To which category of database management systems does MongoDB belong?

MongoDB belongs to the category of NoSQL database management systems, specifically — document-oriented databases. Unlike relational DBMSs, MongoDB stores data in BSON format (binary JSON), which allows flexible handling of unstructured and semi-structured data.

Main features of MongoDB:

• Data is stored in collections of documents, not in tables.
• No strict schema, which makes it easier to change the data structure.
• High scalability and support for horizontal sharding.

This makes MongoDB a convenient choice for applications with dynamic data and requiring rapid development.
