Multimodel-Driven Software Engineering for Evolving Enterprise Systems

We advocate the use of multimodel-driven software engineering for the principled evolution of enterprise systems whose stakeholder concerns are captured using multiple interdependent models. Enterprise systems that evolve are increasingly common in healthcare, transportation, e-government and defense. These important systems must be regularly extended with new components satisfying interdependent functional, governance and quality-of-service (QoS) requirements that are modelled using different domain-specific languages. We describe key challenges associated with modelling, reasoning about QoS properties, and evolving such systems. The concepts of this engineering paradigm are presented in the context of a statistical reporting project carried out in collaboration with healthcare organisations.
