Unified Modeling Language (
UML) is a standardized general-purpose
modeling language in the field of
software engineering. The standard is managed, and was created by, the
Object Management Group.
UML includes a set of graphical notation techniques to create
visual models of software-intensive systems.
The Unified Modeling Language (UML) is used to specify, visualize, modify, construct and document the
artifacts of an
object-oriented software intensive system under development.
[1] UML offers a standard way to visualize a system's architectural
blueprints
UML combines best techniques from
data modeling (
entity relationship diagrams),
business modeling (work flows),
object modeling, and component modeling. It can be used with all processes, throughout the
software development life cycle, and across different implementation technologies.
[3] UML has synthesized the notations of the
Booch method, the
Object-modeling technique (OMT) and
Object-oriented software engineering (OOSE) by fusing them into a single, common and widely usable
modeling language. UML aims to be a standard modeling language which can model concurrent and
distributed systems. UML is a de facto
industry standard, and is evolving under the auspices of the
Object Management Group (OMG). OMG initially called for information on object-oriented methodologies that might create a rigorous software modeling language. Many industry leaders have responded in earnest to help create the UML standard.

UML models may be automatically transformed to other representations (e.g. Java) by means of
QVT-like transformation languages, supported by the
OMG. UML is
extensible, offering the following mechanisms for customization:
profiles and
stereotype. The
semantics of
extension by profiles have been improved with the UML 2.0 major revision.
