Open the UML model diagram that contains the UML element for which you want to create an activity diagram. The flow of control is triggered by the completion of actions (or activities) within the system. That does not necessarily mean that the action cannot be subdivided in the real world, but in this diagram will not be refined any further: The action can possess input and output information The output of one action can be the input of a subsequent action within an activity. Activity diagrams can be developed in various degrees of detail. They can be refined step by step. A name can be attached to an edge (close to the arrow). Add an Action shape for each action or activity state you want to represent. After the event is accepted, the flow that comes from this action (and is defined in the activity diagram) is executed. Do you remember anything at all from your computer science class? Each partition is set apart from its neighboring partition by a horizontal or vertical continuous line; from this stems the term swim lanes. Psst! Use the complex transition shapes, Transition (Fork) or Transition (Join), to represent the forking of one action state into multiple parallel states, or the synchronization of multiple action states into one state. An activity can have more than one initial node; in this case several flows start at the beginning of an activity: It is also possible that an activity has no initial node, but is initiated by an event (action: accepting an event). Did I mention that we're offering The activity diagram in Figure 3.18 is divided into two partitions: passenger (1) and passenger services (2). In the dialog box, select either Metric Units or US Units. Otherwise (5), the passenger cannot fly and the task of passenger services is completed. Work with state shapes in UML statechart and activity diagrams, Work with transition shapes in UML statechart and activity diagrams. Sending a signal means that a signal is being sent to an accepting activity: The accepting activity accepts the signal with the action accepting an event and can react accordingly, meaning according to the flow that originates from this node in the activity diagram. You should see the Shapes window next to the diagram.

After 3 years of work, we've finally released a new ebook on design patterns! activity diagram fork join handbook handbooks software Point to New, and then click Activity Diagram. Drag an Action State or State shape onto the drawing page for each action or activity state you want to represent. For the consolidation of two or more parallel flows we also use a synchronization bar, which is depicted as a thick horizontal or vertical line: During consolidation synchronization takes place, meaning the flow proceeds only after all incoming flows have reached the consolidation point. In our context, however, it is not important to describe this step in detail. Double-click the Control Flow shape to add a transition string, including an event, guard condition, action expression, and more. Accepting events is an important element for business processes in activity diagrams: Many business processes are initiated by events, for example, processing an order by the receipt of an order, or delivery by the receipt of a payment. The execution of an activity can contain parallel flows.

Double-click any shape to open its UML Properties dialog box where you can add a name, transition string, guard condition, deferred events, and other properties.

