Apache CouchDB is an open-source distributed document-oriented NoSQL database governed by the Apache Software Foundation. It uses JSON for data storage, a RESTful HTTP/JSON API for all database operations, and the Couch Replication Protocol for multi-primary synchronization across servers, mobile devices, and browsers. CouchDB supports Mango queries, MapReduce views, and offline-first application architectures.
