DAX for the SQL developer
Learning DAX can be tricky, especially if you have a background in SQL.
DAX Gotchas
The FILTER function does not create a new filter context but a row context. The ROW function is executed in a filter context without creating a row context. To demystify this and all the other DAX Gotchas that I bumped into is the goal of my session.
Debugging common DAX and Model performance issues
In this session, we will explore real world DAX and Model performance scenario's. These scenarios range from memory pressure to high CPU load. Watch as we will dive into the model and improve performance by going through concrete examples.
DAX Best Practices
Best bractices in DAX formulas from real world experience.
DAX Optimization Examples
In this session we analyze some DAX expressions and Tabular models and, through the usage of DAX Studio and some understanding of the VertiPaq model, we will look at how to optimize them.
DirectQuery in Power BI and Analysis Services
DirectQuery best practices in Analysis Services and Power BI
Understanding the Power BI data model
In this session we will look at all the important topics that are needed to get your Power BI modelling skills to the next level. We will cover the in memory engine, relationships, DAX filter context, DAX vs M and DirectQuery.
Impact of weather on English Premier League in Power BI
By using open data and web scraping in Power BI we will examine if weather has an impact on games in the English Premier League. We will look at the advantages and disadvantages of using open data and web page data how Power BI works with it.
Handling Relationships in DAX
Tabular offers only one-to-many relationships on a single column: it seems poor when compared with Multidimensional. However, with DAX, you can handle any relationship. We analyze and solve scenarios with calculated, virtual and complex many-to-many.
An introduction to the Power BI Designer
In this session we will look in detail into some of the features for the Power BI designer and take it for a spin and investigating some of the new capabilities it has to offer for different relationships and new DAX formulas.
Budgeting with Power Pivot
Alberto will show you some common techniques to use when building a budget model with Power Pivot and Power Query, including previous year allocation, multiple-step budgeting with linked back tables, handling of budget on non-existing products
Using PowerBI and DAX to predict and win Fantasy F1
Using PowerQuery, PowerPivot, PowerView and DAX to model, analyse and win a Fantasy Formula 1 league. Guarantee yourself eternal glory as a braniac petrol head, and become a PowerBI and DAX pro in the process.
Advanced Modeling with Analysis Services Tabular
This session goes beyond the classical star schema modeling, exploring new techniques to model data with Power Pivot and SSAS Tabular. You will see how brute-force power in DAX allows different data models than those used in SSAS Multidimensional
DAX Patterns
Learn ready-to-use DAX patterns improving development speed of Power Pivot solutions. Good also for SSAS Tabular developers.
Optimizing & Analyzing DAX Query Plans
Alberto will start with a simple query and he will perform on stage all the necessary steps to optimize it, showing you the tools ant the techniques used to identify the bottleneck and to fix the performance issues
DAX Query Engine Internals
In this session, we will analyze the way DAX solves filtering. Starting from simple queries, we will follow the steps DAX does with the filter context, discovering the internals of the query engine of DAX.
DAXMD: SSAS Multidimensional meets DAX and Power View
This session looks at the most significant new functionality to be added to SSAS Multidimensional in recent years: support for the DAX language and Power View.
MDX vs. DAX: Currency Conversion Faceoff
Compare and contrast how multidimensional and tabular achieve the same end result in quite different ways. Features covered can be used in a broad range of scenarios (not only currency conversion), adding valuable knowledge to your SSAS arsenal.
BI from space: PowerPivot with NASA data
In this session, you will learn how to combine data from web services, tables and cubes to build a powerful model, and visualise it in Excel.
Time Intelligence in DAX
We are going to show how to compute classical time intelligence with the built-in DAX functions. Then, we will show some more complex time intelligence formulas that require to think out of the box, using advanced data modeling techniques.
