| UML is the acronym
for Unified Modeling Language. It is a standard format for documenting
the requirements and design of an IT system. UML is often used
by a business analyst and
a software architect to define the functionality of a system and
the specifics of how it will be built.
|
UML defines nine types
of diagrams. Some of these diagrams give specific insight into
business processes. For
example Use Case diagrams are closely tied to processes because
they model the functionality of the system from the perspective
of an actor, or user. Similarly state chart diagrams describe
the dynamic behavior of a system in response to external stimuli.
In addition, activity diagrams illustrate the dynamic nature
of a system by modeling the flow of control from activity to activity.
Typically, activity diagrams are used to model workflow,
business processes and internal operations.
