  1. V V association connection between classes representing either logical relationships or message paths generalization the abstraction of common features among classes by the creation of a hierarchy of more general classes (superclasses) that encapsulate the common features dependency a relationship between two model elements such that a change in one element may require a change in the dependent element aggregation a whole-part association between two or more objects that represent the whole and the other parts of that whole composition aggregation where no part can belong to more than one composition at a time and if the composite whole is deleted its parts are deleted with it
