Introduced in 1997, the Unified Modeling Language (UML) has rapidly been accepted throughout the software industry as the standard graphical language for specifying, constructing, visualizing, and documenting software-intensive systems. The UML provides anyone involved in the production, deployment, and maintenance of software with a standard notation for expressing a system's blueprint. The UML covers conceptual things, such as business processes and system functions, as well as concrete things, such as programming-language classes, database schemas, and reusable software components. In The Unified Modeling Language User Guide, the original developers of the UML-Grady Booch, James Rumbaugh, and Ivar Jacobson-provide a tutorial to the core aspects of the language in a two-color format designed to facilitate learning. Starting with a conceptual model of the UML, the book progressively applies the UML to a series of increasingly complex modeling problems across a variety of application domains. This example-driven approach helps readers quickly understand and apply the UML. For more advanced developers, the book includes a learning track focused on applying the UML to advanced modeling problems.With The Unified Modeling Language User Guide, readers will:understand what the UML is, what it is not, and why it is relevant to the development of software-intensive systemsmaster the vocabulary, rules, and idioms of the UML in order to "speak" the language effectivelylearn how to apply the UML to a number of common modeling problemssee illustrations of the UML's use interspersed with use cases for specific UML featuresgain insight into the UML from the original creators of the UML
