10+ Sequence Diagram Optional Flow. What is an sequence diagram? In a uml sequence diagram, combined fragments let you show loops, branches, and other kinds of combined fragment.
The worker can choose to perform the tasks within the subprocess at any time, in any order, and repeating any number of times. A lifeline will usually have a rectangle containing its object name. In this video we demonstrate how to model and simulate loops, alternatives and optional path in sequence diagram using combined fragments.
Sequence diagram is the most common kind of interaction diagram , which focuses on the sequence diagram describes an interaction by focusing on the sequence of messages that are exchanged, along with their corresponding occurrence specifications on the lifelines.
10+ Sequence Diagram Optional Flow. (for example, modeling logical flow in uml 1.x was complicated and at times impossible. Sequence diagram is an interaction diagram that shows the objects participating in a particular interaction and the messages they exchange arranged in a time sequence. In a uml sequence diagram, combined fragments let you show loops, branches, and other kinds of combined fragment. A simple sequence diagram shows just optional.
