A FRAMEWORK FOR THE DEVELOPMENT AND DEPLOYMENT OF EVOLVING APPLICATIONS - The Domain Model

Abstract

Software development is an R&D intensive activity, dominated by human creativity and diseconomies of scale. Model-driven architecture improves productivity, portability, interoperability, maintenance, and documentation by introducing formal models that can be understood by computers. However, the problem of evolving requirements, which is more prevalent within the context of business applications, additionally calls for efficient mechanisms that ensure consistency between models and code and enable seamless and rapid accommodation of changes, without interrupting severely the operation of the deployed application. Having presented a framework that supports rapid development and deployment of evolving web-based applications, this paper elaborates on the Domain Model that is the cornerstone of the overall infrastructure.
