About This Architecture

Complete university management system DER (Entity-Relationship Diagram) modeling student enrollment, courses, departments, professors, and academic prerequisites. The schema connects ALUNO (students) to CURSO (courses) through MATRICULA_DISCIPLINA (enrollment records), with PROFESSOR and DEPARTAMENTO entities managing faculty and organizational structure. DISCIPLINA (subjects) link to courses and professors while PRE_REQUISITO and BOLSA (scholarships) entities handle academic dependencies and financial aid. This normalized relational design demonstrates best practices for academic institutions managing complex multi-entity relationships, cardinality constraints, and referential integrity across student lifecycle workflows. Fork this diagram on Diagrams.so to customize entity attributes, add new tables like AVALIACAO or HORARIO, or export as .drawio/.sql for database implementation. The schema supports reporting on student performance, course capacity, departmental budgets, and prerequisite validation across semesters.

How do you design a database schema for a complete university management system with students, courses, professors, and prerequisites?

This DER diagram models a normalized relational schema with ALUNO (students), CURSO (courses), PROFESSOR (faculty), DEPARTAMENTO (departments), DISCIPLINA (subjects), MATRICULA_DISCIPLINA (enrollment), PRE_REQUISITO (academic dependencies), and BOLSA (scholarships). The design uses primary and foreign keys to enforce referential integrity, N:N associative entities for many-to-many relationships, a
