Apache CouchDB, commonly referred to as CouchDB, is an open source document-oriented database written mostly in the Erlang programming language. It is part of the NoSQL group of data stores and is designed for local replication and to scale horizontally across a wide range of devices. CouchDB is supported by commercial enterprises Couchbase and Cloudant.
CouchDB is a document oriented database that can be queried and indexed using JavaScript in a MapReduce fashion. CouchDB also offers incremental replication with bi-directional conflict detection and resolution.
Couchbase is the leading provider of NoSQL database technology, powering some of the world’s largest web applications. Whether a corporate e-commerce system, a blockbuster social game or the world’s largest online advertising system, Couchbase offers a more flexible, scalable and cost-effective approach to data management than traditional database solutions.
