Description

Beyond object-oriented analysis: the next breakthrough in software modeling.

  • Building models that enable greater reuse -- even in complex, rapidly changing environments.
  • Concepts, structure, key techniques, and practical application: includes extensive real-world examples.
  • Using metapattern to integrate your entire enterprise information architecture.
Metapattern is a revolutionary software analysis tool that makes possible models of unprecedented precision -- and breakthrough levels of software reuse. In this book, Pieter Wisse -- the creator of Metapattern -- offers the first comprehensive introduction to this new technique. Wisse begins with an informal case study illuminating the basics of metapattern, using it to model a simple event, and demonstrating its power. He offers a detailed introduction to the concepts underlying metapattern, including time-stamping and context orientation. Next, he compares metapattern with purely object-oriented approaches in solving a series of complex information modeling problems -- showing why it can often achieve richer, more useful results. Metapattern then walks step-by-step through modeling a full-scale financial accounting application, offering diverse IT organizations practical guidance for implementing the technique -- and for using it to enhance application integration, enterprise-wide. For all software architects, object-oriented developers, managers, and team leaders seeking to achieve greater reuse in their software systems.

Pieter Wisse is the author of the Dutch language book Aspecten en Fasen. A computer consultant based in The Netherlands, he holds a Ph.D. from the University of Twente.
