in fact, given that one human entitymay carry different names, sexes, dates of
birth [1] from time to time, there is some merit in using one table to hold
identity, the rest or majority of the fields being linked from other tables,
whose key is the identity from the first one.
This applies to addresses, telephone and other contact numbers and so on.
This is precisely the data approach used in the OMG PIDS specification. It doesn't
mean that it has to be stored in that form. I think it is a bad idea to link
the data interchange format to the data storage format. You might choose
to do that, but there is no reason one has to.
