  12. Today’s lecture • Designs • Abstraction • Design notations • Class diagrams • Use case diagrams • Storyboards

  13. Abstraction • Abstractions are formed by reducing the information content of a concept or an observable phenomenon, typically to retain only information which is relevant for a particular purpose • what do I need to know • what do I not need to know • Every design notation supports a certain kind of abstraction
