1. To keep track of vendors and products they supply, XYZ Corp. 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.) PART_CODE PART_DESC VEND_NAME VEND_ADDRESS VEND_TYPE PRICE 1234 Logic Chip Fast Chips Cupertino Non-profit organization 25.00 1234 Logic Chip Smart Chips Phoenix Non-profit organization 22.00 5678 Memory Chip Fast Chips Cupertino Profit organization 18.00 5678 Memory Chip Quality Chips Austin Profit organization 15.00 5678 Memory Chip Smart Chips Phoenix Profit organization 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 foreign keys must be clearly identified on the diagram.
