This landmark book provides a thorough overview of the Unified Process for software development‎,‎ with a practical focus on modeling using the Unified Modeling Language‎.‎ The Unified Process goes beyond mere object‎-oriented analysis and design to spell out a proven family of techniques that supports the complete software development life cycle‎.‎ The result is a component‎-based process that is use‎-case driven‎,‎ architecture‎-centric‎,‎ iterative‎,‎ and incremental‎.‎ The Unified Process takes full advantage of the industry‎-standard Unified Modeling Language‎.‎This book demonstrates how the notation and process complement one another‎,‎ using UML models to illustrate the new process in action‎.‎ The authors clearly describe the semantics and notation of the different higher‎-level constructs used in the models‎.‎ Constructs such as use cases‎,‎ actors‎,‎ subsystems‎,‎ classes‎,‎ interfaces‎,‎ active classes‎,‎ processes‎,‎ threads‎,‎ nodes‎,‎ and most relations are described in the context of a model‎.‎ Object technology practitioners and software engineers familiar with the authors‎'‎ past work will appreciate The Unified Software Development Process as a useful means of learning the current best practices in software development‎.‎
