Applying MDA in Enterprise Application Interoperability: The PRAXIS Project

This paper elaborates on the application of the MDA approach for achieve interoperability among existing Enterprise Applications, such as Enterprise Resource Planning (ERP) and Customer Relationship Management (CRM) systems, through utilizing XML/B2B interconnection standards, developing components and modifying existing systems where necessary. We present the PRAXIS project design as a specific case study of this approach, describing the way in which interoperability-oriented high level model mappings are providing the means for guiding the model-driven development of interoperable Enterprise Applications. Specifically, we focus on the transformation processes that drive the Computation Independent System model into the Platform independent and finally the Platform Specific Model, including our final design decisions for the PRAXIS system
