A novel ER model to relational model transformation algorithm for semantically clear high quality database design [article]

Dhammika Pieris
2013 arXiv   pre-print
Conceptual modelling using the entity relationship (ER) model has been widely used for database design for a long period of time.  ...  However, studies indicate that creating a satisfactory relational model representation from an ER model is uncertain due to the insufficiencies both in the transformation methods used and in the relational  ...  CONCLUSION The existing ER to relational transformation algorithm is not able to provide a straightforward transformation of an ER model, and it also fails to transform most of the semantic information  ...

Semi-automatic Conceptual Data Modeling Using Entity and Relationship Instance Repositories [chapter]

Ornsiri Thonggoom, Il-Yeol Song, Yuan An
2011 Lecture Notes in Computer Science  
It is necessary to make it correct, as a poorly designed conceptual data model can lead to a poor database; hence, high costs and poor performance for decades to come.  ...  Even expert designers could fail to obtain a quality conceptual model due to their lack of domain knowledge, unless they have a clear perception of a requirement specification (N.  ...  Figure A.7 A Screenshot of Step 6 in EIPW Step 7: Identify relationships, which are not detected by RIR, by applying a modeling rule.  ...

Raising Time Awareness in Model-Driven Engineering: Vision Paper

Amine Benelallam, Thomas Hartmann, Ludovic Mouline, Francois Fouquet, Johann Bourcier, Olivier Barais, Yves Le Traon
2017 2017 ACM/IEEE 20th International Conference on Model Driven Engineering Languages and Systems (MODELS)  
We envision that Model-Driven Engineering (MDE) would be an appropriate ecosystem for a seamless and orthogonal integration of time into domain modelling and processing.  ...  The conviction that big data analytics is a key for the success of modern businesses is growing deeper, and the mobilisation of companies into adopting it becomes increasingly important.  ...  Generally, either they adapt the semantics of the existing ER model constructs to support temporal data, or introduce new constructs to the ER model.  ...

Evidence-based lean logic profiles for conceptual data modelling languages [article]

Pablo Rubén Fillottrani, C. Maria Keet
2019 arXiv   pre-print
In addition, due to the lack of a systematic design process of the logic used for the formalisation, hidden choices permeate the formalisations that have rendered them incompatible.  ...  We aim to address these problems, first, by structuring the logic design process in a methodological way.  ...  Notably, ER and EER originate from the relational database community [27] , UML Class Diagrams from object-oriented programming [80] , and ORM [52] bears similarities with semantic networks and can  ...
