Acknowledgment to Dr. Greg Wadley from The University of Melbourne to help us design this assignment. Setup Script To set up the database in your MySQL server, download the file Assignmentsetup.sql from Canvas and run it in Workbench. This script creates the schema and database tables and populates them with data. The SQL queries required In this section are listed 15 questions for you to answer. Write one SQL statement per question. Do not use views or temporary tables to answer the questions. Where it would improve readability, order your output, and use aliases. Format large numbers and fractions appropriately. Beside each question is a maximum mark which reflects the difficulty of that question. Your total score will be scaled to 15% of your overall marks in the subject. Your work will be assessed on the correctness and simplicity of the SQL that you write. (A query that produces correct output but is more complex than it needs to be, for example joining more tables than is necessary, may not achieve full marks, even if it produces the correct results.) 15.
