php怎样实现大型数据库解决方法
php怎样实现大型数据库
公司的网站用的是PHP+mysql做的，但是据我知道的公司有很多信息都是要从网站里查询的，财务报表数据的查询，操作部的工作业绩查询都是在里面找的，而且数据存储时间是2年，我在想这么大的数据库MYSQL应该是不能胜任的。为什么公司能做到这一点呢？？我只晓得公司的服务器是LIUNX服务器，请各位大侠解决下小弟的遗憾。他们用的是什么技术，怎样学到这种技术。我对PHP也是东一点的。
------解决方案--------------------
一般衡量一个数据库数据量的标准是以 单表XXX行数据衡量的
一般衡量一个数据库的处理能力是以每秒处理多少次查询（读/写）
最多能单表多大数据取决于机器的物理性能（主要是磁盘分区格式所能支持的最大单个文件数比如FAT32是4G，其他的都是几个T的数据），mysql的文档上说有的公司用mysql支持单表几亿条数据，也有听说过单表上亿条的国内企业，这个没验证过，但是我们在个人的PC上跑上百万条记录跟玩似的, MSSQL也就是50万级的数据库，要真比性能MS的还真不一定能比的过，但是MS和oracle的之类的数据库强在有一个强的的SQL解析引擎，可以更方便的解决更复杂的业务逻辑而已。
总之工具是没问题主要就是看用工具的人怎么去用这个工具了，我相信一般的公司两年的业务、财务什么乱七八糟的处理起来跟玩一样的
