At the end of this training, you will be able to write complex DAX expressions for your analytics need, and put them all together to build the best model for your data analysis solution using Power BI.
The training includes but is not limited to the topics below:
4.1: Introduction to DAX
DAX is an abbreviated name for Data Analysis eXpression language. This is the expression language in Power BI for analytics. DAX is a dynamic expression language that will consider the interaction of the user at the time of visualization. Using DAX, you can do calculations such as year to date, year over year comparison, etc. Most of the data modeling training is about DAX. In this section, you will learn the basics of DAX.
- Syntax of DAX
- Naming in DAX
- Operators and Operands

- Calculated Column; Row by Row
- Measure; Single Output
- Calculated Table; A derived table
- Calculated Column? Maybe a good candidate for Power Query transformation
- Measures are Dynamic
4.3: Aggregation and Iterator Functions
The first set of important functions in DAX are aggregation functions. There is a set of normal aggregation functions such as SUM, MIN, MAX, and there is another set called iterators.

4.4: Filter Functions
Filter functions are probably the most important functions in DAX. You can refer to a column in DAX (like Excel), but you cannot refer to rows. If you want to refer to rows in an expression, you must filter it, and that is why Filter functions are important. There are several filter functions, and the behavior of all of them is unique. In this section, we will talk about some of these functions through real-world examples.
- Filter Functions to be used inside other functions
- Examples of using ALL function
- ALL and SUMX; Percentage Calculation
- Filter Function: Custom Filter
- Values/Distinct; getting a unique list of values
4.5: Evaluation Contexts and Conditional Sum
Understanding Evaluation contexts are one of the most critical learnings in DAX. The evaluation context refers to the way that filters impact the calculation’s result in DAX. There are two types of contexts; Row context, and filter context. In this section, you will learn about the difference between all these, and you will learn scenarios that you need to be careful of when the context changes.
- Row Context
- Filter Context
- Exception for Row Context
- Exception for Filter Context
- Calculate Function
- Conditional Sum; Three ways of Implementing; pros and Cons
- Variables in DAX and using them for debugging
4.6: Relationship Functions
Some of the functions in DAX are going through directions of relationship and apply some filtering based on that, like RELATED() for example. Some other functions change the behavior of relationships such as the UseRelationship() function. In this section, you will learn about relationship functions in DAX and scenarios of using them.
- Related: Many to one
- RelatedTable: Sub table that can be used as a filter
- CrossFilter: Changing Direction of relationship
- UseRelationship: using an inactive relationship
- TreatAS function
4.7: Time Intelligence Functions
Calculations based on time and date are critical for many businesses such as finance. You can use DAX to do calculations such as year to date, fiscal year to date, year over year comparison, and rolling 12 months average. In this section, you will learn some basic time intelligence functions such as TotalYTD to a calculated year to date.

In this section, you will learn about parent-child functions which can be used for organization hierarchy. You will learn different scenarios of using these functions in real-world examples.
- Organizational Hierarchy or Chart of Accounts: unknown levels
- Path function
- PathLength: getting the number of levels
- PathItem: finding a specific level
- PathContains: Security Pattern
- LookupValue: To get the other related fields
4.10: Best Practices Tips and Tricks
Performance considerations when doing the modeling in Power BI is the last but not least important part of this course.

Module 5: Power BI Design Patterns – 1-day course
Power BI Design patterns are a set of architectural designs of the dimensional models combined with Power Query techniques and DAX calculations that are designed for solving a business case scenario. The technique of a design pattern can be applied with minimal changes to similar patterns in other scenarios. An example of a design pattern is a subscription system. As a data analyst, you like to know the count of active subscribers at any given date. A model designed for this practice with the DAX calculations can be useful for a ticketing system too. Because you will likely want to know how many open and closed tickets you have on any given date. This training module is recommended for anyone building Power BI data models.
This course includes but is not limited to the design patterns above;
- What are design patterns and how to use them
- Customer retention
- Inventory stock on-hand
- Age-based analysis
- Static banding or binning
- Dynamic banding or binning
- Budget Vs. Actual
Module 6: Power BI for Data Architects (Architecture and Administration) – 1-day course
This training is designed for a data architect or administrator, who is designing the architecture of leveraging Power BI in a solution. Someone who wants to understand how all components of Power BI are sitting beside each other to build the whole solution. This training is designed for understanding the strategy of using Power BI rather than its development.
