offers support for building windows installers, "raw" binary collation, and replication enhancements. Here is the list of changes:

- Improved view index build time by reducing ICU collation callouts.
- Added option to implicitly create replication target databases.
- Improved view information objects.
- Provide Content-MD5 header support for attachments.
- Improved the statistics calculations to use an online moving windowalgorithm.

CouchDB is already beginning to enable new distributed types of applications and data. NoSQL blogger Eric Florenzano predicts that CouchDB will one day become relevant to anyone who owns a computer: "I imagine that some day every computer will come with CouchDB pre-installed and it'll be a data store that we use without even knowing that we're using it."
