UML (Unified Modeling Language)

A language developed and standardized by the OMG for the modeling of software and other systems. The UML defines identifiers for most terms important for the modeling and determines possible relations between these terms. The UML also provides graphic notations for these terms and for models of static structures and dynamic processes which can be formulated with these terms.
