>> I've been working as a physical DBA for a long time and have developed my instance tuning skills rather well. I have felt pretty much the same way in the past though have now spent the last 2 years thinking of ways that would make SQL tuning more efficient for the DBA and developer so I could help design a better software interface to help with SQL tuning. I'm at the point where the results are starting to show now in DB Optimizer. This article by Jonathan Lewis is short and sweet and covers some of the main points of efficient SQL execution plans: http://www.simple-talk.com/sql/performance/designing-efficient-sql-a-visual-approach/ Much along the lines that Jonathan outlined, I've been working on automating the visual diagramming and statistical analysis in software, in DB Optimizer. If you didn't see the earlier post , Jonathan and I are co-presenting a webinar on the ideas: http://db-optimizer.blogspot.com/2010/05/visual-sql-tuning-webinar-with-jonathan.html Best Wishes Kyle Hailey http://db-optimizer.blogspot.com On Sun, Jun 6, 2010 at 7:19 PM, Guillermo Alan Bort <cicciuxdba@xxxxxxxxx>wrote: > Listers, > > I've been working as a physical DBA for a long time and have developed my > instance tuning skills rather well.
