Unified Modeling Language™ (UML®) is a visual language for specifying, constructing, and documenting the artifacts of systems.
Complex software designs difficult for you to describe textually can readily be conveyed through diagrams using UML. Modeling provides three key benefits:
Visualization
Complexity management
Clear communication
You can use UML with all processes throughout the development lifecycle and across different implementation technologies.
UML was approved by the Object Management Group™ (OMG™) (link resides outside of ibm.com) a standard in 1997. Over the past few years, there have been minor modifications made to the language. UML 2 was the first major revision to the language.
