Executable UML is for software professionals who want to apply object-oriented analysis and modeling techniques to real-world UML projects. In this book, Leon Starr presents the skills and techniques needed to build useful class models for creating precise, executable software specifications that generate target code in multiple languages and for multiple platforms. Leon, who wrote the definitive guide to Shlaer-Mellor modeling, emphasizes the practical use of executable UML modeling, presenting extensive examples from real-time embedded and scientific applications. Using the materials in his How to Build Shlaer-Mellor Object Models as a starting point, Leon presents an entirely new introduction to Executable UML, expresses all diagrams in Executable UML notation, and adds advanced new object modeling techniques. Coverage include: classes; attributes; associations and relationships; binary associations; association classes; specialization-generalization relationships; model constraints and descriptions; and reflexive, network, linear, and tree patterns for effective object modeling.
