In UML, an actor is a term used to describe a role played by a user or any system that will interact with the system's objects. A lifeline in a UML structure diagram represents each instance of interaction. Lifelines may start with an actor symbol or a designated rectangle form. This vertical dashed line depicts the consecutive events that affect an object during the charting process. It represents time passing by extending downward. See the components of the sequence diagram in UML below. To understand the UML sequence diagram, you need to be familiar with a sequence diagram's components and icons. Event diagrams and event scenarios are other names for sequence diagrams. Software engineers and business experts use these diagrams to comprehend a new system's specifications or describe an existing procedure. A sequence diagram, to put it simply, demonstrates how various components of a system interact with one another to complete a task.Īdditionally, since it illustrates the interactions between a group of items and the order in which they occur, a sequence diagram is a form of interaction diagram. They demonstrate the interactions that occur when a specific use case is executed and the order in which various system components interact to perform a function. What is A UML Sequence Diagramĭevelopers frequently use sequence diagrams to model item interactions in a single use case.
