Need more details about movie schema edges

Moved from GitHub tutorial/72

It is not obvious to the person who reads movies DB from tutorial for the first time about existing edges, please paint image with schema relationships, it will help a lot. Thanks.

@campoy The tutorial doesn’t support images, what would be the best workaround for this? I can create a kind of diagram for this. But no idea how to increment to tutorial with this.
