From the Author
The book that tells you how to combine EJB and COM+ with UMLWe wrote this book to help those of you who want to use UML to describe components built using technologies such as EJB and COM+. A technology-independent specification of a component is very useful in providing a more abstract view. UML, together with OCL, provides a mechanism for putting precision into the abstract specifications.
Other books provide an overview of UML, but this book explains specifically how to use UML to specify components. Most importantly, it also provides a simple step-by-step process for moving from requirements to component specifications.
From the Back Cover
Developers using component technologies such as COM+ and Enterprise JavaBeans need to be able to define and express specifications for their components. They can do so using the Unified Modeling Language (UML), whether or not the components are being implemented internally using object technology. However, they also need a simple process that ensures specifications relate correctly to requirements.
Although originally conceived as a notation for object-oriented modeling, UML has great potential for component-based systems. UML Components applies UML to the world of component architecture, demonstrating how it can be used to specify components, their interactions, and their integration into cohesive systems. This book shows readers which elements of UML apply to server-side component-based development and how to use them most effectively. Following a simple step-by-step process, the authors walk through requirements definition, component identification, component interaction, component specification, and provisioning and assembly. Throughout, the focus is on the specification of the external characteristics of components and their inter-dependencies, rather than on internal implementation. Numerous UML diagrams illustrate component specifications, and a detailed case study demonstrates important concepts and techniques.
System architects, designers, programmers, and testers interested in leveraging the advantages of UML will find this a concise, practical, and insightful guide. The authors address the two great challenges of designing and constructing enterprise-scale component-based software: finding a process that can support the construction of large component systems, and making the best use of the wide range of notations and techniques found in the UML.
