Extended Entity Relationship Modeling
2005With the rising complexity of database applications, the basic concepts of Entity-Relationship (ER) modeling (as originally developed by Chen, 1976) were no longer sufficient. So the basic ER model was extended to include generalizations and specializations (Bagui & Earp, 2003; Elmasri & Navathe, 2003) and the concept of categories (Elmasri ...

Expressing a Temporal Entity-Relationship Model as a Traditional Entity-Relationship Model
2015According to the approach of conceptual database design, database models are designed from the Entity-Relationship (ER) model. However, the real world of most database applications are related to the temporal aspects, so data modelling using the ER diagrams had encountered many difficulties.

Extended Entity-Relationship Model
2009DEFINITION The extended entity-relationship (EER) model is a language for definition of structuring (and functionality) of database or information systems. It uses inductive development of structuring. Basic attributes are assigned to base data types. Complex attributes can be constructed by applying constructors such as tuple, list or set constructors

In the remaining chapters, we discuss the extended entity-relationship model, the higher-order entity-relationship model HERM. However, in order to understand why it is necessary to extend the model, we will briefly discuss the original ER model first published by Chen [Che76]. It has been extended or restricted by several authors.

Entity Relationship Modell (ERM)
1991In der wirtschaftberuflichen Ausbildung wird zunehmend ein systemisches Denken und Handeln in kom-plexen wirtschaftlichen Zusammenhangen gefordert. Probleme der unterrichtlichen Umsetzung sind u. a. in fehlenden Beschreibungs verfahren fur Prozesse und Ablaufe in sozio-technischen Systemen, wie Betriebe, begrundet.
