title: How to implement primary key / foreign key between two parse tables?
body: <p>Is there a way to make primary key and foreign key relationship with Parse tables? If yes, how?</p>
  
  <p>I've two tables:</p>
  
  <h3>User Table:</h3>
  
  <blockquote>
    <p>uId (primary key/string) | uName (string) | uAge (number) | uGender (string) | uLocation (string)</p>
  </blockquote>
  
  <h3>Employment Table:</h3>
  
  <blockquote>
    <p>eId (unique/string) | eType (number) | eSalary (number) | uId (foreign key/string)</p>
  </blockquote>
  
  <p>So that, if I'll delete an entry from User table, it'll delete all entries for that particular user in Employment table.</p>
