| Abstract: |
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 at helping them by automatically generating from data files databases (SaadaDBs) located on any local computer. SaadaDBs can simultaneously host heterogeneous sets of spectra, images, source lists or any other files. Data stored in SaadaDBs can be correlated each to others 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 and data models providing then a solution to publish local data into the VO. |
