L7-S4Modeling Fall 2002 SJSU – CmpE M.E. Fayad Generalization, Specialization Related terms: inheritance Definition: –Inheritance is a programming language concept; an implementation mechanism for the relationship between superclasses and subclasses by means of which attributes and operations of a superclass also become accessible to its subclasses.

L7-S5Modeling Fall 2002 SJSU – CmpE M.E. Fayad Generalization, Specialization Notation: –The inheritance relation is represented by means of a large empty arrow pointing from the subclass to the superclass. Superclass Subclass

L7-S13Modeling Fall 2002 SJSU – CmpE M.E. Fayad Sequence Diagrams Related terms: interaction diagram, event trace diagram, scenario, message diagram. Definition: –A sequence shows a series of messages exchanged by a selected set of objects in a temporally limited situation, with an emphasis on the chronological course of events.
