In database development, a conceptual model is created, in the form of an Entity-relationship(ER) model, and transformed to a relational database schema (RDS) to create the database. However, some important information represented on the ER model may

This working paper proposes several modifications to the original ER modelling notation. The effort will help create ER diagrams (ERD) which are improved notation-wise and are of less confused, and which will in turn help design high quality relation

It is argued that ontologically clear entity relationship models can model the real world domains more accurately than ontologically unclear models. However, transformation of such models into the relational model at the logical level has not yet bee
