Part IV: Putting It All Together: Thinking in Patterns

Part Overview

In this part, I propose an approach to designing object-oriented systems based on patterns. I have proven this approach in my own design practice. I apply this approach to the CAD/CAM problem that we have been examining since Chapter 3, “A Problem That Cries Out for Flexible Code.”

This approach first tries to understand the context in which objects show up.

Chapter	Discusses These Topics
11	A discussion of Christopher Alexander's ideas and how experts use these ideas to design.
12	Application of this approach to solve the CAD/CAM problem first presented in Chapter 3. A comparison of this solution with the solution I developed in Chapter 4.
13	A summary of what I have discussed about object-orientation and design patterns. The concepts here are what I call pattern-oriented design.
