ER model Partitioning: Towards Trustworthy Automated Systems Development
Dhammika Pieris, M. C Wijegunesekera, N. G. J Dias
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 databas…
An Improved Generic ER Schema for Conceptual Modeling of Information Systems
Dhammika Pieris, M. C Wijegunesekera, N. G. J. Dias
The Entity-Relationship (ER) model is widely used for creating ER schemas for modeling application domains in the field of Information Systems development. However, when an ER sche…
Extending the ER Model to relational Model novel transformation Algorithm: transforming relationship Types among Subtypes
Dhammika Pieris
A novel approach for creating ER conceptual models and an algorithm for transforming them to the relational model has been developed by modifying and extending the existing methods…
A novel ER model to relational model transformation algorithm for semantically clear high quality database design
Dhammika Pieris
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 satisfac…
Modifying the Entity relationship modelling notation: towards high quality relational databases from better notated ER models
Dhammika Pieris
The entity relationship modelling using the original ER notation has been applauded providing a natural view of data in conceptual modelling of information systems. However, the cu…
