Draw an ERD that includes two entities: INSTRUCTOR with attributes (id, name, address, salary) and STUDENT with attributes (student_id, name, address). The relationship between them is ADVISOR. An instructor may be an advisor and can have a maximum of 50 students; each student must have exactly one advisor. Please show cardinality ratios using both Chens notation and IE notation respectively. Note: You can just type text on two ERDs to show cardinality ratios.
