To comprehend what a Sequence Diagram is, you must first comprehend the purpose of the Unified Modeling Language, or UML. UML is a modeling toolset that may be used to create and notate a variety of diagrams, such as behavior diagrams, interaction diagrams, and structure diagrams.
A Sequence Diagram UML is a sort of interaction diagram that shows how a group of items interacts and in what order. Software engineers and business experts use these diagrams to understand the requirements for a new system or to describe an existing process. Event diagrams and event scenarios are other names for diagrams.
