The tagline of the Game of Set is: The Family Game of Visual Perception. It is a game of finding matching cards in a selected group of cards. Being a SQL guy, I read this as: SET: The GAME of MATCHing cards. In any database we can select SETs using MATCHing criteria. Where is the GAME? Well, for me, it is a game of trying to solve this puzzle using SQL.
You will see how you can use the different SET operators in Oracle, how you can use JOINs to create a SET of cards, from which you can SELECT a puzzle and also find the SETs in that puzzle.
