About This Architecture

Academic System ERD models a complete student enrollment and grading workflow with six core entities: MATERIAS, PROFESORES, ESTUDIANTES, GRUPOS, MATRICULAS, and CALIFICACIONES. Data flows from courses and instructors through class groups to student enrollments, culminating in grade records tied to each matriculation. This normalized schema enforces referential integrity and eliminates redundancy, critical for reliable transcript management and enrollment audits. Fork this diagram on Diagrams.so to customize entity attributes, add constraints, or export as .drawio for your database design tool. The 1:N relationships between MATERIAS→GRUPOS and PROFESORES→GRUPOS reflect real-world scenarios where one course and instructor manage multiple class sections.

How should I design a database schema for a student enrollment and grading system?

This Academic System ERD provides a normalized schema with MATERIAS (courses), PROFESORES (instructors), ESTUDIANTES (students), GRUPOS (class sections), MATRICULAS (enrollments), and CALIFICACIONES (grades). The 1:N relationships ensure each course and instructor can manage multiple groups, and each enrollment generates grade records, eliminating data redundancy and enforcing referential integrit
