14+ Sequence Diagram Asynchronous Response. The sequence diagram is an interaction diagram of uml. Asynchronous messages don't require a response before the sender continues.
Displacement response for asynchronous motion by modal … from www.researchgate.net
Your response here line tells me that when b terminates you expect a to still be processing and, because you put it right at the end, to terminate traditionally sequence diagrams have had two jobs. They capture the interaction between objects in the context of a collaboration. Sequence diagrams can also be used to model synchronous and asynchronous messages.
However, in sequence diagrams you can model asynchronous messages, too.
14+ Sequence Diagram Asynchronous Response. An asynchronous message shows only a call from the sender. A sequence diagram simply depicts interaction between objects in a sequential order. They capture the interaction between objects in the context of a collaboration. Asynchronous calls are present in.
