  2. Software Design From SWEBOK 2004

  3. Agile Methods

  4. Software Architecture • Model/View/Controller (MVC) • Repository • Client/server, Three-tier (four-tier) • Peer-to-peer • Pipes and filters • Concurrency Events • Error and exception handling Data persistence • Distribution of components Interaction and presentation

  5. Pipes and Filters docx XML XML XHTML

  6. Repository

  7. Model-View-Controller

  8. Patterns • Reusable solutions to common object-oriented programming problems • Creational patterns • Factory Method, Abstract Factory, Builder, Prototype, Singleton • Structural patterns • Adapter, Bridge, Composite, Decorator, Façade, Flyweight, Proxy • Behavioral patterns • Chain of responsibility, Observer, Strategy, Command, Interpreter, Iterator

  9. Nonfunctional Requirements may suggest a design pattern • “manufacturer independent”, “device independent”, “must support a family of products” • Abstract Factory Pattern • “must interface with an existing object” • Adapter Pattern • “must deal with the interface to several systems, some of them to be developed in the future” • Bridge Pattern
