Apache CouchDB, commonly referred to as CouchDB, is an open source database that focuses on ease of use and on being "a database that completely embraces the web". It is a NoSQL database that uses JSON to store data, JavaScript as its query language using MapReduce and HTTP for an API. One of its distinguishing features is easy replication.

Apache CouchDB, commonly referred to as CouchDB, is an open source database that focuses on ease of use and on being "a database that completely embraces the web". It is a NoSQL database that uses JSON to store data, JavaScript as its query language using MapReduce and HTTP for an API. One of its distinguishing features is easy replication.

Unlike in a relational database, CouchDB does not store data and relationships in tables. Instead, each database is a collection of independent documents. Each document maintains its own data and self-contained schema. An application may access multiple databases, such as one stored on a user's mobile phone and another on a server. Document metadata contains revision information, making it possible to merge any differences that may have occurred while the databases were disconnected.

CouchDB implements a form of Multi-Version Concurrency Control (MVCC) in order to avoid the need to lock the database file during writes. Conflicts are left to the application to resolve. Resolving a conflict generally involves first merging data into one of the documents, then deleting the stale one.

Other features are ACID semantics with eventual consistency, MapReduce, incremental replication and fault-tolerance. Administration is supported with a built-in web application called Futon.
