This UML Sequence Diagram of the Report Generation System depicts how a user configures the report designer and requests the generation of a report. The database server generates the information, which is then returned to the user. The info can be saved in CSV format by the user. Because they specifically focus on lifelines or processes and objects that live concurrently and the messages exchanged among them to perform a function before the lifeline ends, sequence diagrams are a popular dynamic modeling solution in UML. UML is a modeling toolkit that helps create and notate many different types of diagrams, such as behavior diagrams, interaction diagrams, and structure diagrams.
