怎么判断是单独用一个数据库，还是用多个数据库？

u一般比较大型的系统，业务复杂，数据库存储量比较大，逻辑复杂，可以采用多个数据库，分开了管理，把数据做拆分。

（MySQL独享版）

多个网站可以共用一个数据库么？

u操作方法：每个网站的数据库表前缀不同命名即可，比如dz的默认表前缀是pre_,wordpress的默认表前缀是wp_，如果有相同程序在安装的时候注意一下表前缀就行了。u安全隐患：从技术上来说,可以实现,但是会给后期网站的维护，带来诸多麻烦。例如你这几个站中有一个站的客户空间不再放你这里了，需要你备份资料给他，默认一备份就会把其他几个站的数据库资料也备份进去了，数据库一旦有问题了，几
