Exception handling in UML Sequence Diagram UML provides neither notation to model exception handling in sequence diagrams nor any reasoning why it is absent. Some clumsy approaches to model try-catch blocks are by utilizing combined fragments - alt (alternatives) and breaks, while adding stereotypes for reply messages representing thrown exceptions. There are several proposed notations for exception handling.

Sequence Diagram Tutorial - Complete Guide with Examples Sequence diagrams, commonly used by developers, model the interactions between objects in a single use case. They illustrate how the different parts of a system interact with each other to carry out a function, and the order in which the interactions occur when a particular use case is executed. In simpler words, a sequence diagram shows different parts of a system work in a ‘sequence’ to get something done. UML sequence diagram - how to represent async response ... The term async doesn't really apply at this level. Async describes an event (message or otherwise) that happens independent of the main flow of the program (here, A or B). It is an adjective that describes implementation detail and timing of external events relative to the internal threading design of either a client or a server, and evokes strategies to handle such events as the main program ... Service Request System - an overview | ScienceDirect Topics In this chapter, an alternative approach to representing behavior is introduced; it uses sequence diagrams to represent the interaction between structural elements of a block as a sequence of message exchanges. The interaction can be between the system and its environment or between the components of a system at any level of a system hierarchy.

If you take the UML standard by the letter, a sequence diagram is an interaction diagram (clause 17.8 of the specs), and therefore represents interactions between elements of an enclosing classifier (clause 17.2.3.1), which means a class, a component or the system as a whole.. An actor does not belong to the system: it should therefore not appear as a lifeline.
