Now, a book to help you master UML 2.0 visual modeling -- with IBM Rational Software Architect

book cover Using IBM Rational Software Architect, you can unify all aspects of software design and development. It allows you to exploit new modeling language technology to architect systems more effectively and develop them more productively.

Now, two of IBM's leading modeling experts have written the definitive, start-to-finish guide to UML 2-based visual modeling with Rational Software Architect. You'll learn hands-on, using a simplified case study that's already helped thousands of professionals master analysis, design, and implementation with IBM Rational technologies.

Renowned UML expert Terry Quatrani and J2EE/SOA evangelist Jim Palistrant walk you through visualizing all facets of system architecture at every stage of the project lifecycle. Whether you're an architect, developer, or project manager, you'll discover how to leverage IBM Rational's latest innovations to optimize any project.

Coverage includes

Making the most of model-driven development with Rational Software Architect's integrated design and development tools
Understanding visual modeling: goals, techniques, language, and processes
Beginning any visual modeling project: sound principles and best practices
Capturing and documenting functional requirements with use case models
Creating analysis models that begin to reveal your optimal system implementation
Building design models that abstract your implementation model and source code
Using implementation models to represent your system's physical composition, from subsystems to executables and data
Transforming these models to actual running code

"Terry's style is always direct, approachable, and pragmatic. Abstraction is hard, and visualizing abstractions is as well, but here she'll guide you in doing both using Rational Software Architect."
-- From the Foreword by Grady Booch, IBM Fellow
