I disagree. Good experience and hard work can teach you why denormalization is 
a bad idea. However, it's not universally a bad idea. It has to be applied to 
what you are trying to accomplish. Formal education helps you to understand 
these problems, however, it is not essential. 
The best data modeller I ever worked with started off spending 20 years working 
for the forestry service, running around in the woods.
