Abstract:
This paper proposes a new interface, visual database interface (VDI), for the novice end users to design, implement and query the database systems. The semantic data model used by VDI is an enhanced ER model (EER) with the inclusion of generalization/specialization, aggregation and categorization abstractions. The tools available in VDI include a graphical EER diagrammer for conceptual design and a graphical knowledge query language (VKQL) for data manipulation. The data definition and normalization tasks, which are considered to be the most difficult for end users, have been completely automated by the VDI Normalizer and the DB Creator.<>
