Inheritance in CDM/LDM models in PowerDesigner 15.3?
I downloaded PowerDesigner 15.3's trial version, and I want to build a Logical Data Model of a database. The problem is that this database must use inheritance heavily, and I can't find a way to build an inheritance relationship... The 'Inheritance' button is in fact the only disabled button in the pallete, and I can't find a way to enable it... Did anyone else have this problem too? How can I enable it?
Thank you very much.
Solution
I can only guess that your model is using the Barker notation.
Try to select another notation in the Tools > Model Options dialog.
For example Choose E/R+Merise.
