Write a trigger PENALTY_CALCULATION that is executed after updating the borrow table by setting the value of actual_return_date when a borrower comes to the front desk of the library to return a book. The penalty must be calculated based on the above-mentioned business rules in Question 3. [Hints: To get the number of days between two dates: date2 and date1, you may use the following query. select ceil(date2-date1) from table1; sysdate will return the current date.]
