UML

UML is a collection of diagrams used in software engineering to graphically represent systems, their components, and the relationships between them. UML was standardized by the Object Management Group (OMG) in 1997 and has since become a widely used modeling language.

UML is useful in many aspects of software development, including visualization, documentation, design, and communication with stakeholders. The language includes various types of diagrams such as use case diagrams, class diagrams, and sequence diagrams, which can be used to model different aspects of a system.

Use case diagrams show the interactions between a system and its users or external systems. Class diagrams depict the structure of a system by modeling its classes and their relationships. Sequence diagrams portray the interactions between objects in a system over time.

UML provides a standard and widely recognized notation for modeling complex systems. By using UML, software developers can better understand, communicate, and implement systems that meet the needs of their users.
