A system and method that implements top-down and bottom-up model-driven transformations between platform-independent (business view) modeling approaches and platform-specific (IT architectural) models. On the business level, business view models may be expressed in, but not limited to ADF or UML2, whereas on the IT architecture side, service-oriented architectures with Web service interfaces and processes are specified in business process protocol languages including, but not limited to, BPEL4WS, or workflow definitions. An architecture and a transformation method based on typed information flows automatically transforms platform-independent business models into executable information technology (IT) architecture specifications constrained by a specific IT platform, and vice versa. The models generated span the entire life cycle of a software system and ease the software production, deployment and maintenance tasks. That is, the different models generated for the same system are "linked" in a way that relevant changes in one model may be propagated to the other models to keep the model set consistent.
