Object-Oriented Design Course Material

Lectures

• Intro to the course, overview of the course outline
• Software Processes [pdf] (note: pdf does not cover the Pfleeger material),
  Chapter 2 (pp. 45 - 65) of Shari Lawrence Pfleeger. Software Engineering; Theory and Practice (Second Edition). Prentice Hall. 2001.
  Note: eXtreme Programming (XP) is quite "extreme" in insisting on "merciless" refactoring. Any refactoring operation (be it of code, or of a design) must however preserve "required" properties (typically, functional requirements) while improving other properties (such as re-usability or non-functional requirements such as performance). To give you a better idea of refactoring, www.refactoring.com has a catalog of refactoring patterns.
• Unit Testing in Python. Chapters 13 - 15 in Mark Pilgrim's Dive into Python.
• What does it mean to be Object-Oriented ? [pdf] [OO examples (polymorphism etc.) in Python]
  (Page-Jones Chapter 1. p. 3 - 49).
• UML
• What is? [pdf]
• Class Diagrams [pdf]
  (Page-Jones Chapter 3. p. 85 - 101, Chapter 4. p. 107 - 130)
• Architecture Diagrams, Package Diagrams
  (Page-Jones Chapter 7. p. 188 - 196)
• (Object-)Interaction Diagrams:
  • Communication Diagrams (formerly known as Collaboration Diagrams) [pdf]
    (Page-Jones Chapter 5. p. 137 - 146)
  • Sequence Diagrams [pdf]
    (Page-Jones Chapter 5. p. 146 - 160)
• Behaviour Diagrams:
  • Finite State Automata (FSA) in a nutshell [pdf] and
    how FSAs can be used to recognize patterns specified using regular expresssions. More information about (and examples of) regular expressions can be found at http://www.regular-expressions.info/ and on Wikipedia.
  • Activity Diagrams / Petri Nets [pdf]

Below this line is the material for the final exam.

• Higraphs [pdf], Statecharts [pdf]
  Page-Jones Chapter 6. p. 164 - 181 is optional reading. It is replaced by
  David Harel. On Visual Formalisms. Communications of the ACM, 31(5):514-530. May 1988. (read pages 514 - 523)
  The example Statechart "organically" grown using AToM³ during the tutorial: tutorialExample_DCharts_MDL.py.
• Quality of Design:
  • State Space
  • Intermezzo: FSA/Statechart vs. Class Diagram/methods
  • Substitutability
  • Design by Contract (Eiffel example)
  • Criteria for good OO design: Domains, Encumbrance and Cohesion. Lecture 16, Lecture 17
    (Page-Jones Chapter 9. p. 233 - 253)
• Design Patterns
• Creational:
  • Singleton - [pdf]
    (GoF p. 127 - 134)
  • Abstract Factory [pdf]
    (GoF p. 87 - 95)

• Behavioural:
  • Command - [pdf]
    (GoF p. 233 - 238 and 62 - 64)
  • Observer / Template Method - blackboard notes (last year's presentations are very close to what appeared on the board: [pdf1], [pdf2]) (GoF p. 293 - 300)
  • Visitor [pdf]
    (GoF p. 331 - 336)
• Final Review
