Submit electronically (by midnight) or on paper (by class) your solutions to exercises 6.11 and 6.14 in your textbook. Note that I have intentionally assigned problems that in part use relational algebra concepts that are covered in the textbook, but that we didn't cover in class. [WHAT!?? HE DIDN'T DO THAT, DID HE? Yep, he did.] Consider at least part of these assignments to be a scavenger hunt through chapter 6 to find the material that you need.
