Suppose you have been given the table structure and data shown in Table P6.9, which was imported from an Excel spreadsheet. The data reflects that a professor can have multiple advisees, can serve on multiple committees, and can edit more than one journal. Given the information in Table P6.9: a. Draw the dependency diagram. b. Identify the multivalued dependencies. c. Create the dependency diagrams to yield a set of table structures in 3NF.
Suppose you have been given the table structure and data shown in Table P6.9, which was imported from an Excel spreadsheet. The data reflects that a professor can have multiple advisees, can serve on multiple committees, and can edit more than one journal.
Given the information in Table P6.9:
a. Draw the dependency diagram.
b. Identify the multivalued dependencies.
c. Create the dependency diagrams to yield a set of table structures in 3NF.
d. Eliminate the multivalued dependencies by converting the affected table structures to 4NF.
e. Draw the Crow's Foot ERD to reflect the dependency diagrams you drew in Problem 9c. (Note: You might have to create additional attributes to define the proper PKs and FKs. Make sure that all of your attributes conform to the naming conventions.)
