I said, I am sorry.
I did not claim that it is better, because it is already a political
issue (ok, may be I implicitly meant that but I did not want to say that).
I mentioned this model because there is a description and everybody can
read it and I can answer questions if any.
I mentioned this model as the continuation of long discussion in order
to point to the source of ideas.
To keep things simpler: if you are interested to know more about null values and other general data model issues then read the stuff on conceptoriented.com. If you are not interested then do not read. If there are questions then I can answer.
