In relation to data modeling and ERD design, explain comprehensively what is meant by the term cardinality (1 mark). In relation to this same issue, how do we represent in our ERD the minimum cardinality? (1 mark) How do we represent the maximum cardinality? (1 mark). Consider the two relationships: a student can enrol in either 1, 2, 3, or 4 courses each semester AND a course can have student enrolments from zero to 500.
