MongoDB 是一个基于分布式文件存储的数据库。由 C++ 语言编写。旨在为 WEB 应用提供可扩展的高性能数据存储解决方案。
MongoDB 是一个介于关系数据库和非关系数据库之间的产品，是非关系数据库当中功能最丰富，最像关系数据库的。
NoSQL(NoSQL = Not Only SQL )，意即"不仅仅是SQL"。
在现代的计算系统上每天网络上都会产生庞大的数据量。
这些数据有很大一部分是由关系数据库管理系统（RDBMS）来处理。 1970年 E.F.Codd‘s提出的关系模型的论文 "A relational model of data for large shared data banks"，这使得数据建模和应用程序编程更加简单。
通过应用实践证明，关系模型是非常适合于客户服务器编程，远远超出预期的利益，今天它是结构化数据存储在网络和商务应用的主导技术。
NoSQL 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。

以下实例我们创建了数据库 runoob:
> use runoob switched to db runoob > db runoob >如果你想查看所有数据库，可以使用 show dbs 命令：
> show dbs admin 0.000GB local 0.000GB runoob 0.000GB >可以看到，我们刚创建的数据库 runoob 并不在数据库的列表中， 要显示它，我们需要向 runoob 数据库插入一些数据。
> db.runoob.insert({"name":"菜鸟教程"}) WriteResult({ "nInserted" : 1 }) > show dbs local 0.078GB runoob 0.078GB test 0.078GB >
