1. To keep track of vendors and products they supply, XYZCorp. 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.) VEND TYPE Non-profit organization Non-profit organization Profit organization Profit organization Profit organization PART CODE 1234 PART DESC Logic Chip VEND NAME Fast Chips VEND ADDRESS PRICE 25.00 Cupertino Smart Chips 1234 Logic Chip Phoenix 22.00 Memory Chip 5678 Fast Chips 18.00 Cupertino Quality Chips Memory Chip Austin 5678 15.00 Memory Chip 5678 Smart Chips Phoenix 19.00 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 forelgn keys must be clearly identified on the diagram.
