Resolving EERD and Project (both)

3:13pm Thu 12th Sep, Henry Y.

Hi all, I am a bit confused as to how we resolve our many to many relationships.

>From what I can see we place a new Entity in between the two Entities in order to resolve it.

In regards to the project does this mean we need new relationships between the two, or is that new entity a relationship with attributes? Furthermore does this mean the relationship/entity belongs in the entity dictionary or relationship dictionary. Thank you,

We resolve many to many relationships usually by create a new relation (table). However, that is part of the logical modeling.
