过程中注意事项：
当安装一个表的时候，就会在core_resource中加入一条数据，来记录改数据表的版本情况。
在安装过程中，如果mysql4-install-0.1.0.php有错误，该表不能建立，但是在core_resource表中还是加入了该<setup>的信息，故下次调试的时候记住，到表core_resource中删除对用的那条数据，否则，安装不上~！！！！
2.1
app/ect/modules/
2.2
app/code/community/AQ/Gao/etc/config.xml
app/code/community/AQ/Gao/sql/gao_setup/mysql4-install-0.1.0.php
只需要建这两个文件就可以完成，当然是最简单的方式了。
2.3
编辑config.xml文件
2.3.1

<gao_setup>
<setup>
<module />
</setup>
<connection>
<use>core_setup</use>
</connection>
</gao_setup>
</resources>
</global>
2.4
编辑
mysql4-install-0.1.0.php
一定别把`当成'，擦！！，，，，`````````,此符号是在英文状态下esc下面的那个键打出来的符号，擦！
