Only Get the Last Few Periods of Data into Power BI using Power Query Filtering

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[…]

Get Images from Web Page Into the Power BI Report Using Power Query

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[…]

Conditional Column in Power BI using Power Query; You can do anything!

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![…]

Budget vs Actual: Zero Complexity Model in Power BI

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[…]

Create a Profiling Report in Power BI: Give the End User Information about the Data

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[…]

Build Your First Star Schema Model in Action: Power BI Modeling Basics

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[…]

Power BI Basics of Modeling: Star Schema and How to Build it

Now that you know about the dimension and fact tables, it is time to talk about one of the most important concepts of modeling. You might have heard about dimensional modeling or star schema, but you may have vague ideas about what it is, or alternatively, you might have used it, but not sure if Read more about Power BI Basics of Modeling: Star Schema and How to Build it[…]

Basics of Modeling in Power BI: Fact Tables

Fact tables are the core of analysis in a data model. In the previous article, I explained what a dimension table is, and why we cannot have everything in one big table. In this article, you will learn about the fact table, and how it positioned in a data model, you will also learn how Read more about Basics of Modeling in Power BI: Fact Tables[…]

Move Your Shared Tables to Dataflow; Build a Consistent Table in Power BI

I have written previously about the use cases of Dataflow in Power BI, and one of them was using one Power Query table in multiple Power BI reports. However, I that article just covered the surface, and I still see many solutions duplicating Power Query scripts in multiple files which brings a lot of inconsistency Read more about Move Your Shared Tables to Dataflow; Build a Consistent Table in Power BI[…]
