Eer Model. Subclasses and superclasses specialization and generalization category or union type attribute and relationship inheritance. With their enhanced features you can plan databases more thoroughly by delving into the properties and constraints with more precision.
With their enhanced features you can plan databases more thoroughly by delving into the properties and constraints with more precision. Eer models are helpful tools for designing databases with high level models. Subclasses and superclasses specialization and generalization category or union type attribute and relationship inheritance.

It reflects the data properties and constraints more precisely. Subclasses and superclasses specialization and generalization category or union type attribute and relationship inheritance. Features of eer model eer creates a design more accurate to database schemas. The resulting model is called the enhanced er or extended er model.
