uml interaction diagram

passed between the object classes that complete a behavior and those object classes. A sequence diagram is an interaction diagram that emphasizes the time order of messages. A sequence diagram describes the chronological order in which messages are sent between objects, and is used to represent the order of behavior i

Prefaceafter learning the UML time series diagram, we need to look at the UML collaboration diagram, because the two graphs are complementary. definitiondescribe the relationships between objects of mutual cooperation and only model the relationships between objects interacting with each other. compositionObjectat the

The interaction diagram is used to describe how objects interact in the system, that is, how a group of objects transmit messages. An interaction diagram consists of a group of objects and their relationships, including: What objects are required, what messages are sent between objects, what roles start a message, and

. It is possible to draw the behavior between objects in chronological order. in UML , a sequence diagram describes the interaction between objects in a system by a two-dimensional graph. Where the longitudinal axis represents time and the horizontal axis represents the object that participates in the interaction.

Several important grasp principles: 1. Controller mode 2. Creator mode (principle) 3. Information Expert mode (principle) 4.

The interaction diagram is used to describe how objects interact in the system, that is, how a group of objects transmit messages. Interaction is mainly used to describe the dynamic behavior of collaboration. When modeling interactions, it usually includes objects (each object assumes a specific role), messages (each message represents the communication activit

sequence diagram, a sequence receives and sends messages (also known as interactions). A model can be established by connecting the message and the Framework Element Boundary (see figure 2 ). For a sequence chart, the label of the chart starts with the text "sd. When you use a frame element to close a graph, the label of the graph must follow the format below: Graph type graph name.
