title: Database design for admin role
body: <p>I am desiging an app that have users who can write different posts(text, file image etc.). In order these posts to be made visible to the other users, there should be an admin who will validate that the content of the post is correct and will give permission for the publishing of the post. I am using relational database.
  What is the best way to design the database in order to support this feature? </p>
