title: How can I create an entity relationship model?
body: <p>I have some confusion / difficulties trying to draw and understand an ERD diagram, below are the question:</p>
  
  <blockquote>
    <p>“Students enrol at colleges which offer courses taught by teachers.  When the students enrol they must register on the courses they wish to study.  The college will then assign a tutor, who is a teacher, to the student.”</p>
  </blockquote>
  
  <p>Would this be the right diagram? </p>

  <p>Should college be an entity or attribute of the student entity? </p>
