Explain what is meant by the constrained write rule, and explain how to test whether a schedule is serializable under the constrained write rule. Using the above method, determine whether the following schedule is serializable:
S = [R 1 (Z), R 2 (Y), W 2 (Y), R 3 (Y), R 1 (X), W 1 (X), W 1 (Z), W 3 (Y), R 2 (X), R 1 (Y), W 1 (Y), W 2 (X), R 3 (W), W 3 (W)] where R i (Z)/W i (Z) indicates a read/write by transaction i on data item Z.
Many programs written with inheritance could be written with composition instead, and vice versa. Rewrite class BasePlusCommissionEmployee of the CommissionEmployee–BasePlusCom- missionEmployee hierarchy to use composition rather than inheritance. After you do this, assess the relative merits of the two approaches for designing classes CommissionEmployee and BasePlusCom- missionEmployee, as
well as for object-oriented programs in general. Which approach is more nat- ural? Why? What will be an ideal response?
