The sequence diagram illustrates the process of managing student attendance in a system. The interaction begins with the Student logging into the system, where their credentials are authenticated by the Attendance System. Upon successful login, the student requests to view available classes, prompting the system to retrieve the relevant data from the Attendance Database. The student selects a class and marks their attendance, which the system verifies by checking their eligibility through a database query. Once confirmed, the attendance record is stored in the database.
The Instructor then reviews the attendance records for accuracy. The system fetches these records from the database and presents them to the instructor, who can either approve or make adjustments. Any changes made by the instructor are updated in the database, finalizing the attendance records.
