Applying MDA approach for Web service platform

We present the development of an illustrative example of e-business based on two different applications of a Model-Driven Architecture (MDA) approach. In the first application, the platform-independent model (PIM) is created using the Unified Modeling Language (UML). This PIM is transformed using Atlas Transformation Language (ATL) to generate the platform-specific model (PSM) based on three target platforms: Java, Web service and Java Web service developer pack (JWSDP). In the second application, the PIM is created using enterprise distributed object computing (EDOC) and transformed into another PSM based on the same target platforms. For this purpose we use the illustrative example of a travel agency to depict some issues of the approach. Then, we discuss mappings between meta-models.
