1. To keep track of singers and their recordings, the ABC recording 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 SINGER ID SINGER NAME RECORD STUDIO Sample Value 1234 Britney Spears S1 Sample Value 5678 Shakira S1 Studio 1, East Building P1322 Sample Value 1234 Britney Spears S2 Studio 1, East Building P1322 Happy New Year 01/01/2006 STUDIO NAME Studio 2, West Building SONG CODE SONG TITLE RECORD DATE P9375 Happy New Year Break The Ice 05/03/2005 01/01/2008 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