In this training, you will learn about architecting the strategy of a Power BI solution from end to end. This is not training about development (Modules 1 to 3 already covered that). You do not need to attend previous modules to attend this course. This course is designed separately from those. However, knowing some of the basics of Power BI is helpful.
You will learn about Power BI Service, and different types of connections in Power BI and choose the right type of connection for your solution. You will also learn all the different ways of sharing a Power BI Solution and the pros and cons of each. The course continues with a detailed discussion about row-level security. You will learn how gateway configuration and setup will be in the whole package. You will also learn about integrating Power BI with other tools, and some architecture blueprints to follow when you are designing a Power BI solution.
At the end of this training, you will be able to design the architecture of Power BI for your requirement; you can choose the right way of sharing and design the gateway configuration as well as the communication of Power BI with other tools and services. You will be able to answer any questions that come to your mind about a solution architecture in the Power BI world and make the right decision to choose the right strategy of Power BI usage in your organization.
The training includes but is not limited to the topics below:
6.1: Power BI Service
Power BI service or website plays an important role in designing a Power BI solution. Power BI website is the hosting environment for Power BI reports, dashboards, and datasets. In this section, you will learn about these objects and their configuration. You will also learn about the different types of connections in Power BI, and the position of the gateway in the solution, configuring and installing it.

- Workspaces in Power BI; Dev Environment
- Power BI Apps; User Environment
- Publish to Web
- Embed in SharePoint Online; Office 365 Integrated Sharing
- Power BI Embedded; Embedding content into another application
- Comparison of all Sharing methods
Sharing is about giving users access to the entire content; security is about giving them access to part of it. There are different ways of implementing security (which is called row-level security in Power BI). Statics row-level security is a good option when roles are limited items. The next level is to define a dynamic row-level security using DAX functions. Dynamic row-level security comes as different patterns which will be discussed here through examples.
- Row Level Security
- Dynamic Row Level Security
- Patterns for Dynamic Row Level Security
- Manager Level Access
- Organization Chart Access as Dynamic Row Level Security

Why Power BI Training?
Power BI is the newest Microsoft BI tool for data mash up, build modeling, and visualize it effectively. It supports mobile devices, it supports self-service, and along with its great functionalities, it doesn’t require heavy development or production system.
Common Myths about Power BI
There are some myths about Power BI that sometimes prevents people and organization to move towards using this product. We’ve listed some of the myths in the following. Please note that these are Myths, and they are not the right assumptions.
Myth 1: Power BI is a self-service Excel tool, and isn’t suitable for Enterprise Solutions.
There are many scenarios that Power BI that has been used in enterprise solutions. Power BI features for data mash-up (with the very powerful data transformation component: Power Query), and data modeling based on xVelocity in-memory engine (Based on SQL Server Analysis Services Tabular Engine), and great data visualization components, along with mobility support of this product, are rarely available in other products. We have designed, implemented, and have seemed many BI enterprise solutions based on Power BI within very large organizations.
Myth 2: Power BI is easy to use, and doesn’t require a training course.
Power BI is an easy-to-use tool, but for basic functions. Every BI application requires calculated measure, which needs to be written in DAX. Every BI application requires advanced data transformations which need to be handled with Power Query M scripting language. Designing and implementing solutions with Best Practices is always a requirement for reliable BI applications. We designed our Power BI training in a way that delivers advanced content for all components of Power BI and fortifies your team’s knowledge of the product, so they can solve any complex challenge with this tool.
Myth 3: Power BI is only for Microsoft based environments and platforms.
Power Query is the core of data extraction in Power BI. Power Query supports a wide range of data sources. Not only SQL Server, but also Oracle, MySQL, web service result set, DB2, and many other data sources are supported. There is also the possibility to connect to many systems such as Salesforce. The Visualization component of Power BI is also HTML5 supported and is available for all mobile devices. Power BI app in AppStore, and Google PlayStore, as well as Microsoft AppStore, enables dashboards and data visualizations to be available in all environments.
