I took Nickolai's course on data warehousing. It was a subject that popularly has a lot of smoke around it. Nick's way of to-the-point explanation helped me immensely in understanding the subject. I would strongly recommend his courses to anyone who wants to learn complex topics in-depth without being bogged down by unnecessary clutter.
