Suppose that you have the ERM shown in Figure Q3.14.

FIGURE Q3.14

How would you convert this model into an ERM that displays only 1:M relationships? Make sure that you draw the revised ERM. Specifically convert this M:N relationship into two 1:M relationships – look at figure 3.26 to see example for STUDENT and CLASS. Use Crow’s foot diagram as illustrated in Figures 3.17, 3.19, and 3.21 for ERM diagram. Write the business rules that apply to the two 1:M relationships and draw the revised ERM diagram
