The Unified Modeling Language (UML) is the standard modeling language for software and systems development. This statement alone is a pretty conclusive argument for making UML part of your software repertoire, however it leaves some questions unanswered. Why is UML unified? What can be modeled? How is UML a language? And, probably most importantly, why should you care?Systems design on any reasonably large scale is difficult. Anything from a simple desktop application to a full multi-tier enterprise scale system can be made up of hundredsand potentially thousandsof software and hardware components. How do you (and your team) keep track of which components are needed, what their jobs are, and how they meet your customers’ requirements? Furthermore, how do you share your design with your colleagues to ensure the pieces work together? There are just too many details that can be misinterpreted or forgotten when developing a complex system without some help. This is where modelingand of course UMLcomes in.
In systems design, you model for one important reason: to manage complexity. Modeling helps you see the forest for the trees, allowing you to focus on, capture, document, and communicate the important aspects of your system’s design.

Advances in UML and XML-Based Software Evolution reports recent advances in applications of two popularly used languages, UML and XML, in the field of software evolution. This book covers topics such as: visualizing legacy systems with UML, augmenting UML to support the design and evolution of user interfaces, migration of persistent object models using XML and much more. Advances in UML and XML-Based Software Evolution brings many specialists’ views into one comprehensive text for all academic researchers and industrial practitioners to learn more about these languages.
