Représentation de schémas de bases de données hétérogènes sous forme de métaschémas XML

Abstract : Databases management systems use various structures and storage formats to represent the same information. Due to this heterogeneity, both data integration and simple data exchange are difficult, if the various actors (data producers and consumers) to not agree on the semantics of the data. It is thus very difficult to find the semantics of a concept in all the databases where it can be represented. To solve this problem, we conceived a system primarily focused on recovering and modelling multiple heterogeneous databases schema in the form of XML metaschemas. The extraction is automated and makes it possible to progressively integrate new databases in a uniform concept representation, without extracting the data itself. The metaschema are used to describe and express the semantics of the original schema of the databases to be federated.
