Study Notes
EER Model Concepts
- EER stands for Enhanced Entity Relationship
- The EER model includes concepts such as subclasses, superclasses, and categories
- A category is an entity type that may have additional meaningful subgroupings of its entities, referred to as subclasses
- Categories allow for further classification and grouping of entities
Subclasses and Superclasses
- Subclasses are used in EER modeling to represent a specialized version of an entity type
- Superclasses are used in EER modeling to represent a generalized version of an entity type
- Subclasses inherit the attributes of their superclass, and may also have additional attributes
- Subclasses and superclasses are used to model real-world situations where objects have a hierarchical relationship
