  1. Do Exercises 5.245.30 (relational algebra and tuple relational calculus only), and 5.315.34 (relational algebra only) (p. 141):

The following tables form part of a Library database held in an RDBMS:

  • Book (ISBN, title, edition, year)
  • BookCopy (copyNo, ISBN, available)
  • Borrower (borrowerNo, borrowerName, borrowerAddress)
