Guide To The Reader

“Cheshire-Puss will you tell me, please, which way I ought to go from here?”

“That depends a good deal on where you want to get to,” said the Cat.

“I don’t much care where—,” said Alice.

This book is structured so you can read it cover-to-cover. If you know where you want to get to, however, you may want to choose your own route through the book. In this case, the following hints can help you decide which topics to focus upon and the order in which to read them.

Introduction to Patterns

If this book is your initial exposure to patterns, we suggest you first read the introduction to patterns in [POSA1] and [GoF95], which explore the concepts and terminology related to patterns for software architectures and designs. In particular, all the patterns presented in this book build upon the conceptual foundation for patterns specified in [POSA1]:

• The definition of patterns for software architectures
• The categorization of these patterns into architectural patterns, design patterns, and idioms¹ and
• The pattern description format

Moreover, the implementations of many patterns in this book are enhanced by using patterns from [POSA1] and [GoF95]. To guide the application of the patterns in production software development projects we therefore ...
