Recently I was looking at the list of new features in Erwin Data Modeler 2020, and one feature caught my eye – Extended Notes.

I knew that I could add a very similar feature to any object in PowerDesigner in less than 10 minutes, with absolutely no programming.
Here’s a simple Logical Data Model – the Entity “Contact Type” has four Extended Notes (one of those has its own Extended Note)

Here’s one of those notes. The properties are all standard, except for Status , Author, and Importance, which I defined in a Model Extension.

These Extended Notes can be compared and merged using the standard PowerDesigner Merge / Compare utility, and I can include them in Reports, List Reports, and Dependency Matrices
