A lot of astronomers would like to share datasets with the community but have no manpower to develop databases providing functionalities with high scientific level. The Saada project aims to help them by automatically generating from Fits files or VOtables databases (SaadaDBs) located on any Linux, Windows or Mac computer. SaadaDBs can simultaneously host heterogeneous sets of spectra, images and source lists. Data stored in SaadaDBs can be correlated each other with qualified links helping for example for cross-identifications or for modeling some other scientific content. The query engine is based on a specific language (SaadaQL) fitting well the data model. In addition with classical astronomical queries, it can process constraints on correlated data. Databases created by SAADA can be accessed by a WEB interface allowing data browsing or data selection with complex queries. They also implements VO protocols providing then a solution to publish local data into the VO.
