1. When designing an E-R model, what is the best strategy to follow?

2. Give examples of 1:1, 1:N, and N:M relationships (other than those presented in this chapter). Draw two E-R diagrams for each of your examples: one using the traditional diamond notation and one using IE Crow’s Foot notation.

3. Give an example for which the maximum cardinality must be an exact number other than those presented in this chapter).
