Thanks Joe, although my point is that you don't get a relational model for your 150 or 500 pounds. Why is that? Why no international standard on relational database model descriptions?

Also, it always occurs to me that it must cost the Royal Mail much more because of the inefficiency due to baldy addressed post than they could ever make from selling their postcodes. I.e. if the postcode database was free, more post would be address correctly and they would *save* money. But then I should not expect to see much sense from a publicly owned organisation.
