This UML sequence diagram for the school management system depicts important interactions among students, teachers, and administrators. The users start by logging into the system triggering an authentication process followed by actions like course registration for students, grade entry for teachers, and error handling for failed operations. Students can access their grades while administrators perform course addition and report generation tasks.
Alternative conditions have been used in the diagram to show decision-making aspects like whether a student could successfully view their grades or get errors hence showing how the system manages each user’s request-response flow.
