Power BI: Mastering DAX for Data Analysis (TTDPB05)

 About this Course

If you are already using Power BI but want to get more out of your reports, Mastering
DAX and Data Analysis is for you. DAX (Data Analysis Expressions) is the formula
language that powers Power BI, giving you the ability to create dynamic calculations,
shape data effectively, and improve report performance. Whether you are struggling
with complex measures, trying to fix unexpected results, or looking to speed up slow
reports, learning DAX will help you take full control of your data.
In this fast-paced, hands-on, expert-led course, you will work with real-world scenarios
to build DAX skills that make a measurable difference in how you create and manage
Power BI reports. You will learn how to write accurate and efficient expressions, control how filters and row context impact your calculations, and apply advanced functions to
solve common data challenges. You will also explore best practices for optimizing
performance, setting up security roles, and using external tools to analyze and refine
your formulas. By the end of the course, you will be able to create faster, smarter, and
more insightful Power BI models that drive better decisions.
This course is designed for Power BI users who already have a solid understanding of
basic report building and want to sharpen their skills with DAX driven data modeling and
calculations. If you are a data analyst, business intelligence professional, or report
developer, or if you work with Power BI in any role where accuracy and efficiency
matter, this course will give you the tools and confidence to create more powerful and
reliable reports. No prior DAX expertise is required. You just need a working knowledge
of Power BI and a desire to improve your reporting skills.
Objectives
In this expert-led, hands-on course, you will build the skills to confidently write and
troubleshoot DAX expressions, improving the accuracy and efficiency of your Power BI
reports.
By the end of this course, you will be able to:
· Write clear and effective DAX expressions that return the right results and are easy to
maintain.
· Control how filters and row context affect your calculations so your reports always reflect
the right data.
· Speed up slow reports by using best practices for DAX and optimizing your data model.
· Use CALCULATE and other key functions to create dynamic, flexible measures that
respond to different filters and conditions.
· Set up Row-Level Security (RLS) to control access to data and ensure users only see
what they should.
· Work with external tools like DAX Studio to analyze and fine-tune your expressions for
better performance.
If your team requires different topics, additional skills or a custom approach, our team
will collaborate with you to adjust the course to focus on your specific learning
objectives and goals.
