Elemental Design Patterns

4. Working with EDPs

Until now we’ve talked about Elemental Design Patterns (EDPs) using a number of metaphors, including building blocks, and comparisons to the periodic table of chemistry. Those metaphors and comparisons were selected because they are used in domains where composition of fundamental pieces into larger, more useful constructs is critical. This applies for us as well and leads to an assumption that EDPs can be joined into meaningful larger pieces. In Chapter 3, you were introduced to Pattern Instance Notation (PIN), and part of that discussion showed how PINboxes can be joined in a diagram, illustrating how multiple instances of design patterns such as EDPs can interact.

In this chapter, we put all of this information together ...
