ESA New Generation Science Archives: State of the Art Data Management Techniques for SOHO and EXOSAT Science Archives

The Science Archives and VO Team (SAT) has undertaken the effort to build state of the art sub-systems for its new generation of archives. The new technology has already been applied to the creation of the SOHO and EXOSAT Science Archives and will be used to re-engineer some of the already existing ESA Science Archives in the future. As part of the new archives, the Data Layer infrastructure has had to achieve the goal of delivering an efficient and reliable access to millions of searchable elements in short response times.
