DEFINITION FOR UML

• "The Unified Modeling Language (UML) is a

graphical language for visualizing,

specifying, constructing, and documenting the

artifacts of a software-intensive system.

The UML offers a standard way to write a system's

blueprints, including conceptual

things such as business processes and system

functions as well as concrete things such

as programming language statements, database

schemas, and reusable software

components.“ • Courtesy- http://www.sparxsystems.com/uml-tutorial.html
