I’m fairly new to UML and ERD, but I am trying to use the community edition to create an ERD for a database. When I link 2 tables together with a many-many relationship the documentation says that a subtable should be created. When I do it, the GUI immediately defaults into naming the relationship, and after doing that there is no further action. Am I doing something wrong? Need to his a checkmark somewhere? Maybe the community edition doesn’t do that?
May I know you are specify your ERD as a Conceptual ERD, Logical ERD or a Physical ERD? Resolve M:N relationship into 2 x 1:M relationship is available to the Physical ERD only.
The automatic resolve of M:N relationship is only on the Physical ERD (as this is a way to solve a physical implementation in database). You can right click on the blank area of the ERD and select Data Model to switch between different form of data model.
