How do you handle relationships in MongoDB (e.g., one-to-many, many-to-many)?

In MongoDB, relationships can be handled in two ways:

• Embedded documents: Storing related data within a single document (best for

one-to-many relationships).

Example: A blog post with comments as an embedded array.

• Referenced documents: Storing related data in separate collections and using

references (best for many-to-many or large datasets).

Example: A customer document may reference an order document by storing the

order’s _id in the customer document.
