Strange. In our trade most great people are largely self taught in the
areas they are great in - the industry is new, and people are coming
up with innovations all the time.
Linus Torvalds came up with lots of really cool stuff when he wasn't even a Master. Sergey Brin and Larry Page do have PhDs, and they came up themselves with what makes them great.
Returning to normalization, it is not a very complex theory. When I was getting my education, it did not exist yet, but if it did, it would be taught in my first year, and it would be an easy course. In a top notch university you have to learn a lot of more advanced math to get your Master's degree. More to the point, for me as a development lead, as well as for many DBAs, normalization is just one of many challenges, and a relatively easy one to put it mildly.
Memorizing last names has nothing to do with the ability to administer databases. Names of inventors are forgotten and or omitted all the time. This is especially true for foreign names. Consider periodic table of the chemical elements - it is being taught in American schools, but the Russian name of its inventor is rarely mentioned. Similarly, names of inventors on Normal Forms may be omitted of forgotten, especially in other countries, and that is OK just as well. Received on Sat Mar 08 2008 - 19:08:40 CST
