A MDA-Based Approach for Web Information System Development

Nowadays, new technologies and platforms are emerging and changing constantly, which implies a high effort developing software products. This situation generates different problems related to portability, integration and interoperability. The Object Management Group (OMG) proposes the Model Driven Architecture (MDA), which improves portability of applications by allowing the same model to be realized on multiple platforms. MDA defines an architecture based on platform independent models (PIM) and platform specific models (PSM). In this work we present MIDAS, a model-driven methodology based on MDA for the development of Web Information Systems (WIS). We apply the MDA metamodel to the Web platform using XML and (object-) relational technology. MIDAS proposes different PIMs and PSMs and defines some mapping rules between models. This paper also presents part of a case study to illustrate this proposal.
