Form and Substance in Physical Database Design: An Empirical Study
As with many complex design problems, physical database design is difficult, ill-structured, and highly human intensive. In order to...
Towards the construction of workflow‐suitable conceptual modelling techniques
Despite their high-level and graphical nature, workflow specificationsrequire a significant amount of implementation detail Ð for example applicationprogramming interface,...
Are Attributes Entities? A Study of Database Designers’ Memory Structures
A longstanding debate in the data modeling literature pertains to whether the grammars used to generate conceptual schemas should...
The role of modelling in achieving information systems success: UML to the rescue?
Much computer science literature addresses the mechanics of theUnified Modelling Language (UML) and requirements modelling, but little researchhas addressed...
Should Optional Properties Be Used in Conceptual Modelling? A Theory and Three Empirical Tests
An important feature of some conceptual modelling grammars is the features they provide to allow database designers to show...
Semantic database prototypes
This paper describes a technique for improving the semantic consensus of conceptual database designs. Semantic consensus is a condition...

The effect of graphic style on data model interpretation
Graphic data models are commonly used as a tool for presentation ofinformation structures in the design, implementation, use and...
Extending Classification Principles from Information Modeling to Other Disciplines
Classifying phenomena is a central aspect of cognition. Similarly, specifying classes of interest is a central aspect of information...
Ontological Clarity, Cognitive Engagement, and Conceptual Model Quality Evaluation: An Experimental Investigation
When analysts build information systems, they document their understanding of users’ work domains via conceptual models. Once a model...
