Master data science & ai from fundamentals to advanced concepts with this comprehensive course.
Dive into the world of Data Analysis Expressions (DAX) in Power BI with my comprehensive course, designed to take you from fundamentals to advanced techniques. This course is ideal for those who have a basic understanding of data connecting and transformation fundamentals in Power Query, as well as data modeling basics (no worries even you don't have fundamental knowledge of data transformation and modeling, I have covered Data transformation and modeling fundamentals to get started DAX). Course Highlights:Fundamentals covered: Refresh your knowledge on data connecting and transformation fundamentals in Power Query and data modeling essentials to ensure a strong foundation.
DAX Essentials: Understand the DAX engine, including row context and filter contexts, and explore calculated tables, calculated columns, and measures. Learn the differences between implicit and explicit measures. Aggregation Functions: Master core DAX functions for aggregation such as SUM, MIN, MAX, AVERAGE, COUNT, DISTINCTCOUNT, and COUNTROWS.
Advanced DAX Techniques: Delve into CALCULATE functions, context transition, and the use of variables and measure tables for dynamic calculations. Iterator Functions: Learn to apply iterator functions like SUMX, MINX, MAXX, AVERAGEX, and COUNTX to iterate over tables and perform complex calculations. Filter Functions: Utilize filter functions including FILTER, ALL, ALLEXCEPT, and ALLSELECTED to manage and manipulate data contexts.
Information Functions: Explore functions like SELECTEDVALUE, HASONEVALUE, ISBLANK, ISEVEN, ISODD, ISTEXT, ISFILTERED, CONTAINSSTRING, and ISINSCOPE for effective data evaluation. Logical Functions: Apply logical functions such as IF, AND, OR, SWITCH, and COALESCE to create robust and dynamic expressions. Mathematical Functions: Use mathematical functions like ABS, VALUE, MOD, ROUND, and DIVIDE for precise calculations and transformations.
