What is a uml dynamic model diagram?

Uml dynamic model diagram includes state diagram, activity diagram, sequence diagram, collaboration diagram, etc.

1, state diagram

State diagrams are used to describe the states of objects and the transitions between states. It can display various states of an object in its life cycle, as well as the transition conditions and paths between states.

2. Activity diagram

Activity diagram is used to describe the behavior and operation flow of a system or an object. It can display the execution process of an operation or a series of operations, including the sequence, conditions and branches of activities.

3. Program table

Sequence diagram is used to describe the interaction and message passing between system objects. It can show the communication relationship between objects and the order of message delivery.

4. Collaboration diagram

Similar to sequence diagrams, collaboration diagrams are also used to describe the interaction and message passing between objects. But it focuses more on showing the structure and responsibility relationship between objects.

Characteristics of the model diagram:

1, intuitive

The architecture model represents the architecture design in the form of micro-entities. This form makes the conception of architectural design more in-depth and perfect, so as to be directly close to the real building. Because it shows the image of an intuitive entity in three-dimensional space, it is convenient for people to study the relationship between a building project and the environment in order to make feasible plans.

Step 2 show

Compared with other forms of expression, the physical authenticity and perfection of the architectural model are more obvious, and the image always runs through the architectural design and performance. The authenticity of the architectural model lies in that it is intuitively reflected in people's vision in a three-dimensional form. Even people who have no professional thinking and imagination in architecture can appreciate and comment on architecture directly.
