[Data-modeling] [Developers] /architecture schema changes

[Robert Cook]

I'm about to load data on the 1150 tallest skyscrapers in the world  
and I want to be sure that I don't add extra values to any of the  
height properties.  Could you go ahead and make these properties  
unique if you haven't heard any complaints?
