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.

Readers have a registration ID, name composed by first name and last name, mailing address and list of topics of interest (cooking, fiction, etc). The books available for readers will be stored with title, year of publication, isbn code and a list of topics that the book is tagged for.
