CouchDB, like Redis, Cassandra, and MongoDB, is a “NoSQL” database. Similar to other databases of its kind, CouchDB stores its information in a non-relational database, keeping its data in separate JSON documents. The advantage of this approach is that no particular schema is required for the inputted information, making the data contained within the documents more similar to their actual real world counterparts.
The couchdb database also has a web interface, called Futon.
