MongoDB 目前变得越来越有名，我现在开始尝试.

MongoDB currently become more and more famous and I am now starting to give it a try.

问题是，我不知道 MongoDB 如何工作的基本理论(如果重要，我正在使用 mongoid gem)

The problem is, I don't know the underlying theory of how MongoDB is working (am using mongoid gem if it matter)

So I would like to have a comparison on the performance between using MySQL+ActiveRecord and model generated by mongoid gem, could anyone help me to figure it out?

推荐答案

文章标题为:你到底使用 NoSQL 到底是为了什么? 在介绍使用 NoSQL 的利弊方面做得非常好.

The article entitled: What the heck are you actually using NoSQL for? does a very good job at presenting the pros and cons of using NoSQL.

重新我发现了一些我认为相关的关于该主题的最新材料(2014 年发布):NoSQL 还剩下什么?

Re-edit: I found some recent material (published in 2014) on this topic that I consider to be relevant: What’s left of NoSQL?
