In chapters 23 and 24 of Iteration 2, receive a quick analysis update on system development projects. Learn about the refined use cases, enhanced system sequence diagrams, specialized domain models, and system operation contracts. Explore the concepts of generalization and specialization in class hierarchies, including superclass abstractions and concrete implementations. Get insights into external system integration and special square representation in case studies.

Chapters 23 and 24 Iteration 2 – Quick Analysis Update
From Iteration 1 to 2 • Iteration 2 begins with quick update: • Use cases – 80% in fully dressed form • System sequence diagrams – in the POS case study, add support for third-party external systems with varying interfaces • Domain Model – in the Monopoly game case study, include representation of special squares. • System operation contracts
Generalization and Specialization Generalization: the activity of identifying commonality among concepts and defining superclass (general concept) and subclass (specialized concept) relationships. • Generalization-specialization class hierarchy. • Declare superclasses as abstract. • Append the superclass name to the subclass.
