MongoDB is a cross-platform, document-oriented NoSQL database program. It is classified as a NoSQL database because it does not rely on the traditional table-based relational database structure. Instead, MongoDB uses a flexible, JSON-like document model called BSON (Binary JSON) to store data in collections.
