SQL Skills offers Master training on SQL internals and so on: http://www.sqlskills.com/T_SQLskillsMasterImmersionEvents.asp
These classes are designed to be standalone training classes for anyone
wanting to know more about SQL Server.
While these are slated as “deep
events” we want to stress that you can
be really successful if you understand
a lot of the basic requirements of
data/databases but just not with SQL
Server. The first week – which starts
with internals and then moves into
database design and then ends with
indexing for performance – is the best
base that anyone can have that works
with SQL Server. This answers a lot of
the “how” and “why” questions in terms
of setup, design and tuning.
Paul used to work for Microsoft (on the SQL team) and Kimberly has been teaching and speaking on SQL forever. They are both incredibly entertaining and smart people - while I haven't taken courses from them I have been to sessions they've given and had technical conversations with them many times.
