I recently read this very interesting white paper. I really found it very interesting as this one was one very easy to read and humourous white paper related to SQL Server. The white paper is starts with very interesting note regarding Columbus.
Contrary to popular opinion, Columbus did not prove that the Earth is round. Pythagoras, Plato, and Aristotle claimed a round Earth based on philosophic and observational grounds. More impressively, Eratosthenes measured the Earth’s circumference around 240 B.C., a measurement which comes amazingly close to modern values—within 17 percent when taking pessimistic conversions into account and perhaps 2 percent if we’re more generous.
After the introductory humorous start, this white paper right away go to the point asking question.
If we all agree that the world is round, why would anyone willfully flatten it?
This white paper continues to discuss other important feature of SQL Server with regards to flat map and continuously keep on enhancing knowledge as easy read.
