  1. What next? Bob Mann

  2. Summary: requirements for Edinburgh sky survey databases • Scalability • Handling 1-10TB of catalogue databases • Spatial indexing crucial to performance • Interoperability • Easy integration into web/Grid service framework • Ease of use • No professional DBA, part-time job for astronomer • Cost • Limited funds for hardware/software in academia

  3. One possible approach • Goal: • Build copies of the combined SuperCOSMOS and SDSS dataset in the SDSS EDR region • Do this for both DB2 and Oracle • Run SSA “20 queries” on them • Variants: • Get HTM working in DB2 and Oracle • Implement fGetNearbyObjEq() using native spatial indexing in DB2 and Oracle • Implement new Gray-Szalay geometric approach?…. • What else?
