Génération automatique des requêtes de médiation dans un environnement hétérogène

Abstract : Nowadays, mediation systems are widely used. However, their implementation raises several problems, especially the definition of mediation queries when there is a high number of sources, and an important amount of metadata. The heterogeneity of the data sources makes this problem even more complex.
We propose in this thesis an approach to automatically generate the mediation queries in a relational context. Our algorithm produces a set of possible mediation queries given the description of a set of heterogeneous and distributed data sources. We have developed a tool to automatically generate mediation queries in a heterogeneous context. We provide some performance evaluations to test the scalability of our tool, and to show its usability for systems of different size.
