Abstract:
Software design is hard. But a typical application rarely has more than 5-10% of truly “new” design. Most of the problems that are being solved have been solved before in another application or context. What would be great would be to capture those solutions in a reusable form that is easy to share, so that the industry can collectively learn from its experience. This is the promise of software design patterns, a movement inspired by Christopher Alexander’s novel book on architectural [building] patterns.

But Design Patterns are not a panacea. Misapplying patterns can create overly-complex designs that are difficult to maintain. This presentation will explore some new design patterns including Dependency Injection and some variants of the Model-View-Presenter pattern. We’ll focus on the principles underlying the design choices, and we’ll provide more general guidance on when and how to apply design patterns to improve your design.
