MongoDB is a widely used, general-purpose, document-oriented NoSQL database with features including high-availability replication and auto-sharding for horizontal scaling.

The MongoDB Community Edition database server and tools are open-sourced and available under Server Side Public License (all versions released after October 16, 2018) or AGPL v3.0 license (versions released prior to October 16, 2018). Commercial Licenses are also available from MongoDB, Inc.

MongoDB has strong support for dynamic querying and aggregating data including MapReduce and an Aggregation Framework. MongoDB uses BSON (Binary JSON) format for storage purposes and the MongoDB Wire Protocol for communication between client drivers and the MongoDB server. Officially supported Drivers and Client Libraries are available for most popular programming languages, and there are also Community Supported Drivers which offer alternative implementations and support for further programming languages.

The latest MongoDB server releases can be installed via common packaging systems or downloaded as binary archives from mongodb.com.

The current production release series of MongoDB 4.0. It is generally recommended to stay current with the latest minor release of a production release series (e.g. 4.0.x) to take advantage of bug fixes and backward-compatible improvements. For more information on the versioning scheme used by the server, see MongoDB Version Numbers.
