万事开头难

学习SQL也是，网上一大堆教程，书店一大堆书。就是没有一本告诉你怎么开头。直接一开头就冒出一大堆概念～～其实这表明那些书都是你抄我我抄你的。

我根据自己的学习过程写了一些笔记，由于我是按照自己的思维去思考的，所以有些地方的顺序会没有顺序～～。不过99 能看懂的。-It is the first step that costs troublesome. For SQL learning, a lot of tutorials,books online. But no one tell you how to begin. Just a lot of concept in the beginning~ ~ in fact, those books are copyied from each other. When I learn SQL Server 2000.I make some notes.　

Though these notes are not listed in a good order. But it may be easy to understand.
