SQLBI+ is a subscription service that offers exclusive access to advanced content on DAX, Power BI, and Analysis Services, created by top experts Alberto Ferrari and Marco Russo.
This subscription is not a replacement for our other, foundational courses: it is an additional service for professional model authors who spend considerable time creating and deploying Tabular models in Power BI and Analysis Services.
Structured courses, white papers, and individual sessions are the primary formats you can find on SQLBI+. The topics are diverse and very specialized.
We constantly add new content to SQLBI+; in fact we are committed to adding at least 2 new courses and 4 other pieces of content every year.
Learn more about the philosophy of SQLBI+ on this article.
What is included (so far)
9 lectures - 5 hours The Composite Models video course describes in depth how Power BI and Analysis Services manage the different types of composite models you can create. The goal is to understand the underlying architecture to make sure you make the right design choices to create models that can be maintained over time and provide good performance to your end users.
26 lectures - 4 hours Learn how to use calculation groups and how they work internally. This course is a deep dive into calculation groups in DAX.
Learn how to use the new DAX window functions (INDEX, OFFSET, and WINDOW) to manipulate tables by sorting and partitioning data.
52 lectures - 7 hours The Writing DAX Queries video course describes the DAX query syntax and many DAX functions and techniques to manipulate data. These same techniques are also useful for creating DAX table expressions in calculated tables and in the Detail Rows Expressions in the Tabular model.
The composite models in Power BI introduced a new type of relationship cardinality called many-to-many. Nevertheless, despite their name, they are not many-to-many relationships: they are relationships between tables generated at different granularity. In this session, we clarify the purpose…
The VertiPaq engine used by SQL Server Analysis Services Tabular, Power BI, and Power Pivot, is a columnar database capable of incredible performances, both in speed and compression. In this session, we perform a deep dive into the database architecture…
Calculation groups are the most important feature introduced in DAX after variables in 2015. By using calculation groups, you can apply transformations to existing measures without having to create new measures in the model. For example, you can define the…
DAX provides a set of functions (Time Intelligence) to compute aggregations and comparisons over a range of dates: Year-To-Date, Same-Period-Last-Year, Moving Average, and so on. The DAX time intelligence functions can work well with a month granularity, but they have…
You created a wonderful Power BI report, but you wait too much time when you open it. Changing a slicer selection is also slow. Where should you start analyzing the problem? What can you do to optimize performance? This session…
Every Power BI model has dates and the need for calculation over dates to aggregate and compare data, like Year-To-Date, Same-Period-Last-Year, Moving Average, and so on. Quick measures and standard time intelligence functions in DAX can help, but how do…
