开篇有益:为什么选择MongoDB?
为啥用MongoDB？
赶NoSQL时髦?
Auto-shard等激动人心的特性?
•No! 08年，还都是浮云。
最初的想法是寻找一个可靠的分布式K/V解决MySQL的问题。
NoSQL(NoSQL = Not Only SQL )，意即反SQL运动，是一项全新的数据库革命性运动，早期就有人提出，发展至2009年趋势越发高涨。NoSQL的拥护者们提倡运用非关系型的数据存储，相对于目前铺天盖地的关系型数据库运用，这一概念无疑是一种全新的思维的注入。
所以说，NoSQL不仅仅是产品，更是一项运动!

继续使用Memcached？
决定：寻找Memcached替代品
选中Flare：
证
项目开发1个月后：
（1）个人能力有限，无法解决一些灵异事件
（2）没有开发者社区
（3）不懂日文
新的候选者MongoDB：
胆子大一点MySQL ＋MongoDB?
可实现
据，代码逻辑有些复杂
能否彻底抛弃MySQL?
胆子再更大一点好吧，试试：
MongoDB,就是它了一举两得的加分项：GridFS
力
综上原因，选对了!
有问必答
碑良好
本文参收集网络资料整理，作为我选择MongoDB的一个参考。
