Building an archive with Saada

摘要

Saada transforms a set of heterogeneous FITS files or VOTables of various categories (images, tables, spec- tra etc.) in a database without writing code. Databases created with Saada come with a rich Web, interface and an Application Programming Interface (API). They support the four most common VO services. Such databases can mix various categories of data in multiple collections. They allow a direct access to the original data while providing a homogeneous view thanks to an internal data-model compatible with the characterization axis defined by the VO. The data collections can be bound to each other, with persistent links making relevant browsing paths and allowing data-mining oriented queries.
