What does uml mean?

UML modeling technology is a modeling language, which refers to the use of model elements to build the model of the whole system. Model elements include classes in the system, the association between classes, and the cooperation of class instances to realize the dynamic behavior of the system.

UML provides various graphical visualizations to describe model elements. The same model element may appear in multiple diagrams corresponding to multiple graphic elements, and people can check the model from multiple views.

Extended data:

UML is a general graphic modeling language in object-oriented development, which is well defined, easy to express, powerful and universally applicable.

Object-oriented analysis shows better ability than other system analysis methods in strengthening the understanding of problem space and system tasks, improving communication between all parties, keeping consistent with requirements and supporting software reuse, and has become the mainstream system analysis method.

The emergence of UML not only unifies the methods such as Booch, OMT and OOSE, but also unifies the symbols used in object-oriented methods, and it was accepted by OMG as one of its standards shortly after it was put forward.

Thus, the situation that dozens of object-oriented modeling languages are independent of each other and have their own strengths has been changed, and the object-oriented analysis technology has achieved unprecedented development.

It has become an important tool for object analysis and design in modern software engineering environment and is considered as one of the important achievements of object-oriented technology.
