Abstract
In this work, a data integration approach using a federated model based on a service oriented architecture (SOA) is presented. The BioMOBY middleware was used to implement each service which is part of the integration process. As an example of usage of this architecture, a web tool for candidate SNP selection has been developed. Thus, several BioMOBY services have been created as the model layer of the web application. Each data source has a wrapper which communicates with the federated model, that is, the BioMOBY model, and this model is the one that interacts with the client.
