Part I: Entity–Relationship (ER) DiagramER Diagram for BS.

This Entity–Relationship (ER) Diagram represents the academic management system for BS Information Technology (BSIT), BS Computer Science (BSCS), BS Data Science (BSDS), and BS Artificial Intelligence (BSAI) programs. The diagram illustrates the major entities involved in the system, their attributes, and the relationships among them. The system includes entities such as Student, Department, Program, Course, Instructor, Semester, and Enrollment. Each entity contains relevant attributes that describe its information, while primary and foreign keys establish connections between related entities. The ER diagram also represents important relationships, such as students enrolling in courses, instructors teaching courses, programs offering courses, and departments managing academic programs. Cardinality and participation constraints are used to clearly define how entities are associated with one another. Overall, the ER diagram provides a structured and professional representation of the database requirements for managing students, academic programs, courses, instructors, and enrollments across BSIT, BSCS, BSDS, and BSAI programs.
