New transformation approach for Model Driven Architecture

The software development process is represented as propagation of the differences (modifications) within a set of models representing the software under development. The theory of system of complexes (configurations) is used to represent the model set of the software under development. The target of the research is to construct an approach to describe the process of the difference propagation as a basis of a corresponding instrumental environment for software development. The work extends the present MDA (Model Driven Architecture) approach.
