I have explained previously how you can use the Table.Profile Power Query function to fetch the profiling data of a table, such as minimum value, maximum value, null count etc, and use it in a report page to inform the user about the quality of the data. However, that function doesn’t provide you with one Read more about Get The Error Count with the Profiling Data of Power BI Data Table using Power Query[…]
There are always many questions about a cheat sheet to shows the existing capability for doing AI and ML in Power BI service and Desktop. In the above chart, I have summarized the capability of doing AI and ML in Power Service and Desktop for each role. I have identified three main roles in Read more about Overview of Available AI and ML capabilities in Power BI[…]
If you have been using T-SQL queries to build the tables of your Power BI data model, you probably know what I’m talking about. Sometimes after a while using a query in the Power BI model, you might change the script and want the change to be applied in the data model. One of the Read more about Change the T-SQL Script of a Power BI Table without Add/Remove from the Model[…]
I’ve been asked from one of my friends who were trying to create a random dataset for his presentation. There is a great and quick way that you can create a random list of numbers in Power BI using Power Query. In this short blog post, I’ll explain how to create this random list. You Read more about Generate Random List of Numbers in Power BI Dataset Using Power Query[…]
Power BI reports can get slow if you have huge amount of data. One of the ways to speed up the performance is to get the smaller part of the data, only the part that is needed for analysis. Most of the times, a date condition is a good filter for that. You might only Read more about Only Get the Last Few Periods of Data into Power BI using Power Query Filtering[…]
Power Query can connect to a web page and get data from there, and I have explained it before in my article about movies data analysis. However, the default way of getting data from the web page doesn’t fetch images into your report. Images in a webpage come through their own URL. If you can Read more about Get Images from Web Page Into the Power BI Report Using Power Query[…]
There are many scenarios that you might want to implement a conditional expression. When the conditional expression’s logic is on a row-by-row basis, the best is doing it in Power Query rather than DAX (there are exceptions always), The Add Conditional Column in Power Query is a very helpful option, but often many people find Read more about Conditional Column in Power BI using Power Query; You can do anything![…]
When I explain the Star Schema and best practices of data modeling in Power BI, Often I get questions such as what if we want to have budget and actuals in the same data model? what if there are two tables with different granularity? We cannot solve it with simple data modeling and relationships, this Read more about Budget vs Actual: Zero Complexity Model in Power BI[…]
Most of the time, you would like to know how the data quality looks like in your tables. Although, this is a process that you mainly check at the time of data preparation, having such report for end users, is also helpful, because sometimes they see an odd outcome, and wonder where this is coming Read more about Create a Profiling Report in Power BI: Give the End User Information about the Data[…]
Dimensions and Fact tables are the two essential parts of building a data model, and their relationship in the form of Star Schema is the best practice of doing the modeling. However, these are all theories until you really experience it in a real-world example. In this article, I want to put everything you learned Read more about Build Your First Star Schema Model in Action: Power BI Modeling Basics[…]
