While at DevTeach in Toronto, Richard talks to Craig Utley about his experiences building business intelligence systems. The discussion starts out with the concepts of data warehousing, OLAP and business intelligence, and how many business owners get fooled into focusing only on the results of the business intelligence effort without acknowledging the huge body of work that goes into it with ETL, data cleansing and coherency. Craig talks about the right ways to get into a business intelligence project (it's about the business) so that you can avoid the pitfalls that lead to a failed project.
