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. 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 diagrams.
PlantUML is an open-source tool allowing users to create diagrams from a plain text language. Besides various UML diagrams, PlantUML has support for various other software development related formats (such as Archimate, Block diagram, BPMN, C4, Computer network diagram, ERD, Gantt chart, Mind map, and WBD), as well as visualisation of JSON and YAML files.

A sample UML class and sequence diagram for the Facade design pattern. In this UML class diagram , the Client class doesn't access the subsystem classes directly. Instead, the Client works through a Facade class that implements a simple interface in terms of (by delegating to) the subsystem classes ( Class1 , Class2 , and Class3 ).
UMLsec is an extension to the Unified Modeling Language for integrating security related information in UML specifications. This information can be used for model-based security engineering. Most security information is added using stereotypes and covers many security properties including secure information flow, confidentiality, and access ...
UML ( Unified Modeling Language) is a modeling language used by software developers. [1] UML can be used to develop diagrams and provide users (programmers) with ready-to-use, expressive modeling examples. [note 1] Some UML tools generate program language code from UML. [2] UML can be used for modeling a system independent of a platform language.
A user interface model is a representation of how the end user (s) interact with a computer program or another device and also how the system responds. The modeling task is then to show all the " directly experienced aspects of a thing or device" [Trætteberg2002]. Modeling user interfaces is a well-established discipline in its own right.
