Glue the endpoint without an arrowhead to a connection point on the element that depends on the other element.ĭouble-click the dependency to add a name, stereotype, and other properties. Flow 1 1.1 action 1.2 action Flow 2 2.1 action 2.2 action Autonumber events in sequence diagram. Glue the endpoint with an arrowhead to a connection point on the element the other element depends on. When sequence is important then I use a numbering scheme like this. You would also represent with a lifeline each threaded object that interact with your shared object. So your object that is shared between the threads should appear once and only once in the diagram. Indicate a dependency relationship between UML elementsĭrag a Dependency shape from the UML Static Structure, UML Deployment, or UML Component stencil onto the drawing page and place it near the elements you want to relate. 22 In a sequence diagram, a lifeline represents an individual participant in the interaction. Use Dependency shapes to indicate the relationships between components or between one component and another component's interface. To change the type of shape that displays for an interface, right-click the Interface shape and click Show as Class-like Interface or Show as Lollipop Interface. Use this shape when you want to display a list of the interface operations. You can also represent an interface with a rectangular Interface shape that resembles a class. ![]() Glue the endpoint without the circle to a connection point on the class component, or other element.ĭouble-click the Interface shape to add a name, operations, and other property values. In a static structure, component, or deployment diagram, drag the lollipop Interface shape onto the drawing page. Where appropriate, drag an Interface shape onto the drawing page and glue the endpoint without the circle to a component shape.Īdd an interface to a class, component, or other elements Note: If the tree view isn't visible, point to View on the UML menu, and then click Model Explorer.ĭrag a Component shape onto the drawing page for each component you want to represent. To move the text independently of the shape, go back to the Text Block Tool. ![]() If you use the Pointer Tool to drag the text, the shape will also move. When you’re done, click the Pointer Tool buttonĪfter you switch back to the Pointer Tool button, the text keeps the same position relative to the shape. On the Home tab, in the Tools group, click the Text Block toolĬlick the connector that has text your want to rotate or move.ĭrag the text block to move it, or rotate it using the Rotation Handle Here’s how to do that:Ĭlick an empty area of the page to deselect anything that may be selected. Most likely you’ll need to rotate or move text on your connector lines. If you anticipate moving shapes a lot, consider making a dynamic connection instead of a point connection. Make dynamic connections instead of point connections Right-click the connector, and then click Set Connector Type. Simply stamp them to your page and connect the symbols. You'll notice that all the notations and symbols you need are docked to the left of your drawing area. For example, you can change from an Association to a Directed Association. Back to top Sequence Diagram Tutorial Start with one of SmartDraw's included sequence diagram templates. ![]() If you do not need all the text boxes, delete the ones you don’t need. When you’re done, four text boxes appear where you can add details. If needed, right-click the connector and select Show Multiplicity. In the user authentication process we describe, the messages show how a user enters information into the browser to gain access to the webpage and how the web browser will then cross-check credential to the designated application.If a connector is taking too many turns, right-click it, and then click Straight Connector. What information is passed from one object to another? The other set of components you must identify are the messages the objects will send. The objects, sometimes called actors, are the principal players that perform tasks and send messages.įor example, in a login sequence, two of the objects would be the potential visitor or user and the login page a visitor uses to interact with the platform they’re attempting to log into. The first necessary set of components are the objects. To accomplish these goals, you must first identify the components of your system that should be diagrammed. Map out a real or hypothetical scenario that has many different components. See how objects and components interact with each other in sequence to complete a process. Model how a complex procedure or system operates. You can accomplish several critical tasks with a sequence diagram.
