title: Databases using JSON as storage/transport format
body: <p>How many database systems there are that use JSON for storage or transport? I know of:</p>
  
  <ul>
  <li><a href="http://couchdb.apache.org/" rel="noreferrer">CouchDB</a></li>
  <li><a href="http://www.mongodb.org/display/DOCS/Home" rel="noreferrer">MongoDB</a></li>
  <li><a href="http://code.nytimes.com/projects/dbslayer" rel="noreferrer">DBSlayer</a></li>
  </ul>
  
  <p>I remember I saw yet another vendor in a SO user's profile. That systems was using what they called binary JSON, but I can't remember the name of the product.</p>
  
  <p>Lately, it appears that more and more DB projects are looking towards JSON for persistence storage. Some of them are even embracing HTTP as a transport layer.</p>
