Discussing the Difference between Model Driven Architecture and Model Driven Development in the Context of Supporting Tools

The most current trends in the evolution of software development process are closely related with the increasing complexity of software systems. This motivates software engineers and system developers to find an alternative solution for software system design and development. In this case, the manner offered by OMG´s initiative, the model driven architecture namely, represents a model driven approach to software development. It also considers the further evolution of CASE tools, bringing their functionality to the next level. This paper investigates the variety of the CASE tools developed under an impact of MDA growing progress. The differences between model driven architecture and model driven development in the context of automatic capabilities for software development are also discussed in the paper. The example of possibility to define a set of tools proposed as a tool chain for development of software systems under the framework of MDA, the projection of two-hemisphere approach for object-oriented software development into authors´ developed component model of MDA is offered in the paper.
