27 Patterns at Work

In this tutorial we present in detail a part of a concrete real-world system and how it is designed with patterns: the representation of physical storage in a warehouse management system as well as the client interface to this subsystem. Step by step we will re-play the process of the system's construction. We discuss the design problems that occur, present the patterns that could help solve these problems, discuss design alternatives and show how we actually applied the patterns we selected. By this we will see how the design of the system slowly grows and evolves towards the final architecture. We will also see and discuss how patterns are applied in practice and how they help building high-quality software with predictable properties. The tutorial concludes with a summary of our experiences from several projects in which we applied patterns: what worked, what could be improved, and what did we learn.
