When translating an ER model into database tables   a.) all of the entity attributes become the foreign keys. b.) the entity attributes become the tables. c.) for each entity, two tables need to be created. d.) the entity attributes become the fields of the new table.    The goal of normalization is to, (please select all that apply): a.) eliminate data duplication. b.) is create only 1:N relationships. c.) to create as few as possible tables to promote efficiency between the tables. d.) construct tables so that each table has a single topic or theme.

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.
