I have a class diagram of three classes; VEHICLE, CAR, and MOTORBIKE.  CAR and MOTORBIKE are specializations of the VEHICLE CLASS.

I'd like to do a DDL transform on this class diagram so I have only 2 tables; CAR and MOTORBIKE, and these tables have fields for all the extended attributes + inherited attributes from vehicle (aka concrete classes)

How do I go about this? using the standard DDL transform I get a table for each class and if I only select the derived classes the transform doesn't include the inherited attributes

General Board / Linking a Logical data model to database builder model
« on: December 06, 2017, 09:14:02 pm »
I'm using Enterprise Architect for the first time. I'm trying to model a database and I'm struggling to understand how to 'link' conceptual, logical, and physical data models.

For example if I change the multiplicity between two classes in my conceptual model would it / could it change the logical model? or if I add an attribute to my logical model would it / could it change my physical model.

And how can I see inconsistencies between the different models?
