Detailed explanation-1: -An association is a relationship between classes (more precisely, instances of those classes) that indicates some meaningful and interesting connection (see Figure). In the UML, associations are defined as “the semantic relationship between two or more classifiers that involve connections among their instances."
Detailed explanation-2: -Dependency–A semantic relationship in which a change on one thing (the independent thing) may cause changes in the other thing (the dependent thing). (See the examples below.) Association–A structural relationship describing links between objects.
