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.
