Suppose that the following are true: - all id column are primary keys in whichever table they are - the dept_id in course table is foreign key that is referencing the id column in the department table - the foreign keys stud_type_id, stud_cat_id in the student table are referencing the id columns in the student_type and student_category tables respectively. the coursecode and stud_id columns in the registration table are foreign keys in the course and student tables respectively. 1. Design an Entity Relationship Diagram for the system above. 2. Write query that would return the names and contacts of all Local students. 3. Write a query that would return names, contact and locations of all departments that has a location text with Ave 3 as part of it. [hint: use the LIKE clause with "_" or "%"]
