title: Does redis have documents and collections?
body: <p>I am new to redis. I am coming from mongodb. I have read on the <a href="https://redis.io/topics/data-types" rel="nofollow noreferrer">data types redis supports</a>. I was wondering does redis group its data in documents and does it have collections?</p>
  
  <p>I have seen that you can have different databases in the same redis server <a href="https://github.com/NodeRedis/node_redis#usage-example" rel="nofollow noreferrer">here</a> where you can select database 3 instead of the default 0.</p>
