07: One-to-Many, Many-to-Many

Using the concept of table "linkage" with primary keys I introduce the concepts of a "one-to-many" and "many-to-many" configuration for data. I don't get too formal, but I do explain how SQL works best when you think through how tables are connected. This is a foreign concept in the programming world since most of the connections between objects is usually one-to-one though a variable or attribute. I also spend some time translating this SQL concept to JavaScript objects.
