title: Do I understand MongoDB Realm correctly?
body: <p>There are three components:</p>
  
  <ul>
  <li>Realm Database: Local Storage &amp; Persistence </li>
  <li>Realm Sync: Sync Realm Databases between clients and the Mongo DB Atlas </li>
  <li>Mongo DB Atlas:  A Cloud Database.</li>
  </ul>
  
  <p>You can use each separately or together. So you can</p>
  
  <ul>
  <li>Just store data locally with Realm Database and not sync it  </li>
  <li>Just store data on Mongo DB Atlas without using realm sync, using standard
  queries to access the data.</li>
  <li>Use realm sync to create a synced realm that partitions your mongo db atlas database into a local realm and syncs data between the database and all clients who use it.</li>
  </ul>
  
  <p>Is this all correct?
  (Thank you)</p>
