Real world application usually involved object oriented, because human usually thing about object and their relationship. The artice show the difference between object oriented and database view of information. This is what we usually call ORM (Object Relational Mapping). This is the very reason why ORM frameworks are needed.

Same question, different point of view, different answer, same solution if we had the connector.
