This assignment focuses on modifying an existing Entity Relationship Diagram (ERD) for a college database. The modified ERD incorporates eleven entities, including student, campus, instructor, course, room, phone number, and email address. Key changes include separating the grade information into a dedicated table, normalizing phone numbers and email addresses, and implementing a many-to-many relationship between instructors and courses using an intermediate entity. The assignment emphasizes normalization up to 3NF and provides a detailed design summary explaining each modification and its rationale.
