The arrowhead used to show this type of message is a simple line arrow with a dark-colored tip, as shown in the diagram above.Įxample 2: Registration Process Sequence Diagram

An asynchronous message passed between the customer, login screen, and security management is employed when the message dialer does not wait for the receiver to process the message and make a response before sending other messages to other already defined objects within the proposed system.

They use it to illustrate how the different parts of a system will interact with each other and sequential order to achieve a desirable outcome.Ī case in point to help you visualize and fully grasp the UML sequence diagram is as follows. In more than half of the instances of using the sequence diagram, IT developers will more times than not be using them.

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. 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.
