NERD: A Learning Tool for Database Normalization and ERD Development

Abstract

Data modelling has been a complicated task for students taking up a database course as well as for beginner developers. However, data modelling should not be ignored by people in a database related course or profession as it is required to develop a well-structured database. Although data modelling, ER modelling in particular, is a complicated task, it is not well provided with tool based support [7]. Several model development tools exist but learning tools for data modelling are very minimal in number. This study intends to develop a computer-aided instruction (CAI) for the development of entity-relationship diagrams and normalization.
