The Sequence Diagram is a visual representation of the sequence of steps that occur when two or more objects interact. It is used to illustrate the interactions between objects in a system and the order in which those interactions take place. The diagram consists of a series of boxes connected by arrows, with each
In software engineering, a sequence diagram shows process interactions arranged in time sequence. This diagram depicts the processes and objects involved and the sequence of messages exchanged as needed to carry out the functionality. Sequence diagrams are typically associated with use case realizations in the 4+1 architectural view model of the system under development. Sequence diagrams are sometimes called event diagrams or event scenarios.
