Can anyone recommend web-sites or have any udeful tips for structuring queries and/or database design, hardware profiles so as to optimise some pretty heavy SQL processing
As far as I know, there is no "Formula" for improving performance. The definition of heavy SQL processing itself is not well defined yet.
It all depends on
-- The Resources available
-- The quality of the SQL code
-- The frequency
-- # simultaneous instances
-- and so on...
You may then choose a particular section of your interest.
But make sure, as you might already be aware of, tunning any parameter/code may result in performace-degrade on some other.
BTW, what kind of 'heavy SQL processing' you have. Is it like DW project pulling data from other servers and processing/formatting it before uploading?
