Why use a sequence diagram for an attendance system?
A sequence diagram is crucial because it visualizes the chronological flow of messages between students, teachers, and the database. It helps developers identify potential bottlenecks or logic errors before coding begins. By mapping out every interaction, such as login authentication and data storage, teams can ensure the system is secure, reliable, and provides a seamless experience for all users.

What are the key actors in this diagram?
In this specific diagram, the two main actors are the Student and the Instructor. The student is responsible for logging in and marking their own attendance for specific classes. The instructor acts as an administrator who reviews the collected data, approves records, and makes manual adjustments if a student forgets to sign in or if technical errors occur during the process.

How does the system handle attendance data storage?
The system manages data through a continuous exchange between the Attendance System and the Attendance Database. When a student marks their attendance, the system first checks their eligibility. Once verified, it sends a storage request to the database. The database then confirms the record is saved, ensuring that every entry is backed up and available for the instructor to review later.
