UML logo. The unified modeling language (UML) is a general-purpose visual modeling language that is intended to provide a standard way to visualize the design of a system. [1] UML provides a standard notation for many types of diagrams which can be roughly divided into three main groups: behavior diagrams, interaction diagrams, and structure ...
The UML graphical representation of a Realization is a hollow triangle shape on the interface end of the dashed line (or tree of lines) that connects it to one or more implementers. A plain arrow head is used on the interface end of the dashed line that connects it to its users.
UML state machines have the characteristics of both Mealy machines and Moore machines. They support actions that depend on both the state of the system and the triggering event , as in Mealy machines, as well as entry and exit actions , which are associated with states rather than transitions, as in Moore machines.
UML is a graphical language for visualizing, specifying, constructing, and documenting information about software-intensive systems. [3] UML gives a standard way to write a system model, covering conceptual ideas. [4] [note 2] With an understanding of modeling, the use and application of UML can make the software development process more efficient.
The Sequence diagram of UML Overview. In software engineering, a sequence diagram [1] shows process interactions arranged in time sequence. This diagram depicts the processes and objects involved and the sequence of messages exchanged as needed to carry out the functionality.
In Unified Modeling Language (UML), a component diagram [1] depicts how components are wired together to form larger components or software systems. They are used to illustrate the structure of arbitrarily complex systems.

While in UML 1.x, activity diagrams were a specialized form of state diagram, [6] in UML 2.x, the activity diagrams were reformalized to be based on Petri net-like semantics, increasing the scope of situations that can be modeled using activity diagrams. [7] These changes cause many UML 1.x activity diagrams to be interpreted differently in UML ...
