b. Draw a dependency diagram that shows all functional dependencies in the relation, based on the sample data shown.
c. Give an example of one or more anomalies that can result in using this relation.
d. Develop a set of relations in third normal form. Include a new column with the heading Violation in the appropriate table to explain the reason for each ticket. Values in this column are: expired parking meter (ticket code 1), no parking permit (ticket code 2), and handicap violation (ticket code 3).
