title: Using External data source on Dynamics CRM
body: <p>I'm creating an Entity in Dynamics CRM 2015 and I want to add new Lookup field and bind that Lookup to an external data source using OData services or other methods that allow me to read data.</p>
  
  <p>Is it possible technically or I'm in the wrong path to <strong>read data from external data source</strong> and use it in Dynamics CRM.</p>
  
  <p>I also have no experience in Dynamics CRM SDK, If it is possible by using SDK please tell which topics I should search for.</p>
