Abstract

The ER model is the most popular model for database modeling. Its popularity is based on simple graphical representations, on graphical extensibility of given design and last but not least on safe constructs. The model strength is its strict hierarchic structure. This basis leads to safe implementations. There has been a large number of different extensions to the ER model both consistent and well-based or intuitive and seldom well-based. In this paper we demonstrate a safe path to extended ER models.

Meanwhile object-oriented model have gained large attention. Most of the object-oriented models are based on very powerful constructs which cannot be safely implemented. Some of the models are based on ER constructs with the extension of methods. We show that this approach is safe and powerful.
