Modifying the Entity relationship modelling notation: towards high quality relational databases from better notated ER models [article]

Dhammika Pieris
<span title="2013-06-21">2013</span> <i > arXiv </i> &nbsp; <span class="release-stage" >pre-print</span>
The entity relationship modelling using the original ER notation has been applauded providing a natural view of data in conceptual modelling of information systems.  ...  In an effort to derive better transformations from ER models, we have understood that modifications should be introduced to both of the existing transformation algorithm as well as to the ER notation.  ...  also be modified in order to obtain high quality database models from ERDs.  ...

We illustrate by example the superiority of this model over the property graph data model of Hidders and other prevalent data models, namely the relational, object-oriented, XML model, and RDF Schema.  ...  It is difficult to ensure data quality for the properties and the data structure because the model does not need a schema.  ...  The extended Entity-Relationship (ER) diagram is shown in Figure 4 where the blue numbers next to the ER-symbols refer to the elementary transformations from Theorem 1.  ...

This paper addresses the design problems related to the modelling of ontologies, with specific concentration on the issues related to the quality of the conceptualisations produced.  ...  The paper aims to demonstrate the impact of the modelling paradigm adopted on the quality of ontological models and, consequently, the potential impact that such a decision can have in relation to the  ...  in order to produce high quality ontologies.  ...
