Question

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. 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. 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. 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. I NEED THE ANSWER FOR QUESTION 4 AND THE DRAWING FOR QUESTION 1 THANKS

Answer 1

Below is the required dependency diagram:

It includes all the dependencies as given in the table. There exists partial dependencies.

We can remove these dependencies and split into one new table named TICKET.

Below is the ERD in crows foot notation:

This completes the requirement. Let me know if you have any questions.

Thanks!
