Query: Building an Archive with Saada   Saada transforms a set of heterogeneous FITS files or VOTables of various
categories (images, tables, spectra ...) 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 homogenous 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.
