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.

Attribute Name	Sample Value	Sample Value	Sample Value
SINGER_ID	1234	5678	1234
SINGER_NAME	Britney Spears	Shakira	Britney Spears
RECORD_STUDIO	S1	S1	S2
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.
