The Enhanced Entity–Relationship (EER) model is an extended version of the Entity–Relationship (ER) model used in database design. It incorporates additional semantic constructs and modeling capabilities beyond the basic ER model, enabling more accurate representation of complex real-world scenarios through concepts such as specialization, generalization, union types, and inheritance.
The EER model was developed in the 1980s by database researchers including Ramez Elmasri and Shamkant Navathe to address the limitations of the basic ER model when modeling complex databases in domains such as engineering design, manufacturing systems (CAD/CAM), telecommunications networks, geographic information systems (GIS), and complex software applications.
