How can I solve this question?:

To keep track of vendors and products they supply, XYZ Corp. uses the table structure shown below.

For Question $1,$ 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.$)$

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.

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.

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.
