DBMS-Enhanced Entity-Relationship (EER) Model Questions and Answers
The DBMS Enhanced Entity-Relationship (EER) Model questions with answers help students understand advanced database modeling techniques like specialization, generalization, and aggregation. These database programming questions and answers are important for placements and competitive exams where data modeling and schema design play a key role. Practicing EER model MCQs improves your conceptual understanding and helps you perform better in DBMS interviews and tests by TCS, IBM, and Infosys. Learn the extended concepts of ER modeling with clear explanations and real-world examples.
