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 highlevel specification based on the meta-model.
