Online Day to makeup 3/5

Some of your activity diagrams would have been better communicated as state diagrams. Watch this quick video I made first to explain a state diagram. If that is not helpful, try these tutorials.

• my state diagram video
• If that does not make a state diagram clear, please watch this video http://www.youtube.com/watch?v=_6TFVzBW7oo OR read this tutorial on state machines: http://www.agilemodeling.com/artifacts/stateMachineDiagram.htm

Your technical specification may also need a class diagram. (If you are creating classes inside your code, you will need a class diagram.) Read through this tutorial that wonderfully shows how the code matches the arrowheads: http://www.cse.buffalo.edu/faculty/adrienne/ClassResources/ClassDiagramsInANutshell/

In order to do object oriented design, you may want to use standard design patterns.

Design pattern introduction: http://www.developer.com/java/other/article.php/3325211/What-Are-Design-Patterns.htm

Drill down on one pattern in order to understand patterns:

• factory pattern example: http://www.tutorialspoint.com/design_pattern/factory_pattern.htm
• factory pattern details: http://www.oodesign.com/factory-pattern.html
• factory tutorial: http://www.newthinktank.com/videos/design-patterns-tutorial/

All Gang of Four Design Patterns: http://www.oodesign.com/ OR use http://www.tutorialspoint.com/design_pattern/

We will cover the burn down chart in class, so do not worry if you cannot complete the chart by 3/10, as long as your specification is done. Do email questions to me if you have any questions about how to complete the technical specification by 3/10.
