DDL transformation of inheritance hierarchies

[mcoletti]

I have a logical PIM model, with some generalization relationships among classes. To be specific, I have an abstract main class (A), and some concrete subclasses (B, C, ..) inheriting from A, with a normal generalization association.

When I perform the transformation in DDL of this package, the following happens:

• A is generated as a table (why, if it is abstract?)
  B, C, does not include the attributes defined in A (I would expect this, as they are inherited from A)
  
  
• Are my assumptions wrong?
  
  
• Did anyone find similar problems?
  

I also take a look at the transformation template, but there is no way to add a template for “generalization”  , maybe this is an explanation.

Happy new year!
