Thanks for the clarification.

In this newsgroup, I think it would be clarifying if you called your first category SQL RDBMS.

Fabain Pascal uses the term TRDBMS for "Truly Relational Database Managements System(s)". This term is OK when you want to be explicit about a RDBMS that is truer to the relational model, than SQL RDBMSes can ever be.

Outside this newsgroup, when I hear RDBMS, I know people mean SQL RDBMS and I don't correct them. Inside the group is a different matter...
