$14-15.$ Give an example of aggregation. Your example should

include at least one aggregate object and three compo$-$

nent objects. Specify the multiplicities at each end of all

of the aggregation relationships. $($Reference Photo$)$Figure $14-15$a shows an aggregation structure of a university. The object diagram

in Figure $14-15$b shows how Riverside University, a University object instance, is related

to its component objects, which represent administrative units $($e$.$g$.,$ Admissions,

Human Resources$)$ and schools $($e$.$g$.,$ Arts and Science, Business$).$ A school object $($e$.$g$.,$

Business$),$ in turn, comprises several department objects $($e$.$g$.,$ Accounting, Finance$).$
