About This Architecture

University database ER diagram modeling four core entities—Department, Professor, Course, and Student—with primary and foreign key relationships. Departments manage multiple professors and courses, professors teach courses and lead departments, and students enroll in department-specific programs. This normalized schema demonstrates best practices for academic institution data modeling, including referential integrity and clear cardinality constraints. Fork and customize this diagram on Diagrams.so to adapt it for your institution's specific requirements, then export as .drawio or .png for documentation and team collaboration.

How should I structure a university database with departments, professors, courses, and students?

This ER diagram shows a normalized four-entity design where Departments manage Professors and Courses, Professors teach Courses and lead Departments, and Students belong to Departments. Primary keys (dept_code, professor_id, course_id, student_id) and foreign keys enforce referential integrity across all relationships.