A flow final node terminates a flow. Calling, in itself, is an action; the outcome of the call is another activity: In this way, activities can be nested within each other and can be represented with different levels of detail. The activity final node indicates that an activity is completed. Use the Fork node to represent the forking of one action state into multiple parallel states. diagram activity flow object control uml2 uml ignore following name stack Note:If the tree view is not visible, on the UML menu, point to View, and then click Model Explorer. Because it is possible to explicitly describe parallel events, the activity diagram is well suited for the illustration of business processes, since business processes rarely occur in a linear manner and often exhibit parallelisms. On the View tab, make sure the check box next to Connection Points is selected. Use the Join node to represent the synchronization of multiple action states into one state. Search for UML Activity or scroll down in the Gallery to the UML Activity row. Use an activity diagram to describe how several activities are coordinated to provide a service or other end result. At the second cross bar (11) the simultaneously processed flows (9 and 10) are merged, meaning that only when the passenger is on the plane (10) and the luggage has been loaded onto the plane (9), does the control flow continue below the cross bar (11). ): Elements are connected by so-called activity edges and form the control flow, which can also be casually called flow. If you want to replace transition strings with signal icons, use the Signal Send and Signal Receipt shapes to represent the signals. You start reading at the initial node, or in Figure 3.17 with the acceptance of the event passenger arrive at check-in (1), and continue along the arrows of the control flow (2). This option makes connection points appear when you start connecting shapes. Fundamental elements of the activity are actions and control elements (decision, division, merge, initiation, end,etc. A UML activity diagram inVisio looks like a flow chart. Drag State, Action State, Object In State and Signal Receipt or Signal Send shapes into the areas defined by the swimlanes and connect them using Control Flow and Object Flow shapes. Use the Initial State and Final State shapes to represent initial and final pseudo states. The individual elements of an activity diagram can be divided into individual areas or partitions. Activity diagrams can show how the events in a use case relate to one another, or how a collection of use cases coordinate to represent a business workflow. In our context, an activity represents a business process (Figure 3.16). All arrows that come from this bar (7) symbolize flows that are processed simultaneously. At a definite point in time, this action starts a flow in the activity diagram. The workspace displays 'Activity' as a watermark. A decision node has one input and two or more outputs: Each output has a condition attached to it, which is written in brackets. The diamond below represents a conditional branch point or decision node. Each partition receives a name. In the tree view, right-click the icon for the package, subsystem, class, operation, or use case in which you want to create an activity diagram. For more information, see Work with transition shapes in UML statechart and activity diagrams. Glue the Control Flow shape endpoint (with an arrowhead) to a connection point on the destination Action State or State shape. Specific actions are calling other actions, receiving an event, and sending signals. Near the upper right corner of the page, select More templates. Drag the side selection handles on the swimlane shapes to make the lanes the size you want. Glue the Control Flow shape endpoint (without the arrowhead) to a connection point on the source Action State or State shape. In the external view, activity diagrams, just like use case diagrams, exclusively represent business processes and activities from the outside perspective. Or if you have a file open already, click File > New. Various criteria can lead to the creation of these partitions: organization entities, cost centers, locations, etc: Individual steps of an activity will be assigned to these partitions. To do that: Drag a Swimlane shape onto the drawing page. Start with a blank UML activity template or a UML activity starter diagram. A border can surround the activity, meaning the entire activity diagram. ", Generalization, Specialization, and Inheritance, Constructing Diagrams in the Process View, Transforming Data from the IT System to the Message "passenger list", Transformation of UML Messages into Various Standard Formats, Contact An activity diagram can have more than one exit in the form of activity final nodes: If several parallel flows are present within an activity, all flows are stopped at the time the activity final node is reached. If your admin has turned on "self-service purchasing," you can buy a license for Visio yourself. Partitions can be arranged in a two-dimensional manner; in this case the activity diagram is divided into individual cells like a grid. For the branching of flows in two or more parallel flows we use a synchronization bar, which is depicted as a thick horizontal or vertical line: Branching allows parallel flows within activities. Revise your memories with our new An hourglass symbol can be used to represent the acceptance of a time event: A typical example of a time event is triggering reminders after the deadline for payment has passed. This can be seen at the black dot with borderthe activity final node. If you want to indicate responsibility in the activity diagram, drag a Swimlane shape onto the page for each class, person, or organizational unit you want to represent. While the luggage is being loaded onto the airplane (9) the passenger is boarding the airplane (10). Hooray! Alternative Classes with Different Interfaces, Change Unidirectional Association to Bidirectional, Change Bidirectional Association to Unidirectional, Replace Magic Number with Symbolic Constant, Consolidate Duplicate Conditional Fragments, Replace Nested Conditional with Guard Clauses, Sequence Diagrams for Scenarios of Business Use Cases, The User View or "I don't care how it works, as long as it works. In our example, one more action (12) and subsequent to that the final state (13) follow, meaning that after the passenger is on the plane (10) and the luggage has been loaded onto the plane (9), the airplane can taxi toward the runway (12). The diamond below has several inputs and only one output: Its purpose is the merging of flows. You can now insert swimlanes and build the activity control in the diagram. #toc{position:sticky;top:40px;list-style-type:none;margin:0;padding:0 10px}.chap{clear:both}#toc ul{list-style-type:none;max-height:87vh;overflow-y:auto;background:#f6f8fa;border-width:2px;border-style:groove;border-radius:3px;border-color:#e1e4e8;margin:0;padding:0}@media screen and (min-height:450px){#toc ul{max-height:89.5vh}}@media screen and (min-height:550px){#toc ul{max-height:91.5vh}}@media screen and (min-height:700px){#toc ul{max-height:93.5vh}}@media screen and (min-height:900px){#toc ul{max-height:94.5vh}}#toc li{margin:5px 5px 5px 10px;padding:0}@media screen and (max-width:1500px){#toctd{display:none}#toc{display:none}}, Switch and case [switch, case, endswitch], Conditional with stop on an action [kill, detach], Parallel processing [fork, fork again, end fork, end merge], SDL (Specification and Description Language). This action waits for an event to occur. This is depicted in more detail in another activity diagram as is indicated by the fork in the action symbol: If you follow the control flow, next you will come to a conditional branch or decision node (4): if the check-in is OK the next step along the control flow can follow. sexy discounts right now? If you want to indicate responsibility in the activity diagram, drag a Swimlane shape onto the page for each class, person, or organizational unit you want to represent. Double-click each label on the shape to change the default name. Contrary to use case diagrams, in activity diagrams it is obvious whether actors can perform business use cases together or independently from one another.

