MongoDB stores data in flexible, JSON-like documents, meaning fields can vary from document to document and data structure can be changed over time

The document model maps to the objects in your application code, making data easy to work with

Ad hoc queries, indexing, and real time aggregation provide powerful ways to access and analyze your data

MongoDB is a distributed database at its core, so high availability, horizontal scaling, and geographic distribution are built in and easy to use

MongoDB is free and open-source, published under the GNU Affero General Public License
