To convert an ER diagram into normalized relations up to Third Normal Form (3NF), each entity and relationship is transformed into relational tables while ensuring elimination of redundancy and dependency anomalies. Each strong entity becomes a relation with its primary key (PK). For example, STUDENT (Student_ID PK, Name, Address, Phone) and COURSE (Course_ID PK, Course_Name, Credits). Weak entities include the primary key of the owner entity as a foreign key (FK), such as RESULT (Result_ID PK, Student_ID
