UML in Practice

• Offers comprehensive coverage of all major modeling viewpoints
• Provides details of collaboration and class diagrams for filling in the design-level models

"UML in Practice" beschreibt auf der Basis konkreter Beispiele, Problemstellungen und detaillierten Lösungen die drei Hauptaspekte (funktional, statisch und dynamisch) bei der Modellierung von Softwaresystemen.

Das Buch basiert auf einem ganz neuen thematischen Ansatz und demonstriert dem Leser anschaulich, wie ein Modellierungsexperte mögliche Lösungen in der Praxis analysiert und bewertet.

Behandelt umfassend alle wichtigen Modellierungsaspekte.

"UML in Practice" - ein praktischer und fundierter Leitfaden über die Anwendung von UML in der täglichen Praxis. Hier werden Softwareentwickler mit jedem Aspekt des Modellierungsprozesses vertraut gemacht.

Mit umfangreichen Arbeitsbeispielen und Lösungen.

Pascal Roques is a senior trainer and consultant running courses on UML. He has led training in modeling techniques and tools at Verilog (now Telelogic) and since 1995 at Valtech. UML is the de facto industry standard modeling language for specifying, visualising, constructing and documenting aspects of the design of software systems. To use UML effectively is to move beyond the theoretical presentation of language notation and to understand how to use it to communicate both the modeling problems and their solutions.

This book is a practical discussion of a wide range of UML based techniques, introduced within the context of real-life examples and solutions. Pascal Roques is involved in day-to-day software development, and the emphasis he places on real-life projects is unique in demonstrating how a modeling expert thinks and assesses possible solutions.

UML in Practice provides comprehensive coverage of the three main modelling viewpoints at the analysis level – functional, static and dynamic – through examples and exercises. A final section provides the detail of collaboration and class diagrams to fill in the design level models. This book is fully compliant with UML 2.0 and is a refreshing and accessible guide to the art of modeling software systems with UML.
