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. 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. (.) Thanks, StarUML Team This was the answer about the same question in this forum. To place some text in the largest rectangle, I would assume, that (0.5, -0.5) would do the job. Somehow the coordinates of the rectangles are not in line with the coordinates of the nodes. At this time, we recommend to use 'Text' or 'Note' annotation. The code below draws three nested rectangles. To accomplish these goals, you must first identify the components of your system that should be diagrammed. Typically just show the guards of the control flows connected to the decision node, instead of showing the name of decision node. Open the StarUML and select Tools -> Extension Manager. is add an operand to the rectangle with that sequences guard and messages. Map out a real or hypothetical scenario that has many different components. The UML specification provides specific text values for diagram types (e.g. 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.
