Software Composition Using Behavioral Models of Design Patterns

Abstract

Given a set of requirements structured as design problems, we can apply design patterns to solv e each problem individually. Much of the published literature on design patterns addresses this problem —pattern association; however, there is no systematic and practical way that shows how to integrate those individual solutions together. We propose a compositional model based on design patterns by abstracting their behavioral model using role modeling constructs. This approach describes how to transform a design pattern into a role model that can be used to assemble a software application. The role model captures the behavioral relationship between participant components in the design pattern. Our approach offers a complete practical design and implementation strategies, adapted from DCI (Data, Context, and Interaction) architecture. We demonstrate our technique by presenting a s i mple case study complete with design and implementation code. We also present a s i mple to follow process that provides guidelines of what to do and how to do it.
