Shock horror - data modelling allows conclusions to be drawn

Data modelling is all about storing information in a way that allows it to be reconstructed usefully. If the database is storing information about people then you should be able to reconstruct it at will. As such access to such systems should be carefully controlled. This is nothing new.

If the guy has anything interesting to say on how you might cut up your data and access privileges so that no single user can access everything at once that might be more interesting but otherwise this non-news and not worthy of the boffin title.
