MongoDB is a flexible and scalable storage alternative to relational databases that utilizes binary JSON to simplify coding and group relevant data together internally, allowing applications to model data in complex hierarchies while remaining indexable and query-able. MongoDB scales horizontally using auto-sharding with built-in support features, enabling rapid application growth. The database comes packed with frontend tools such as a powerful data management tool, administrative interface, and monitoring plugins, making it developer-friendly with official drivers for 12 programming languages and extensive platform support.
