Either model generic interactions (showing all possible paths through the interaction) or specific instances of a interaction (showing just one path through the interaction).
Model the interaction between objects within a collaboration that realizes an operation.Model the interaction between object instances within a collaboration that realizes a use case.Model high-level interaction between active objects in a system.A comment carries no semantic force, but may contain information that is useful to a modeler. NoteĪ note (comment) gives the ability to attach various remarks to elements. Duration MessageĪ duration message defines a particular communication between lifelines of an interaction, which shows the distance between two time instants for a message invocation. Destroy MessageĪ destroy message defines a particular communication between lifelines of an interaction, which represents the request of destroying the lifecycle of target lifeline. Create MessageĪ create message defines a particular communication between lifelines of an interaction, which represents the instantiation of (target) lifeline. It's target points to an activation on top of the activation where the message was invoked from. Recursive MessageĪ recursive message defines a particular communication between lifelines of an interaction, which represents the invocation of message of the same lifeline. Self MessageĪ self message defines a particular communication between lifelines of an interaction, which represents the invocation of message of the same lifeline.
Return MessageĪ return message defines a particular communication between lifelines of an interaction, which represents the pass of information back to the caller of a corresponded former message.

A sequence diagram describes an interaction among a set of objects participated in a collaboration (or scenario), arranged in a chronological order it shows the objects participating in the interaction by their "lifelines" and the messages that they send to each other.
