Seamlessness as a Desirable Aspect of Quality for MDE: The Contribution of Object-Relational Database Stuctures

Where model-driven approaches are used in Information Systems development, as well as transforming models into application code, an important and often overlooked aspect is the transformation into storage schemas for persistent data. Relational database schemas are still being used but these might not be the best quality solutions for persistent data. Object-relational database management systems (ORDBMS) can store persistent data using structures that have more in common with object-oriented application code structures. Seamless transformations may have the quality that is desirable for model-driven approaches. In this paper we demonstrate the advantages of seamless transformations. We show object-relational structures that contribute to seamless ness and the implications for model-driven approaches such as Model-Driven Engineering.
