Mongoose Relationships

Mongoose allows developers to model relationships between documents, even though MongoDB itself is a non-relational database.

Referencing Documents

Relationships are often modeled using references, where one document stores the ObjectId of another related document.

Mongoose's populate feature automatically replaces referenced ObjectIds with the actual document data when querying, simplifying related data access.

Deciding between embedding and referencing depends on how frequently related data changes and how it's typically queried together.
