How to properly implement many to many relationship in mongodb? Write an array of IDs to the model or through a link table? How would it be more correct?

Answer 2

yes, by the way, any connection options are decided by roles
, only the question of managing these roles arises, but this is all a matter of conventions

Answer 3

If there is a need for many-to-many relationships, then you should look towards relational databases. Monga is not the best solution in this case.
