Oh really, there ARE guys with deep insight into Microsoft SQL server. This notes absolutely look like a willing professional who did learn something new: http://blogs.technet.com/b/josebda/archive/2009/03/20/sql-server-2008-fragmentation.aspx
But what about me? I am still looking for a course or material giving me the SQL Server architecture and logic in a way I can understand. At least one resource that looks promising in this sense: http://www.akadia.com/services/sqlsrv_data_structure.html
Sad feeling: SQL Server seems to be much, much more an oracle than Oracle is to me.
Struggeling on ;)
