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
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?….
