Enhanced ER Model

The enhanced ER model is an abbreviation for Enhanced Entity-Relationship (EER) model. As you know, the entity-relationship (ER) model is a pictorial illustration of the relationship between various entities of a domain. In the case of a large amount of data with multiple interrelated entities, the ER diagrams become complex and tough to interpret. For such cases, the need for enhancement in the ER model was observed, and thus, the EER model was designed.

Question

Design an Entity-Relationship (E-R) diagram for a university management system. The
system should capture information about the following:
. Students, with the following attributes: student ID, name, date of birth, and email address.
• Courses, with the following attributes: course ID, course name, and credit hours.
• Professors, with the following attributes: professor ID, name, and email address.
Additionally, consider the following relationships:
• A student can enroll in multiple courses, and a course can have multiple students enrolled.
• A course is taught by a single professor, and a professor can teach multiple courses.
Show all entities, attributes, and relationships in your E-R. diagram, including the cardinality of cach
relationship.
