Quiz 5
Regarding Reading 5.
- What is a relation?
- What is a tuple? Are tuples themselves in any particular order in a relation?
- 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?)
- Using relational model notation, write relations for the following entities and their attributes:
"A car has attributes VIN, hp, color, and hooptie rating."
"A robot has attributes salary, owner name, model number."
- Now draw a table for each of those entities.
