Unified Modeling Language

UML diagram overview, Class diagram, Use-Case diagramm, State diagramm, Sequenz diagramm, Aktivity diagramm (in German).

Unified Modeling Language (UML) is a standardized visual specification language for object modeling in the field of software engineering.

Overview[edytuj]

Unified Modeling Language is a general-purpose modeling language that includes a graphical notation used to create an abstract model of a system, referred to as a UML model. It consists of:

Structure diagrams: emphasize what things must be in the system being modeled
Behavior diagrams: emphasize what must happen in the system being modeled
Interaction diagrams: a subset of behavior diagrams, emphasize the flow of control and data among the things in the system being modeled.

Unified Modeling Language is officially defined at the w:Object Management Group (OMG) by the w:UML metamodel, a w:Meta-Object Facility metamodel (MOF). Like other Meta-Object Facility-based specifications, Unified Modeling Language has allowed software developers to concentrate more on design and architecture.

Structure diagrams[edytuj]

Class diagram[edytuj]

A class diagram describes the structure of a system by showing the system's classes, their attributes, and the relationships between the classes. See Category:Class diagrams

Component diagram[edytuj]

A component diagram in the Unified Modeling Language depicts how a software system is split up into components and shows the dependencies among these components. See Category:Component diagrams

Composite structure diagram[edytuj]

Composite structure diagram is describes the internal structure of a class and the collaborations that this structure makes possible. See Category:Composite structure diagrams

Deployment diagram[edytuj]

A deployment diagram serves to model the hardware used in system implementations, the components deployed on the hardware, and the associations between those components.. See Category:Deployment diagrams

Object diagram[edytuj]

An object diagram shows a complete or partial view of the structure of a modeled system at a specific time. See Category:Object diagrams

Package diagram[edytuj]

A package diagram depicts how a system is split up into logical groupings by showing the dependencies among these groupings. See Category:Package diagrams

Behavior diagrams[edytuj]

Activity diagrams[edytuj]

An activity diagram In UML represents the business and operational step-by-step workflows of components in a system. An activity diagram shows the overall flow of control. See Category:UML Activity diagrams

State diagram[edytuj]

A state diagram in UML is a standardized notation to describe many systems, from computer programs to business processes. See Category:UML State diagrams

Use case diagram[edytuj]

A Use Case diagram in Unified Modeling Language shows the functionality provided by a system in terms of actors, their goals represented as use cases, and any dependencies between those use cases. See Category:Use Case diagrams

Interaction diagrams[edytuj]

Communication diagram[edytuj]

A Communication diagram models the interactions between objects or parts in terms of sequenced messages. They represent a combination of information taken from Class, Sequence, and Use Case Diagrams describing both the static structure and dynamic behavior of a system. See Category:UML Communication diagrams

Interaction overview diagram[edytuj]

An interaction overview diagram is a form of activity diagram in which the nodes represent interaction diagrams. See Category:Interaction overview diagrams
