Kindly help me solve this SQL:- University “A” has decided that a new database system is needed for reporting students’ grades. • Students at this university are identified by their student ID, and the database system should store their names and major area of study. • Units in a degree course are identified by the Unit ID. • For each unit within a degree course, the database system (DB) should capture the unit title, unit location of offer and the name of the instructor. The database system should therefore store the grade for each student studying every unit in the degree course. Question 1: Describe the elements of the table of this database system. Question 2: Draw the Entity Relationship Diagram (ERD) of the generated tables. Question 3: Write the SQL code to create the tables.
