New topic added to online #PowerDesigner Excel Import course – Importing subtype hierarchies in Barker Notation.

I’ve added a new topic to the ‘Special cases’ section of my online training course for the PowerDesigner Excel Import Wizard – “Importing subtype hierarchies in Barker Notation”.

Barker notation is available in the Conceptual and Logical Data Models, and it handles entity hierarchies differently from other notations – a sub-type entity is actually owned by the super-type entity, and they are depicted in diagrams as ‘boxes within boxes’. There are no Inheritance objects involved, so the Excel Import must be fed different information.

That’s the real beauty of online training courses — new material can be added at any time.
