Yes, multiple levels will be supported in the suggested design. All I
was saying is that the JPA-style vertical inheritance approach seems
to imply a strict single-join-table-per-subclass mapping. While with
flattened attributes, you can (theoretically) mix and match where

What I probably should do is create a simple project using
single-table inheritance, point it at a relevant subset of my current
project's schema structure, and see exactly what it looks like in the
modeler and in the generated code.

I'm not complete certain I understand the design -- I don't have any
experience with single-table inheritance. It sounds ok for as much
as I do understand. The only concern I have is that the wording
below seems to indicate that only two tables are involved (the root
table and the subclass tabl
