I worked for 5 years as a DWH consultant with Teradata and like most of my colleagues, I had to struggle with performance problems. When I participated in one of Roland's workshops, I learned how to analyze and solve even the most complicated performance issues. Many thanks also for the wealth of free information on DWHPRO.

Roland's training helped me a lot to understand the relationship between SQL query performance and Teradata architecture. I am now able to identify the causes of slow queries and take appropriate measures to optimize them. DWHPRO is a valuable source of information about Teradata. I haven't found anything comparable yet.
