In Object Oriented Programming, it is common to see the composition of
simple classes (and/or instances) into a more complex one. This is a
flexible strategy for building complicated objects and object
hierarchies and can function as a dynamic alternative to multiple
inheritance. There are two ways to perform class (and/or object)
composition depending on the relationship between the composed
elements: <emphasis>Association</emphasis> and
<emphasis>Aggregation</emphasis>.
