MDA - DDL Tranformation

[dmag]

Hi,

I try to use the DDL transformation on a package that contain class A and class B. B inherits from A. After the transformation, I have 2 tables, one for the class A and one for the class B. Between the 2 tables, there isn't any relationship, and in the table for B, there isn’t any attribute from the inheritance relationship.

Where my inheritance relationship has gone

Tables can't inherit from another table.

What is it that you want to see in the transformed ddl?

I know that table can't inherit.

The think that I want to see is the relation between the classes. The leaf class must have the attributs from the root class and it's own attributs to be define. So I am looking for a foreign key, or column duplication, or something like that in the database.
