QUESTION 1 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 Sample Value Sample Value SINGER ID 1234 Sample Value 5678 Shakira 1234 SINGER_NAME Britney Spears Britney Spears RECORD STUDIO S1 STUDIO_NAME Studio 1, East Building Studio 1, East Building Studio 2, West Building SONG CODE P1322 P1322 P9375 SONG_TITLE Happy New Year Happy New Year Break The Ice RECORD DATE 01/01/2006 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
