You can, for instance, update a user's email address or reset their password by matching their unique identifier. Delete: Deleting unnecessary or outdated data from a collection is essential for maintaining database efficiency. You can delete a single document or multiple documents at once. For example, you can remove all users who have deactivated their accounts.
