Homework Assignment #1 MSIS 3333 Remember to make a copy for yourself and one to turn in. 1. Students have a CWID (unique), name and year (like freshman). Some (not all) students tutor other students. A student may have only one tutor or no tutor at all. 2. Just like #2, but students sometimes have several tutors. 3. Lumberjacks use many chainsaws and of course have at least one chainsaw. Lumberjacks have a unique name, a height and an ox color. Chainsaws have a number of teeth and a horsepower rating. Not all chainsaws are owned but nobody shares a chainsaw
