Entity-relationship diagram modeling a remote industrial attachment registration system with five core entities: Student, Company, Registration, Document, and Supervisor. Students register for industrial attachments at companies through a Registration entity that tracks dates and status, while Documents store uploaded files linked to each registration. Companies employ Supervisors who manage student placements, and Administrators oversee the entire system through authentication and registration management. This ERD demonstrates normalized database design for academic internship tracking, ideal for universities managing remote work placements.
