Entity-Relationship Diagram (ERD) for a complete university management system modeling students, courses, disciplines, professors, departments, scholarships, and academic prerequisites. The schema captures core entities—ALUNO, CURSO, DISCIPLINA, PROFESSOR, DEPARTAMENTO, BOLSA—with associative entities MATRICULA and CURSADA managing many-to-many relationships and academic performance tracking. Data flows from student enrollment through course registration and discipline completion, with prerequisite constraints enforced via the PRE-REQUISITO self-referencing entity. This normalized design supports institutional reporting, transcript generation, and enrollment validation while maintaining referential integrity across all academic operations. Fork and customize this diagram on Diagrams.so to adapt it for your institution's specific data model, add additional attributes, or export as .drawio or PNG for documentation and stakeholder review.
