MongoDB

MongoDB is an open-source, document-oriented NoSQL database designed for high-performance, scalability, and flexibility, storing data in flexible, JSON-like BSON documents instead of rigid tables. It enables developers to handle large volumes of unstructured or rapidly evolving data, supporting features like horizontal scaling (sharding), automatic data replication for high availability, and powerful query capabilities. "Atlas" is the company's fully managed cloud database service, providing those capabilities on major cloud providers.
