The sequence diagram given earlier represents an analysis-level sequence diagram as it may have been drawn by a business analyst. Subsequently, you finalize the choreography diagram to form a process by adding events, gateways, and sequence flows. Looking at the high level sequence diagram, the inbound and outbound interactions from FTM to external systems can be clearly seen. In this worked example I offer a cut-down use case specification that will drive the creation of the corresponding Sequence Diagram. Sequence diagrams emphasize the time ordering of messages. Hope this helps! UML sequence diagrams are used to show how objects interact in a given situation. Notice how an object lifeline has been used to represent the Insufficient Funds extension use case, which (when triggered) requires no further explanation at this level because there should be an entirely separate sequence diagram showing the behavior of the extension use case.

Having identified potential objects and operations (or ‘methods’) during the creation of our sequence diagrams, we are now in a position to model the logical relationships between those objects using the UML Class Diagram. The sequence diagram is arranged in the form of a strict top-to-bottom timeline of interactions – or message exchanges – between business entities or software objects. The objects involved in the operation are listed from left to right according to when they take part in the message sequence. This is a simple sequence diagram example for ATM. 21 The messages may be synchronous (shown with a solid arrowhead), asynchronous (shown with an open arrowhead), or flow (shown with a dashed arrow line). “: BankingMenu”) or as named object instances with their class types (e.g. Start: Represented by a green circle, there are several types, among them: If you see the code above in the images or recall the preceding image code, it is divided into three layers and three classes involved that are respectively part of each layer.
