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 database server and tools, written in C++, are open-sourced and available under AGPL v3.0 license or a Commercial License. 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.
