![]() 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. The sequence diagram example below shows the interactions between a user and a ticket booking system in booking a seat. What information is passed from one object to another? Create a UML state machine diagram Use case diagrams In the early stages of a development project, use use-case diagrams to describe real-world activities and motivations. The other set of components you must identify are the messages the objects will send. Use a state machine (or statechart) diagram to show the sequence of states an object goes through during its life. 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. 247 of the UML User Guide, illustrates the dynamic creation and destruction of objects, an object. ![]() The first necessary set of components are the objects. The following diagram, based on the one appearing on p. Exhibiting many alternative scenarios for the same use case. Providing an overview of collaborating objects within an object-oriented system. To accomplish these goals, you must first identify the components of your system that should be diagrammed. A few examples of instances where collaboration diagrams might be helpful include the following: Modeling collaborations, mechanisms or the structural organization within a system design. 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.
