COMP 612              Principles of Database Programming                  Week 3

				   Assignment 3

Use the relational algebra to formulate the queries from Assignment 1 on the 
three relations of the cars database you designed in Assignment 2.

Shared marks for shared work: assignments should be your own work; marks
for joint assignments will be divided by the number of collaborators.
But please feel free to work in groups to learn or for extra work that
is not for marks. HINT: treat your own work for marks as top secret; treat
others' work, if you come across it, as personal and private to them.
