SQL is a poor realization of a "true" RDBMS
Can you explain this a little more. Why is it a "poor" realization? It seems fine in most cases to me.
It is fine in many cases. It's at the edges where we start to see problems (particuarly with most implementations not fully working with constraints). Also, the 3VL is a mess. Chris Date's book, SQL and Relational Theory, talks about the good parts and bad parts, and how to use the good parts responsibly.
