Courses Plus Student 4,462 PointsHow abstract should we get with normalization using foreign keys?
So, theoretically, you could have a separate table or each aspect of a given entry and enter them all into a more inclusive table as foreign keys. For instance, a deck of cards table with the columns of suite, color, value, etc. Each column could be filled with foreign keys here if you wanted, right? Would that be a good idea, or would it just make it hard to read?

This might be a clearer and easier to understand slideshow than the previous one provided:

This one, too:

I hope that helps.
Stay safe and happy coding!

I could explain this, but I'd be reinventing the wheel.
Not only are these great explanations, but they also give graphic data to help you visualize the process better:
