I disagree. Since relational supports objects directly, you still have an OO system. In a strict and precise sense, relational is already an OODBMS.

If you choose a network model OODBMS, you have a network model DBMS with all of the drawbacks that entails. If you choose a relational OODBMS, you have a relational DBMS with all of the advantages that entails.

First, you have to know what you are really choosing between. Are you really choosing between object vs. relational or are you really choosing between network vs. relational.
