Introduction

Wouldn't it be great to never rewrite code? To always face new challenges rather than solve the same problems over and over? To always solve new and interesting problems instead of rehashing old ones? If you remember how you solved a problem before, reuse that solution. Don't reinvent the wheel!

Software patterns help you avoid reinventing the wheel, in that they help you avoid reinventing the solution to a software problem that someone else has already solved.

Patterns have been around in the software community since at least the early 1990s. Software pattern authors have been writing patterns that document their proven solutions in the hope that you — the reader — will benefit from their experience.

In particular, many people are collecting and publishing patterns that structure software architecture — the underlying structure of the software. The goal of architectural patterns is to speed your development; allow you to move forward, knowing that a particular architecture will help rather than hinder you; and ultimately give you the time you need to solve new and interesting problems.

Pattern-Oriented Software Architecture For Dummies is written to help you understand the basics of software architecture. It also helps you understand software patterns. The book brings these two concepts together and presents eight software architectures that you can use in your next software design project. It also gives you some design patterns, tips, and resources where you can ...
