QUESTION 1 1. 1. To keep track of passengers and their tickets, New World, an airline company, uses the table structure shown below. Assuming that the sample data are representative, draw a dependency diagram in Visio that shows all functional dependencies including both partial and transitive dependencies. (Hint: Look at the sample values to determine the nature of the relationships.) Attribute Name Sample Value Sample Value Sample Value PASSENGER_ID 784 678 216 PASSENGER_NAME John Bush Russle Smoke Maria Sounders PASSENGER_TYPE Adult Adult, Adult Child FLIGHT_NUMBER BA72 BA72, AF54 D12 FLIGHT_DESCRIPTION British Airways 72 British Airways 72, Airfrance 54 Delta 12 FLIGHT_DATE 01/01/2010 05/03/2010, 03/10/2011 01/01/2010 2. 2. Using the initial dependency diagram drawn in question 1, remove all partial dependencies, draw the new dependency diagrams in Visio, and identify the normal forms for each table structure you created. 3. 3. Using the table structures you created in question 2, remove all transitive dependencies, and draw the new dependency diagrams in Visio. Also identify the normal forms for each table structure you created. If necessary, add or modify attributes to create appropriate determinants or to adhere to the naming conventions. 4. 4. Using the results of question 3, draw the fully labeled Crow's Foot ERD in Visio. The diagram must include all entities, attributes, and relationships. Primary keys and foreign keys must be clearly identified on the diagram.
