The table structure shown in Table P6.6 contains many unsatisfactory components and characteristics. For example, there are several multivalued attributes, naming conventions are violated, and some attributes are not atomic. a. Given the structure shown in Table P 6.6, write the relational schema and draw its dependency diagram. Label all transitive and/or partial dependencies. b. Draw the dependency diagrams that are in 3NF. (Hint: You might have to create a few new attributes. Also make sure that the new dependency diagrams contain attributes that meet proper design criteria; that is, make sure there are no multivalued attributes, that the naming conventions are met, and so on.) c. Draw the relational diagram. d. Draw the Crow's Foot ERD
