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.
