Introduction This is part 1 in a series of articles I plan to write over in the coming weeks regarding the use of Aggregate Tables in Analysis Services databases. Some of the techniques covered in this series have been developed after working on some of the largest models around. The series will cover : Introduction … Continue reading Creative Aggs Part I : Introduction
In this article, I’m going to describe a technique you may wish to consider to help speed up your Power BI reports. This specific technique is designed to help speed up reports that show common period comparisons such as: This year versus last year (as difference and/or percent) Delta, or percentage change over the previous … Continue reading Pivoting Data for Speed
