Here is some feedback

Bob from Zoetermeer, Netherlands

"The SQL Server Query Tuning Workshop helped me as a developer to realize how important a good indexing strategy is for a responsive application. In my opinion every developer, working with SQL Server, should know how the indexes are build up, and how the query optimizer is getting to his query plan."

Roger from Hertogenbosch, Netherlands

"During the workshop I have learned a lot about the query optimizer internals and how I can use that knowledge to write optimal performing queries. Klaus obviously knows a lot about these topics and is able to teach them very well. I can’t wait to attend one of his workshops in the near future."

Thomas from St. Margrethen, Switzerland

"I was lucky enough to attend the 4 day long SQL Server Query Tuning Workshop from Klaus in Zurich. He has presented in a very easy way the performance related internals of SQL Server that will help you to write better performing SQL queries. Based on that knowledge I finally know now why sometimes queries are fast, and sometimes are slow. It was an amazing workshop, which makes the day-to-day work with SQL Server now very easy."

Arun from London, United Kingdom

"My day-to-day writing of SQL has gone up a level – I am able to finely tune individual statements or underlying database objects to get the kind of query plan I want. Moreover I know now what sort of plan I am looking for. I have been already able to use this knowledge to address performance issues that came up this week in capacity testing."

Bernd from Monheim, Germany

"After attending the 4 days long workshop you know very exactly how SQL Server executed SQL queries on the logical and physical level through execution plans. In addition you will know how you can improve queries by applying the right indexing strategy. This in-deep knowledge was very well explained and presented by Klaus."

Ina from Oberhaching, Germany

"Anyone faced with the task to implement queries on complex ERP data structures – for reporting, providing views, or for statistical analysis – comes quickly to its limits without knowledge of the operation of SQL Server. The workshop provides an excellent insight into the technical world of SQL Server, explained with many examples of queries and their optimization."

Filip from Beerse, Belgium

"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."

"It does not matter how long you have been working with databases, there is so much in this course that you are guaranteed to learn a great deal. I have been working with databases for 20 years and I have never gained as much knowledge of database internals in such a short period. I have been searching for some time for a course like this and this is packed with valuable techniques and tips."

I had a lot of light bulb moments and it gave me a much better feeling for the practical techniques that can be used in the field and how things are related.

"Five days of pure SQL knowledge were described in excellent manner. The day after I was able to understand the behavior of my databases and its execution plans in a much better way. I also know how important a good index strategy can be and how I can handle the locking und blocking behavior within my databases. Klaus explained all the necessary knowledge in a simple way and showed everything with a lot of good examples. Thank you."
