Scientific paper

As members of the Survey Science Consortium of the XMM-Newton mission the Strasbourg Observatory is in charge of the real-time cross-correlations of X-ray data with archival catalogs. We also are committed to provide a specific tools to handle these cross-correlations and propose identifications at other wavelengths. In order to do so, we developed a database generator (Saada) managing persitent links and supporting heterogeneous input datasets. This system allows to easily build an archive containing numerous and complex links between individual items [1]. It also offers a powerfull query engine able to select sources on the basis of the properties (existence, distance, colours) of the X-ray-archival associations. We present such a database in operation for the 2XMMi catalogue. This system is flexible enough to provide both a public data interface and a servicing interface which could be used in the framework of the Simbol-X ground segment.
