Transformation rules can be defined in two ways -- theoretical and empirical. A theoretical-based definition of transformation is a formal way to prove and verify some theory. Therefore, it is precise, the likelihood of errors is reduced, it is easier to tell where it is wrong and correct it, and the quality of specification of the transformation can be(More)
Nowadays business processes (BP) are dynamic by their nature and affected by dynamically changing environment. However, traditional approaches and tools used to model, simulate and implement BP no longer covers the actual needs of the business, which should be dynamic. Moreover, business needs tools, which support such dynamic BP modelling and simulation.(More)
Nowadays, ontologies play a central role in many computer science problems such as data modelling, data exchange, integration of heterogeneous data and models or software reuse. Yet, if many methods of ontology based conceptual data modelling have been proposed, only few attempts have been made to ontology axioms based modelling of business rules, which(More)
The traditional approach used to implement a business process (BP) in today’s information systems (IS) no longer covers the actual needs of the dynamically changing business. Therefore, a necessity for a new approach of dynamic business process (DBP) modelling and simulation has arisen. To date, existing approaches to DBP modelling and simulation have been(More)
