Top-Down Approach for Web Services Development

This paper focuses on Web Services development presenting an approach that investigates the model-based software development towards Service-Oriented Architecture. This work explores software development based on Domain-Specific Modeling for building WSDL 2.0 meta-model. The Multiple Views CASE tool supports the development process of Web Services according to top-down approach through the creation of models at a high level of abstraction and the partial code generation. A case study in the Electronic Health domain illustrates the proposed in this work. The main contribution of the work is leverage agility and ease Web Services development process through high-level specification based on the meta-model.
