title: How do I integrate the FB Javascript API with custom database
body: <p>I am new to <code>Facebook</code> development. </p>
  
  <p>Is it possible to have a website login with <code>Facebook</code> + a <code>non-FB</code> <code>database</code>? </p>
  
  <p>Specifically I would like my users to access <code>Facebook</code> information similar to <code>Sociogram</code> (<a href="http://coenraets.org/blog/2013/02/sociogram-a-sample-application-exploring-the-facebook-sdk-and-the-graph-api/" rel="nofollow">http://coenraets.org/blog/2013/02/sociogram-a-sample-application-exploring-the-facebook-sdk-and-the-graph-api/</a>) which I have gotten working with my own website <code>app</code>, but also tie in additional user information that <code>Facebook</code> does not keep - so that my users only have to have one login. </p>
  
  <p>Any info on where to start researching would be helpful.</p>
