什么是规范化，应该在哪里有用，以及我们如何实时使用规范化.

Hi to all,
what is Normalization, where it should be useful and how can we use normalzation in real time.

推荐答案

这个问题并非完全不正确，但可以大大改善.您应该重新编写它:

什么是Wikipedia，Google，CodeProject和StackOverflow.com?"

如果您提出要求并获得了很好的答案，就不需要像您原来的问题了！

现在，答案并不像您想的那么简单.用一个简短的答案来解释绝对是不可能的.这是一篇相当大文章的话题.自己看:

http://en.wikipedia.org/wiki/Normalization_%28database%29 [ ^ ].

普通形式:
http://en.wikipedia.org/wiki/First_normal_form [ http://en.wikipedia.org/wiki/Second_normal_form [ http://en.wikipedia.org/wiki/Third_normal_form [ http://en.wikipedia.org/wiki/Fourth_normal_form [ http://en.wikipedia.org/wiki/Fifth_normal_form [ http://en.wikipedia.org/wiki/Sixth_normal_form [

This question in not completely incorrect, but can be greatly improved. You should have re-formulated it:

"What are Wikipedia, Google, CodeProject and StackOverflow.com?"

If you asked and got good Answers, the Questions like your original one would not be needed!

Now, the answer is not that simple as you might think. It''s absolutely impossible to explain in one short answer. It''s rather a topic of quite a big article. Look by yourself:

http://en.wikipedia.org/wiki/Normalization_%28database%29[^].

Normal forms:
http://en.wikipedia.org/wiki/First_normal_form[^],
http://en.wikipedia.org/wiki/Second_normal_form[^],
http://en.wikipedia.org/wiki/Third_normal_form[^],
http://en.wikipedia.org/wiki/Fourth_normal_form[^],
http://en.wikipedia.org/wiki/Fifth_normal_form[^],
http://en.wikipedia.org/wiki/Sixth_normal_form[^].

Good amount of reading, isn''t it it?
