Refactoring to Deeper Insight: Lessons Learned Applying Domain-Driven Design (DDD) - Paul Rayner and Dan Sharp

This presentation shows what we learned during a recent redesign of the video camera support in Nexia Home Intelligence (www.nexiahome.com). Nexia is a large-scale Ruby on Rails application with a customer base using tens of thousands of video cameras. We’ll walk through examples of key design decisions and show code samples to illustrate refactoring the video camera code towards ubiquitous language, a rich domain model, better performance and scalability, and cleaner module boundaries. Learn how applying pair programming, TDD, and Domain-Driven Design (DDD) techniques enabled us to make significant improvements to the performance and maintainability of the Nexia codebase, while continuing to deliver new customer features.
