A conditional node or a decisional node is one where there are multiple options available. It generally visualizes the structure and an organization of a system. Starting State. So activity depicts what action is going to take place in the process. Example: There’s one ice cream shop. Component diagrams are often drawn to help model implementation details and double-check that every aspect of the system's required functions is covered by planned development. Activity diagrams are graphical representations of workflows of stepwise activities and actions with support for choice, iteration and concurrency. It describes how various components together make a single, fully functional system. Activity diagrams give focus to the workflow, while sequence diagrams give focus to the handling of business entities. It is different from other programming languages such as C, C++, Java.It helps to build a pictorial representation of the … The system invokeseach of these callbacks as an activity enters a new state.Figure 1 presents a visual representation of this paradigm.As the user begins to leave the activity, the system calls methodsto dismantle the activity. Activity Diagrams start from this step. This is the last stage of the UML activity diagram. In the Unified Modeling Language, activity diagrams are intended to model both computational and organizational processes (i.e., workflows), as well as the data flows intersecting with the related activities. A similar reuse established using relationships, will be apparent in the other UML diagrams as well. Activity Diagrams start from this step. In activity diagrams one single activity is depicted as shown in Figure 5.6. It is a behavior that is divided into one or more actions. For the purpose of UML 2.0, the term "component" refers to a module of classes that represent independent systems or subsystems with the ability to interface with the rest of the system.
