College System ER diagram models a multilingual (Arabic-English) relational database for managing students, departments, courses, instructors, and enrollments across a college hierarchy. The schema establishes relationships from College → Department → Student, Course, and Instructor, with Enrollment as a junction table linking Students to Courses and capturing grades. This normalized structure ensures data integrity, eliminates redundancy, and supports complex queries for academic reporting and student record management. Fork this diagram on Diagrams.so to customize entity attributes, add additional relationships like prerequisites or grading scales, or export as .drawio for use in your database design documentation. The bilingual labeling makes it ideal for institutions serving Arabic and English-speaking stakeholders.
