In SAP PowerDesigner 16.6.4, the Architecture Area concept was made available in most model types, having previously only been available in the Enterprise Architecture model. Perhaps it was a response to the introduction of “Business Data Objects” to ER/Studio Data Architect by Idera. I think “Architecture Area” is a better name than “Business Data Object”.
Anyway, I’m curious – how are you using them in your models?
In this made-up example there are three Architecture Areas, including one that is a child of another.
