A couple weeks ago I wrote about NoSQL and provided a short overview of the landscape of non-relational databases. One that has become increasingly popular is Apache CouchDB, so I’d like to spend a couple weeks digging into it a bit and talking about why it’s so interesting. Before I do, it’s worth noting that Ubuntu 9.10 was just released and uses CouchDB under the hood.

"The CouchDB development team is proud to announce CouchDB version 0.7.0 is now available at http://code.google.com/p/couchdb/downloads/list ..."

Relational databases define a strict structure and provide a rigid way to maintain data for a software application. Apache's open source CouchDB offers a new method of storing data, in what is referred to as a schema-free document-oriented database model.

Apache CouchDB is a document-oriented database that can be queried and indexed in a MapReduce fashion using JavaScript. CouchDB also offers incremental replication with bi-directional conflict detection and resolution.

Canonical made it clear from the get-go that Ubuntu 9.10 was going to pack plenty of cloud functionality for both desktops and servers. One piece of that puzzle is CouchDB, which developer Elliot Murphy was overjoyed to announce has slipped in under the wire to beat the Karmic code freeze.

The open source Apache CouchDB database project hit a major milestone this week with the release of version 0.11. The release is an important one for the NoSQL database variant as it matures toward its 1.0 release.

According to its motto, the underlying premise behind the open source CouchDB NoSQL database is about helping developers "relax" -- chiefly by providing them with a simple, powerful database alternative.
