This UML sequence diagram for an Online Examination System outlines the process of a student logging in, taking an exam, and receiving their score. The student logs into the system, which verifies credentials with the database. Once confirmed, the system grants access to the exam. The student begins the exam, and the system retrieves questions from the Question Bank and displays them. After submitting the answers, the system evaluates them using the Answer Key and provides the scores to the student. Finally, the student logs out of the system.

About sequence diagrams

Sequence or event diagrams help create an overview of how a system works. Sequence diagrams show how all the different parts interact with each other over time, carry out the required actions, and complete processes. A sequence diagram descends from top to bottom showing a sequence of interactions and sequence diagram notations.
