Interesting post by Paul Nielsen about the Relational Model

Starts out like this:

"I’ve been designing relational databases since the mid 80’s. My conclusion is that the relational model is weak and lacking. Specifically, the foreign key – that simple DRI constraint which is the keystone of the relational model - is insufficient. The model poorly represents reality."

Now, I should note before you think I am trying to incite you to go grab a pitchfork and meet me at his house with an effigy and a bottle of lighter fluid, let's get something straight.  Paul is a good guy and a friend of the relational model and SQL Server specifically.  I agree with his points for the most part, but this could be an interesting conversation, and possible an interesting series of posts:

I left my 2 cents worth as a comment, please add your comments.
