MongoDB

MongoDB develops a document database in which records are stored as JSON-like documents instead of rows and tables, so the data model can change as an application evolves. MongoDB Atlas is the managed service, running on AWS, Azure and Google Cloud, and adds full-text search, vector search and stream processing alongside the core database. MongoDB Enterprise Advanced is the self-managed edition for on-premises or private cloud use, and the Community Edition is free to download. Compass provides a graphical interface to explore and query data, and Relational Migrator helps teams move existing SQL schemas to MongoDB. It is used by developers and engineering teams building web, mobile and data-intensive applications.
