## 文档数据库

### MongoDB

> MongoDB 是一个基于文档的分布式数据库，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 是一个介于关系型数据库和非关系型数据库之间的产品。它是非关系数据库当中功能最丰富，最像关系数据库的。它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。
>
> MongoDB 最大的特点是它支持的查询语言非常强大，其语法有点类似于面向对象的查询语言，几乎可以实现类似关系数据库单表查询的绝大部分功能，而且还支持对数据建立索引。

### Nosql 数据库综合

- Martin Fowler 在 YouTube 上分享的 NoSQL 介绍 [Introduction To NoSQL](https://youtu.be/qI_g07C_Q5I)， 以及他参与编写的 [NoSQL Distilled - NoSQL 精粹](https://book.douban.com/subject/25662138/)，这本书才 100 多页，是本难得的关于 NoSQL 的书，很不错，非常易读。
- [NoSQL Databases: a Survey and Decision Guidance](https://medium.com/baqend-blog/nosql-databases-a-survey-and-decision-guidance-ea7823a822d#.nhzop4d23)，这篇文章可以带你自上而下地从 CAP 原理到开始了解 NoSQL 的种种技术，是一篇非常不错的文章。
- [Distribution, Data, Deployment: Software Architecture Convergence in Big Data Systems](https://resources.sei.cmu.edu/asset_files/WhitePaper/2014_019_001_90915.pdf)，这是卡内基·梅隆大学的一篇讲分布式大数据系统的论文。其中主要讨论了在大数据时代下的软件工程中的一些关键点，也说到了 NoSQL 数据库。
- [No Relation: The Mixed Blessings of Non-Relational Databases](http://ianvarley.com/UT/MR/Varley_MastersReport_Full_2009-08-07.pdf)，这篇论文虽然有点年代久远。但这篇论文是 HBase 的基础，你花上一点时间来读读，就可以了解到，对各种非关系型数据存储优缺点的一个很好的比较。
- [NoSQL Data Modeling Techniques](https://highlyscalable.wordpress.com/2012/03/01/nosql-data-modeling-techniques/) ，NoSQL 建模技术。这篇文章我曾经翻译在了 CoolShell 上，标题为 [NoSQL 数据建模技术](https://coolshell.cn/articles/7270.htm)，供你参考。
  - [MongoDB - Data Modeling Introduction](https://docs.mongodb.com/manual/core/data-modeling-introduction/) ，虽然这是 MongoDB 的数据建模介绍，但是其很多观点可以用于其它的 NoSQL 数据库。
  - [Firebase - Structure Your Database](https://firebase.google.com/docs/database/android/structure-data) ，Google 的 Firebase 数据库使用 JSON 建模的一些最佳实践。
- 因为 CAP 原理，所以当你需要选择一个 NoSQL 数据库的时候，你应该看看这篇文档 [Visual Guide to NoSQL Systems](http://blog.nahurst.com/visual-guide-to-nosql-systems)。

选 SQL 还是 NoSQL，这里有两篇文章，值得你看看。

- [SQL vs. NoSQL Databases: What’s the Difference?](https://www.upwork.com/hiring/data/sql-vs-nosql-databases-whats-the-difference/)
- [Salesforce: SQL or NoSQL](https://engineering.salesforce.com/sql-or-nosql-9eaf1d92545b)
