Executable UML
open-in-new
<p>Executable UML (xtUML or xUML) is both a software development method and a highly abstract software language. It was described for the first time in 2002 in the book "Executable UML: A Foundation for Model-Driven Architecture". The language "combines a subset of the UML (<a href="/facts/Unified_Modeling_Language/3tlNS0tH">Unified Modeling Language</a>) graphical notation with executable semantics and timing rules." The Executable UML method is the successor to the <a href="/facts/Shlaer%25E2%2580%2593Mellor_method/ElYGvtSI">Shlaer–Mellor method</a>. </p><p>Executable UML models "can be run, <a href="/facts/Software_testing/VoXzG9Tb">tested</a>, debugged, and measured for performance.", and can be <a href="/facts/Compiler/WNfCDFJe">compiled</a> into a less abstract <a href="/facts/Programming_language/cWTYbgWa">programming language</a> to target a specific <a href="/facts/Implementation/IH1KXgP3">implementation</a>. Executable UML supports <a href="/facts/Model-driven_architecture/IY0daKp1">model-driven architecture</a> (MDA) through specification of platform-independent models, and the <a href="/facts/Compiler/WNfCDFJe">compilation</a> of the platform-independent models into <a href="/facts/Platform-specific_model/R04WWb8h">platform-specific models</a>. </p>
