It isn't clear from your question whether the data in the tables is
_the same_ in these cases. If so, then you could have various child
tables inherit the parent, and the parent would be the largest of all
the tables (the child tables without the columns in question would
just have those columns null). But in general, my impression is that
you don't want inheritance here. What you probably want is better
normalization of your data on the way in.