Use a Decision shape with guard conditions to indicate a possible transition from an action state. Use the Initial node and Final node shapes to represent initial and final pseudo states. Note:Creating and editing UML diagramson Visio for the web requires a Visio Plan 1 or Visio Plan 2 license, which is purchased separately from Microsoft 365. Select Create on the one you want to use. You can now insert swimlanes and build the activity control flow in the diagram. The initial node is the starting point of an activity. Double-click the shape to add a name and other property values. Purists of the object-oriented approach probably dislike this fact. The inputs are not synchronized; if a flow reaches such a node it proceeds at the output without waiting for the arrival of other flows. Activity diagrams allow you to think functionally. We, on the other hand, regard this fact as a great advantage, since users of object-oriented methods, as well as users of functional thinking patterns, find a common and familiar display format, which is a significant aid for business-process modeling. Refining diagrams does not mean describing process details that are performed within the business system, which often leads to an unnoticed shift to the internal view (Figure 3.15): An activity diagram illustrates one individual activity. book on Computer Science. For more information, contact your Microsoft 365 admin.

Join has two or more inputs and one output. Drag the side selection handles on the Swimlane shapes to make the lanes the size you want. Repeat steps a and b until you've added all the partitions or organizational units you need.

If you dont see it, go to View > Task Panes and make sure that Shapes is selected.

For more details, see Self-service purchase FAQ. If a condition is met, the flow proceeds along the appropriate output. In the external view, we use activity diagrams for the description of those business processes that describe the functionality of the business system. All other actions are located in the partition (swim lane) of passenger services (2) and are carried out by passenger services. You can see here that the last action airplane taxis toward runway (12) is only defined as a single action, even though this process is very complex and could be described in many other activity diagrams. If you want to represent a flow in response to external events instead, use a state machine diagram. Quicksort, Graph traversal, Big'O and other stuff? Activity diagrams, which are related to program flow plans (flowcharts), are used to illustrate activities. A fork has one input and two or more outputs. An icon representing the diagram is added to the tree view.

The flow may be sequential, concurrent, or branched, indicated by shapes such as swimlanes, forks, and joins. Connect Control Flow shapes to State shapes to indicate the change from one state to another. If you still dont see it, click the Expand the Shapes window button on the left. After successful check-in (7) you come to a black cross bar. In an activity diagram, drag a Control Flow shape onto the drawing page. Edges, represented by arrows, connect the individual components of activity diagrams and illustrate the control flow of the activity: Within the control flow an incoming arrow starts a single step of an activity; after the step is completed the flow continues along the outgoing arrow. An action is an individual step within an activity, for example, a calculation step that is not deconstructed any further. From the Activity stencil, drag a Swimlane shape onto the drawing page.

An else output can be defined along which the flow can proceed if no other condition is met. With this symbol an activity can be called from within another activity. The subsequent action passenger checks in (3) means that at this point the activity passenger checks in is processed. The diagram opens.

Work with state shapes in UML statechart and activity diagrams. Start Visio. Unlike the activity final node, which ends an entire activity, reaching a flow final node has no effect on other parallel flows that are being processed within the activity at the same point in time: In this way, parallel flows can be terminated individually and selectively. Between point (8) and point (11) the flows are independent from one another. The passenger, for instance, carries out showing ticket at check-in counter (3), checking luggage (4), and paying fee (i). us. A blank page appears, and the UML Activity stencil becomes the top-most stencil.
