This Activity Diagram Example is another crucial behavioral diagram in a UML diagram for describing the dynamic aspects of a system. An activity diagram is essentially a more advanced version of a flow chart that depicts the flow of one activity to the next. Activity Diagrams explain how activities are coordinated to provide a service at various levels of abstraction. Typically, an event must be accomplished by some operations, particularly when the process is intended to achieve several different things that necessitate coordination or how the events in a single use case relate to one another, particularly in use cases where activities may overlap and necessitate coordination.
