Sequence diagrams are a type of Universal Modeling Language (UML) diagram. They’re used to show how objects in a system work together over time. A sequence diagram helps the designer of a system visualize and understand the order in which these interactions occur. This can make it easier to identify potential problems and optimize how everything works.
Let’s quickly summarize the basic elements in a sequence diagram.
The sequence diagram moves from top to bottom to show the sequence of events in the system. The objects included are shown at the top and bottom of the diagram as labeled rectangles with a lifeline descending the full length of the diagram. The interactions between objects are shown as horizontal arrows that go left or right. These represent messages passing between the objects.
