Schools employ professors who are characterized by their unique staff-id, name and the school they work for. A school offers courses that are characterized by their course-code which is unique, course name and the school.

Will there be any problems in creating a Relational Database from your ER diagram? If there is, then describe how you will address this and re-draw the ER diagram.Question 3 (8 Marks)Create the DDL statements to create the tables described in your modifies ER diagram in Question 2.Question 4 (8 Marks)In your Database you created in Question 3, assume there is a student record for student12543 Paul Darbyshirewho is enrolled in the courseBIS Bachelor of Information SystemsIt is the beginning of Semester 1 2020.
