Change the purpose and/or the context, and it's usually wrong.  Even
(actually, especially) at the table level.  A table is inevitably and
inextricably bound to a perspective.
That's why a good data model is essential, especially one that includes some of the context. It's only later that the time comes to choose xml (or not) for interchange, or table design for the database.

OTOH, if you have the context and perspective, you can accomplish a lot. I know a man who had to come up with a new large enterprise database system for a client. All he had to work with was the old IBM terminal screens - I think it was screen grabs of the terminal screens, in fact. No code, no database design, no business rules. He developed a relational database system to do the same things that had been done with the terminal screens. It was a big success.
