Abstract
Using the ontology in information systems means an improvement of the possibility of solving tasks based on domain knowledge. The quality design of the ontological model is base of well-functioning system. In this area the most commonly used technology is MDA (Model driven development), which provides solid base for modeling language’s metamodel definition. This article aims to compare this technology with a new approach to visual modeling – the DSM (Domain-specific modeling) technology. Using the narrow focus on specific domain and full code generation the DSM allows easy and rapid development of the ontological system. The REA (Resource–Events–Agents) ontology, intended for business processes modeling was used for comparison of these technologies.
