title: How to use relations between documents and collections in MongoDB
body: <p>I have the following document in collection <code>objects_parameters</code>:</p>
  
  <pre><code>{
      "_id" : ObjectId("5922ef07470e6cc50c3c987d"),
      "object_id" : "5922ef07470e6cc50c3c987c",
      "parameter_id" : "5922e986470e6cc60c3c987e",
      "value" : "5922e986470e6cc60c3c987e"
  }
  </code></pre>
  
  <p>As you can see, the <code>value</code> field contains (references) the <code>_id</code> of another document from the <code>parameters</code> collection.</p>
  
  <p>How can I <em>bind</em> these two collections using that <code>value</code> field?</p>
