Background: I took a very basic Info Systems class in college that had a section on Access, so I understand a little about databases, Primary Keys, and one-to-many, many-to-one, etc. relationships. I have also taken MITx 6.00x and most of LPTHW. I am currently taking Django's poll tutorial. https://9apps.ooo
My question is about Foreign Keys. Im not really sure what they are doing and why they are necessary. I'm at the end of the first section of the Django tutorial and trying to get a good understanding of the API. This is the things that is really confusing me. https://solitaire.onl/
