title: When to use CouchDB over MongoDB and vice versa
body: <p>I am stuck between these two NoSQL databases. </p>
  
  <p>In my project I will be creating a database within a database. For example, I need a solution to create dynamic tables. </p>
  
  <p>So users can create tables with columns and rows. I think either MongoDB or CouchDB will be good for this, but I am not sure which one. I will also need efficient paging as well.</p>
