Describe the specific data anomalies that exist

I need help answering the following questions:

 

1) Is this relation in at least 1NF? Why or why not?

2) What is the primary key of the initial relation (assume the values shown are the only possible tuples for all time)?

3) Describe the specific data anomalies that exist if we DELETE the tuple containing Jacqueline.

4) Draw a functional dependency diagram for the initial relation. This diagram should agree with the primary key you selected in above.

5) Based on your diagram, what normal form is the initial relation in? Why?

6) If necessary, decompose the initial relation into a set of non-loss 3NF relations by showing the relations, attributes, and tuples. Show complete relations with attribute headings and all data values in the tuples of your relations. Determine the number of 3NF relations you end up with after normalization, write this number, and then circle the number.

 

I need to examine the following relation and its attributes. Also I need to correctly identify the normal form of initial relation, primary key of initial relation, describes data anomalies, develop functional dependency diagram of initial relation and develop the proper set of 3NF relations via normalization.

 

I have attached the instructions to further explain the task and scenario. Thank you.
