This article turned out better than I thought it would.

Here's why: "In this article we present a mathematical data model for the most common noSQL databases—namely, key/value relationships—and demonstrate that this data model is the mathematical dual of SQL's relational data model of foreign-/primary-key relationships."

Seeing the author immediately increased my expectations: http://en.wikipedia.org/wiki/Erik_Meijer_(computer_scientist...

Erik Meijer gave a presentation on this during YOW 2010, in Melbourne. The ideas are very deep, and I hope they will be taken on board by the IT industry and find practical applications. It would be nice to think that at YOW we witnessed part of the birth of an idea, that will revolutionise the way think about data storage.

That was a fantastic conference. I enjoyed Erik's presentations. Guy Steele's lecture was also very good, but his keynote with Richard P. Gabriel was incredible. He's actually done the 50 in 50 keynote before: http://blip.tv/file/1472720

I agree. If noSQL/SQL vendors start providing a common query mechanism for both SQL and coSQL, it will lead to huge adoption of noSQL products resulting in a huge transformational effect on data persistence.