Myth 4: Power BI is not a powerful and fully functional BI tool, and cannot be compared with other tools in the market.
In fact, the reverse is true. Power BI is such powerful that can be the replacement of many other expensive BI tools in the market. We’ve been through scenarios of successful Power BI solutions that have been a replacement of Cognos, IBM products, Oracle WB, SAP BO, and so on. Power BI has 5 powerful components that cover the main aspects of BI and the data analysis system.
In addition, there is always the possibility to use this as a hybrid approach and save lots of time and money along with great features that are only available in this product.
What others say about our training and trainers (Testimonials)
Stefan Küppers, Business Process Owner BI / SCI, Logistics
Together with two colleagues of mine I joined Module 2 & 3 of the “Power BI from Rookie to Rock – Star” Training in Duisburg, Germany. The in-person training hold by Reza was just fantastic. In a well-structured way Reza not only gave a comprehensive overview but also deep dived into the functionalities of PowerBI and showed us the great value this software could bring to enterprises. I can strongly recommend the sessions and hope to get the chance to attend other courses as well. Thanks a lot to Reza and team!
Donna MacKenzie – Senior Revenue Analyst Massey University
The workshop run by Reza and Leila was amongst the best I’ve ever done. The pace was just right. Their prepared materials were superb. I really enjoyed the hands on nature of their training. I learned so much in a short time. I came back to my desk and felt confident enough to start building my own reports.
I would definitely sign up for their training again!
Brent Gamble – Team leader BI Training and Support Massey University
We organised a 4 day training event with Reza and Leila from Radacad.
From the outset they provided great advice on what they could cover and provided a very comprehensive overview for the 25 trainees attending the training. For anyone who is considering PowerBI specifically and want clarity on the best architecture and how to effectively use PowerBI, I strongly recommend contacting Radacad.They gave us a real head start.
Thanks Reza and Leila.
Daniel Kastelic – Otago Regional Council
Easily the finest quality course I’ve ever attended in my life. Reza knows PowerBI inside out and it really showed in the extent of topics covered. He was also willing to show me an example on real life data application, and offered further help via email enquiries in the future. Well worth the money and time invested, as PowerBI is definitely the future of Business reporting.
Jamie Yim – Senior Business Analyst Enterprise Process
I attended RADACADs “Power BI from Rookie to Rock – Star” course in Auckland from 19-23 Nov 2018. I had a beginner’s knowledge of Power BI, and found the course extremely helpful in understanding what could be done within Power BI. Reza was an excellent instructor, and explained concepts and methods in a clear and concise manner. There were lots of practical examples and exercises provided as part of the course, and Reza was also very helpful and willing to answer any questions we had about improving our existing Power BI reports and dashboards. A very enjoyable course – I highly recommended it.
I have been using Power BI for around 1 year and I was in love with it the very first day. It was very easy to visualize and bring our data stories to the client’s presentations. During my initial days, I had to use web search or use the Microsoft Power BI forums to find answers to my questions and to explore the tool. On many such occasions, I found Reza’s blog and articles to my rescue. I finally decided to attend the 5 day Power BI : Rookie to Rockstar Course.
Right from the Day 1 through Day 5, Reza was a professional and a pleasant instructor. He is very approachable and very much flexible even though I was attending the Online Course from United States. The classroom was LIVE from New Zealand. Very thorough in covering all the details mentioned in the curriculum and there was no Question that he could not answer. His expertise and knowledge are second to none. I have learnt a lot with the sessions especially data modeling and DAX functions which I would definitely put to use in the near future at my current job. I would like to thank Reza and his team for the flawless and wonderful sessions. It was very informative.
Daniel R Tuma, Senior Systems Analyst at Cleveland Metro Schools, Ohio, USA
I spent probably about two weeks looking for a good Microsoft Power BI class that would cover all of the aspects of the program. I wanted to walk away from the class being able to apply what I learned immediately. Most training companies that I looked into were in a state of flux with Power BI mostly due to the transitions that Power BI itself was going through. Then I stumbled on the RADACAD web site. Reza Rad touted a course that he taught named “Power BI, From Rookie to Rock star.” If the class was indeed an A to Z course, then it was exactly what I was looking for. The class outline seemed to include every topic on my checkoff list plus much more. I decided to give Reza a try.
