Embracing Common Design Patterns

In this session, Rob Bagby will discuss 3 common design patterns: 1) The Strategy Pattern, 2) The Factory Pattern and 3) The Repository Pattern. Rob will illustrate how the Strategy and Factory patterns can help your design adhere to the Single Responsibility Principle (The "S" in SOLID) and the Open-Closed Principle (The "O"). Rob will then discuss the popular Repository Pattern, discussing some of the differing views on this pattern such as whether generic repositories are evil or great and whether one should use this pattern at all (after all, don't most ORMs do this?).
