title: Advantage of Django ORM V/S Performing raw SQL queries
body: <p>I have been working with django for the past two years but I still can't see the advantage of using <code>django ORM</code> rather than writing raw SQL queries. </p>
  
  <p>Is there any memory efficiency advantage? Is there any configuration advantage? Is there any data migrations advantage? What are the situations I should use Django orm? </p>
  
  <p>Why should anyone use Django orm over raw SQL queries?</p>
