  2. Assignment #2/3 (pre-deductions) Average = 67%, S.dev. = 12.5%, max = 90% CSC407

  3. Assignments • I will post ass#1 & #2/3 marks on the web • include assessed late penalties • by student number • please verify that your marks are accurate • When ass#4 is marked, I will add them to the Web • collect ass #4 (and any other uncollected assignments) from the CSSU in the Engineering Annex CSC407

  4. Review • Architecture Introduction • General • How architecture fits into the development process • Definition of architecture (components, relationships, multiple structures) • Influences on and effects of architecture • Importance of architecture • important architectural attributes • Parnas KWIC case study • “On the Criteria To Be Used in Decomposing Systems into Modules” • information hiding • Compared two modularizations for the KWIC system • pervasiveness of the effect of changes CSC407

  5. Review • Design • OOD Introduction • Output of OOA is the “Problem domain component” • transform into a design & add other components • Design Patterns • Introduction • What they are, how they are documented, the space of design patterns • Overviewed a large number of design patterns • Granularity • Inheritance v.s. composition & delegation • LEXI case study • Composite, Strategy, Decorator, Bridge, Command, Iterator, Visitor • Creational Patterns • maze example • Abastract Factory, Builder, Factory Method, Prototype, Singleton • compared & contrasted • Structural Patterns • Adapter, Façade, Flyweight, Proxy (+ Bridge, Composite, Decorator) • Behavioral Patterns • Mediator (+ Command, Iterator, Strategy, Visitor) CSC407
