  1. What is a relation?
  2. What is a tuple? Are tuples themselves in any particular order in a relation?
  3. How would you generalize the problems Codd tries to address in his original paper? (In other words, does he address architectural problems? Performance problems? What?)

    "A car has attributes VIN, hp, color, and hooptie rating."
    "A robot has attributes salary, owner name, model number."
