Software performance model-driven architecture

Abstract

Model transformations in MDA mostly aim at stepping from a Platform Independent Model (PIM) to a Platform Specific Model (PSM) from a functional viewpoint. In order to develop high quality software products, non-functional attributes (such as performance) must be taken into account. In this paper we extend the canonical view of the MDA approach to embed additional types of models that allow to structure a Model Driven approach keeping into account performance issues. We define the relationships between MDA typical models and the newly introduced models, as well as relationships among the latter ones. In this extended framework new types of model-to-model transformations also need to be devised. We place an existing methodology for transforming software models into performance models within the scope of this framework.
