"This training on SQL Server performance tuning was extremely interesting. Klaus taught me lot of things I was not aware of. I especially loved the tips he gave on common mistakes and wrong concepts about SQL Server. Such information, coming from an independent expert (“expert” is still very understimated when talking about Klaus’ knowledge), is a lot more valuable than spending hours reading and googling. This training has a high return on investment and anyone who is seriously working with SQL Server should attend this workshop."
