To check and ascertain no errors, user comments in the HTML have to be converted into Java objects and probable authentication faults, then back into JavaScript callbacks. Comments written and submitted by the users are initially validated by the website hosting service.

Submission of comments in UML sequence diagram. The student is then allowed to access the information he/she requires for a case, for instance: class list, grades, and after that, their mission gets accomplished, and he/she has successfully done what he/she intended to do. When a student logs in into the system, their identity is identified by the system admin, and they get validated on account of the correct credentials.

Above is an example of a UML sequence diagram that shows the process of registration.Įxample 3: Login Student System Sequence DiagramĪ better example to illustrate the UML diagram is by showing students' login to the school system. But before that, objects and classes will be displayed in a registration process system. The functionality of the entire system is influenced by the sequence of messages exchanged amongst its objects. 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.
