In an Advanced Database Management System context, the EER (Extended Entity-Relationship) diagram enhances the traditional ER model by incorporating additional concepts such as specialization, generalization, categories, multi-valued attributes, and derived attributes. For a typical database scenario involving, for example, a university management system, we first identify the entities, their attributes, and the relationships among them. Entities can include `Student`, `Course`, `Instructor`, and `Department`. Each entity has specific attributes: `Student` may have `Student_ID` (primary key), `Name`, `DOB`, `Address`, `Phone_Number`, and `Email`.
