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.

For such cases, the need for enhancement in the ER model was observed, and thus, the EER model was designed.
