All versions of MongoDB - a scalable, high-performance, open-source, document-oriented database.
MongoDB
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 Map-Reduce and an Aggregation Framework. MongoDB uses BSON (Binary JSON) format for storage purposes and the MongoDB Wire Protocol for communication between client drivers and MongoDB deployments. 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.