Reza completely lived up to his hype. He took us through a natural progression of the software, using example after example of how to complete a task. We went through real world scenarios, a bare minimum of two scenarios for each minor topic. I was completely impressed with his Power BI knowledge, understanding and abilities. Any question we came to Reza with was answered completely and with even more examples.
After the class, my goal of immediately applying what I learned was attained. Right away I was able to successfully pull and massage data, create useful reports and post them to dashboards.
I would recommend Radacad Power BI Training without hesitation.
Jeffrey Weir; Independent Consultant, Wellington, New Zealand
I learned a lot from this course: it gave a great overview of what’s possible both right from the UI, and what more awaits if you lift the hood and pimp the engine. It’s incredible to see just how much PowerBI and PowerQuery radically simplify what I would otherwise have to do with many, many lines of complicated VBA code. And Reza is a masterful user of this tool.
Note that Reza covers a lot of ground in this course, and it is pretty fast paced. While you can take a laptop and follow along as Reza takes PowerBI/Powerquery through its paces, for the one-day course my recommendation would be to keep that laptop closed, and simply sit back and watch Reza in action, so you can fully concentrate on just how simple this tool is to use in the right hands as well as think about how you might use the tool to your own ends and ask questions along those lines. You can always purchase the video course (if it’s not already included in your course) and step through the material again at your own pace.
Rob Wilby; Independent Consultant, UK
I must say your “Power BI Essentials” course has been the most comprehensive Power BI course I have found to date and seeing how you work with data especially the little tricks naturally introduced at just the right moments has made this course a pleasure to take.
Martin Catherall – Data Platform MVP, PASS Regional Mentor
I attended Reza’s Power BI pre-con “From Rookie to Rock star” at SQL Saturday Brisbane in May 2016. I was a complete Power BI novice, having only previously accomplished a few very basic things with Power BI. Reza took the group through all the components that make up environment. He explained how they had evolved and took the group through walk-throughs of each one. Reza was great an answering questions from the audience at the event and going into extra detail if necessary. All-in all, I would say that I’m now a very confident Power BI user after attending Reza’s pre-con.
Dan Cheshire, Senior Project Manager Air New Zealand
Reza does not just know Power BI like the back of his hand, he is the most commercially aware BI person I know. He understands that companies work in the real world and that data isn’t always clean and needs manipulation for it to work and be useful. When Reza worked on our project, nothing phased or flustered him, he always came up with solutions for problems that seemed to me as insurmountable. Can’t recommend him enough, invest in Reza as he will not only save you a whole heap of time, but he comes up with long lasting and very powerful Power BI solutions for your business.
Sonia Buckley, Data Analyst at Zoom2u, Sydney, Australia
We have started to use Microsoft Power BI and whilst Microsoft tutorials are helpful, if you are not used to DAX then it is very difficult to get your head around and there is little other resources that don’t cost an arm and a leg. I had a call with Reza who made my life so much easier in just under an hour! Any time spent speaking to Reza will be well worth it – I have saved hours of trying to get my head around our dashboards by getting some very useful tips and explanations on why things are done the DAX way! Not only that but he is very patient and straight forward. Highly recommended!
R. Kemp, Canada
The course was an excellent investment overall, it exceed my expectations. It was well paced and presented. The instructor, Reza Rad, was excellent and was able to answer all my questions and explain complex idea in a manner that was easy to understand and follow. I had been using Power BI Desktop for a number of months prior to taking this course, but wish I had attended it sooner! The course structure of 1 day of overall Power BI and followed by 4 days of more intensive instruction on the various parts of Power BI allowed for a basic understanding of the whole, and then more comprehensive learning. The live-on-line experience worked well technically and allowed for questions and problem-solving with the instructor. I learned a lot about Power BI and this course gave me a great foundation for using Power BI to clean, model, design, and share reports using a variety of visualizations that will provide business intelligence to my company. I would recommend this course to anyone wanting to learn Power BI either as a starting point or even after you have used the tool to deepen your understanding and build your skill-set.
