This article mainly shows you the "UML view and its role of example analysis", the content is easy to understand, well-organized, hope to help you solve your doubts, the following let the editor lead you to study and learn "UML view and its role of example analysis" of this article.

UML View and its function

UML (UnifiedModelingLanguage, Unified Modeling language) is a group of graphical expressions used to describe OOAD processes.

UML provides a set of comprehensive representations for communicating requirements, behavior, and architecture in object-oriented design.

UML drawing tools, EA and VSU2010

UML consists of nine different types of graphs:

Use case diagram: shows the external visual behavior of the system.

The use case diagram in the UML view describes the interaction between people outside the system and the system, as well as the response of the system. This type of diagram can be used to describe the functional requirements of the system.

Activity chart: a canyon Naxi description showing the behavior of the system.

The activity diagram in the UML view describes the detailed behavior within a single functional requirement, including basic scenarios and some optional scenarios.

Component diagram: shows the architecture of the system.

The component diagram in the UML view describes the system's deployable units (executables, components, data stores, and other content) as well as some excuses that the deployable units interact through these interfaces, which can be used to study the architecture of the system.

Sequence diagram: shows the interaction of objects over time.

The sequence diagram in the UML view describes the path of a functional requirement or the detailed behavior of relative time within a scenario, which can be used to understand the flow of messages between system elements.

Collaboration diagram: shows the interaction of objects and emphasizes the relationship between objects. (can't find it in UML2.0)

Class diagram: shows the definition and relationships of the class.

The class diagram in the UML view describes the classes and interfaces in the system design and the relationship between them. This diagram can be used to define an internal, object-oriented code structure.

State diagram: shows the state change of the response time.

The state diagram in the UML view describes how the system changes state to correspond to internal and external events, ensuring that each event is handled appropriately.

Deployment diagram: shows the physical architecture of the system.

The deployment diagram in the UML view describes how the deployable units of the system (applications, components, data storage, etc.) are assigned to different nodes and how these nodes communicate with each other for system mapping and load research.

Package diagram: shows the hierarchical structure of the design.

The package diagram in the UML view describes how the relevant elements of the design are grouped together and the relationship between them.

The above is all the content of the article "sample Analysis of UML View and its role". Thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
