Chapter 4, Problem 4.41PAE

The Public Safety office at Millennium College maintains a list of parking tickets issued to vehicles parked illegally on the campus. Table 4-6 shows a portion of this list for the fall semester. (Attribute names are abbreviated to conserve space.)

Convert this table to a relation in first normal form by entering appropriate data in the table. What are the determinants in this relation?
Draw a dependency diagram that shows all functional dependencies in the relation, based on the sample data shown.
Give an example of one or more anomalies that can result in using this relation.
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).
Develop an E-R diagram with the appropriate cardinality notations.

Dijkstra's Algorithm (part 1). Consider the network shown below, and Dijkstra’s link-state algorithm. Here, we are interested in computing the least cost path from node E (note: the start node here is E) to all other nodes using Dijkstra's algorithm. Using the algorithm statement used in the textbook and its visual representation, complete the "Step 0" row in the table below showing the link state algorithm’s execution by matching the table entries (i), (ii), (iii), and (iv) with their values. Write down your final [correct] answer, as you‘ll need it for the next question.
