This document describes a Dynamic Attendance Management System (DAMS) that was developed to more efficiently manage student and teacher attendance records using a centralized database and web interface. The system allows attendance to be taken and updated live, and personalized reports to be generated. It also functions as a student-teacher portal. Data mining techniques are applied to the attendance data to identify trends and predict student performance. Classification algorithms like ID3 and C4.5 are used to analyze factors like attendance, test scores, and past academic performance to generate performance predictions. The system aims to make attendance management simpler and more accessible through an easy-to-use interface and database backend.
