Question 2: Given the dependency diagram shown in Figure 1, answer the following questions
a: Identify and discuss each of the indicated dependencies
b: Create a database whose tables are at least in 2NF, showing the dependency diagrams for each table.
c: Create a database whose tables are at least in 3NF, showing the dependency diagrams for each table.
Question 3: The dependency diagram in Fig 2 indicates that a patient can receive many prescriptions for one or more medicines over time. Based on the dependency diagram, create a database whose tables are in at least 2NF, showing the dependency diagram for each table.
Question 4: What is a partial dependency? With what normal form is it associated?
Question 5: What three data anomalies are likely to be the result of data redundancy? How can such anomalies be eliminated?
