To illustrate object interactions in information systems, use a UML sequence diagram template. Creating a sequence diagram will help you understand how the various sections of a system can collaborate to develop flawless functionalities and improve the overall customer experience. Sequence diagrams are frequently used in software engineering to describe the interactions of objects within a system. They show how different parts of the system interact with one another when performing a function, and they emphasize the order in which these interactions must occur. Sequence diagrams use a vertical axis to represent time and a horizontal axis to represent objects.
