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*丰富，*像关系数据库的。他支持的数据结构非常松散，是类似json的bson格式，因此可以存储比较复杂的数据类型。 对于新手和那些想要获取更多实践知识的有经验用户来说，《MongoDB设计模式(影印版)》(作者科普兰)都是一本必要的读物。
内容简介
无论你正在搭建一个社交媒体网站还是一个内部使用的企业应用，《MongoDB设计模式(影印版)》这本注重实践的指南都可以为你展示出在MongoDB和它所用来解决的商业问题之间的紧密联系。你将学习如何把MongoDB设计模式应用到多个具有挑战性的领域中，比如电子商务、内容管理和在线游戏。通过使用 Python和JayaScript的代码实例，你将了解MongoDB 是如何让你在调整数据模型的同时简化开发流程。很多商业应用在还没有理解如何更有效地使用NoSQL数据库之前就直接启用了它。这本《MongoDB设计模式( 影印版)》(作者科普兰)将为你演示文档嵌入、多态性架构和其他处理特定大数据用例的MongoDB模式的优势所在，包括：营运智能：执行商业数据的实时分析。电子商务：让MongoDB成为产品目录大师或者库存管理系统。内容管理：学习用来存储内容节点、二元资产和讨论区的方法。在线广告网络：把技术运用于广告播放的频次控制、关键字定位和竞价。社交网络：学习如何存储一个仿效Google+的复杂社交图。
在线游戏：为一个多人角色扮演游戏提供对人物和世界数据的并发访问。
