Power Pivot And Power BI Data Modeling

Avi Singh has a post on data modeling in Power Pivot and Power BI:

It was Greg, who suggested that we form a book reading club. Our first book was one I had heard about, but never read – The Data Warehouse Toolkit: The Definitive Guide to Dimensional Modeling By Ralph Kimball. As a business analyst, I had leaned heavily on Excel, along with a mishmash of other technologies. Data warehouse and data modeling didn’t seem like topics that would be relevant to me; more for an IT/BI team perhaps. But I figured, it couldn’t hurt to learn something new.

Our book club meetings looked more as if, class was in session. We brought in our questions, and Greg patiently answered them, helping us realize the importance of the topics, and trade-offs involved in various choices. As things go, our reading club was disbanded before we were even halfway through the book. But the knowledge that I had gained, helped me grow by leaps and bounds in my Power Pivot and Power BI journey.

Kimball-style fact-dimensional modeling remains a brilliant solution.
