Practitioners view on modeling with domain specific languages is presented in this paper. It is shown, that unlike general-purpose modeling languages, domain specific languages provide means for concise representation of semantics of the particular business domain, enabling development of consistent and expressive business process models. Resulting models can be used not only as specifications for information systems, but also for generation of implementation artifacts, creating documentation, testing and for other purposes. Thus one of the most principal goals of model driven architecture – the development of model-based information system – is achieved.
