XML is rapidly becoming the standard platform for delivering e-Business information and integrating e-Business systems. XML developers desperately need mature software development processes and tools for developing effective applications. David Carlson fills the gap, showing exactly how to leverage the worldwide UML standard for modeling complex systems in advanced XML development. In Modeling XML Applications with UML, he presents the first comprehensive framework for modeling communications in any B2B software system. Carlson presents in-depth coverage of UML-based analysis, design, and modeling of XML content within e-Business environments. The book includes detailed coverage of using UML to support the creation of new XML-based B2B vocabularies and industry portals that reflect the requirements of several key stakeholder communities, including consumers, business analysts, web application specialists, system integration specialists, and content developers. Carlson presents several B2B use cases, and then decomposes them into scenarios illustrated with class diagrams, sequence diagrams, and activity diagrams showing how XML fits into an overall e-Business solution. Each chapter concludes with "steps for success" that distill UML's general principles into specific recommendations for action.
