  1. Ch.6 Class Diagrams Structural model: a formal way of representing the ______ that are used and created by a business system. conceptual model  design model (design phase) Class: general template that we use to create specific ______ or ______ in the application domain  application domain class Attribute: a piece information that is relevant to the description of the class Operation: behavior of the class converted to ________ (related to implementation) domain specific operation

  2. Relationships: - Generalization Subclass inherits _________________ of their superclass contains ___________________________. a-kind-of relationship cf. specialization - Aggregation Composition relationship a-part-of or a-member-of - Association Patient schedules an appointment. Patient is a-pat-of an appointment? Y/N semantic difference

  3. Class-Responsibility-Collaboration Card (CRC Card) Responsibility: - Knowing knows the value of its _______ and its _______ - Doing can executes its _______ Collaboration: Client object  Server object  Contract  Elements of CRC Card: Fig. 6-1
