MongoDB does not natively support the relational model and its typical relationships like JOINs, which are commonly used in SQL-based databases and handled by ORMs (Object-Relational Mappers). MongoDB is a NoSQL database, and it uses a document-oriented model instead, where data is stored in JSON-like documents.

In MongoDB, relationships are typically managed in a different way, like by embedding documents or using manual references between them, but it doesn't have the automatic relationship management features that ORMs provide for relational databases.
