A sequence diagram is a type of interaction diagram. True or false?

Question

BlackTom AI · Accepted Answer

The question asks whether a sequence diagram is a type of interaction diagram, and asks for a true/false judgment.
First, note that in UML, interaction diagrams describe how objects and components interact to accomplish a behavior. These include sequence diagrams, communication (collaboration) diagrams, timing diagrams, and interaction overview diagrams. This means sequence diagrams are indeed classified under the umbrella of interaction diagrams.
Since the answer options are not provided in this instance, there are no alternative statements to evaluate, but we can still verify the core claim: a sequence diagram focuses on the time-ordered exchange of messages between lifelines, illustrating the sequence of interactions, which aligns with the definition of an interaction diagram rather than something like a class or component diagram.
If you were to contrast with other diagram types, you could point out that a class diagram shows static structure, not interactions, reinforcing that the sequence diagram belongs to the interaction family and not to non-interaction diagram categories.
In summary, the statement is true because sequence diagrams are indeed a type of interaction diagram in UML, designed to model the sequence of messages in a scenario.
