Analysis Patterns discuss problems in analysis, and some models that can deal with them. Support patterns address problems in building computer systems around the analysis patterns. In Chapters 12 and 13 we consider the architecture for a client/server information system and how such a system can be layered to improve its maintainability. Chapter 14 looks at how conceptual models can be implemented, suggesting common patterns to turn analysis patterns into software.
Finally Chapter 15 is more abstract, examining modeling techniques themselves and how advanced modeling constructs can be viewed as patterns. This gives us a better basis for extending modeling methods to support particular needs.
