Data modelling frameworks consist of a series of constructs which are used to create an abstraction of the world. Ontologies consist of concepts through which reality can be described. The aim of this paper is to use an ontology as a basis for comparing and evaluating data modelling frameworks. We begin by establishing a method for comparing modelling frameworks using ontology, and then examine...

While some service providers of Massively Multiplayer Online Role-Playing Games (MMORPGs) lose significant numbers of players over time, others maintain a strong growth trajectory. Drawing from the Uses and Gratifications Theory and the Need to Belong theory, we believe that an individual’s Perceived Belonging (i.e., the degree to which a person feels connected to and accepted by others) positi...

system dynamics is a strategic approach for modeling complex systems and analyzing their behavior. dynamic behavior in entrepreneurial system can be modeled using system dynamics approach and dynamic hypotheses about the system`s behavior can be proposed and tested using simulation and computer aided tools. however, as the review of literature shows, studies which link system dynamics modeling ...

This paper describes the conceptual integration and computer-based support of two important groups of conceptual data models, Entity Relationship Models and Object Role Models (e.g. NIAM). We perform conceptual integration using the conceptual data modelling language CoCoA to specify separate data models of individual notations. We then merge these into an integrated conceptual data model for b...
