SDM: Week 7

Topic: More patterns; Principles of dynamic design

Lectures

Patterns: 

• slides
• video youtube, video mediahopper

Contracts and interaction design: 

• slides
• video part 1 youtube, video part 1 mediahopper, video part 2. (Part 2 is only at YT not MediaHopper because of a technical problem.)

Q&A/discussion: 

Videos

Optional: Joshua Bloch on How to Design a Good API and Why it Matters

Readings

• Martin Fowler on Command-Query Separation
• Martin Fowler on Fluent Interfaces Optional: Wikipedia entry on fluent interfaces (has interesting language examples, but is a bit long-winded).
• Patterns, this week and next. I recommend trying the exercises before doing the reading.

Browse and google as necessary to grok the patterns: e.g. start here or  here. (See the annotated lists in the slides for the patterns you need to know for exam.) 
If you prefer a video presentation, there are lots on YouTube: e.g. here is Derek Banas' explanation of the Strategy pattern - he has a whole series and there are many others. Use whatever material you find useful.
