Construct	Description	Syntax
association	A relationship between two or more classifiers that involves connections among their instances.
aggregation	A special form of association that specifies a whole-part relationship between the aggregate (whole) and the component part.
inheritance	A relationship among classes where one class shares the structure and/or behavior defined for one or more other classes. Inheritance is the mechanism that makes generalization, subclasses, and superclasses possible.
