Interface Oriented Design focuses on an important, but often neglected, aspect of object-oriented design. You'll learn by pragmatic example how to create effective designs composed of interfaces to objects, components and services. You'll see techniques for breaking down solutions into interfaces and then determining appropriate implementation of those interfaces to create a well structured, robust, working program.
