Entity-Relationship Model vs. Extended Semantic Hierarchal model for conceptual modeling.
entityrelationsh00hand.pdf (3.487Mb)Abstract
This thesis investigates the area of conceptual data
modeling and looks for a model to serve as a vehicle for
designing improved semantic modeling capabilities. Several
possible models are discussed but the Entity-Relationship
model and the the Extended Semantic Hierarchal Model receive
special emphasis. Comparisons will be made of their advantages
and disadvantages regarding their suitability for
conceptual modeling. The Entity-Relationship Model is
chosen as being most capable of supporting enchanced conceptual
modeling techniques. Support for this position along
with recommended enhancements to the Entity-Relationship
Model and a suggestion for an automated graphical design
tool to improve its conceptual modeling capabilities are
provided in the final chapter.
