Extra Credit For this extra credit assignment you are required to give relational algebra and tuple calculus expressions for each of the (13) queries for the university enterprise (see “A University Database” under the course slides section of the class website). These should be handed in by Monday July 13th. Note that you are only required to do queries #11 and #12 in relational algebra. Finally, this assignment is open book and open notes, but must be done individually, and you should not look up answers on the internet.
