Abstract The domain knowledge represented by ontology should be widely used in the design process of information system. Expand

We define an algorithm which transforms any statechart into a LOTOS behaviour expression. Expand

A conceptual model is a high-level, graphical representation of a specic do- main, presenting its key concepts and relationships between them. Expand

We propose a method for constructing a conceptual model discovered from data frames encompassed in data files, based on functional dependencies among analyzed data, gathers identified properties into classes and finds relationships among them. Expand

We propose a method for evaluation of logical database models in the context of transaction performance. Expand

The paper concerns the concept of refinement as a commonly used design practice in the software development process. Expand
