The Extended Entity Relational Model(EER) can support a lot of functions which are not covered with existential Entity Relational Model. However, some respects in the Object Model, such as inheritance and generalization, are not able to be supported in the EER Model.
We compare the EER Model with the Object Model by mapping their properties.
Especially we analyze generalization and inheritance in the Object Model and introduce them into the EER Model.
