14+ Object In Sequence Diagram. Createmessage is a message type that signals a new instance of a lifeline. In sequence diagrams, the returned object type is indicated by an identifier in the text in each box, such as user:
It means the object diagram is closer to the actual system behavior. Sequence diagrams are a type of unified modeling language (uml) diagram that shows interactions over time. It depicts the objects and classes involved in the scenario and the sequence of messages exchanged between the objects needed to carry out the functionality of the scenario.
We could have simplified figure 3 by omitting the product object and its interactions with.

Actors, objects, lifelines, messages, and activation boxes. As you can guess from its name, the sequence diagram shows the order in which interactions take place.
