  • What Can Fabric Do For My Lake?

    March 13, 2024 / No Comments »

    Previously, I discussed the pros and cons of Microsoft Fabric OneLake and Lakehouse. But what if you have a data lake already? Will Fabric add any value, especially if your organization is on Power BI Premium and you get Fabric features for free (that is, assuming you are not overloading your capacity resources)? Well, it depends. Managed Area A Fabric lakehouse defines two areas: managed and unmanaged. The managed area (Tables folder) is exclusively for Delta/Parquet tables. If you have your own data lake with Delta/Parquet files, such as Databricks delta lake, you can create shortcuts to these files or folders located in ADLS Gen 2 or Amazon S3. Consequently, the Fabric lakehouse would automatically register these shortcuts as tables. Life is good in the managed area. Shortcuts to Delta/Parquet tables open interesting possibilities for data virtualization, such as: Your users can use the Lakehouse SQL Analytics endpoint to join...

  • Make a Pledge and Trouble is at Hand: Microsoft AI and Fabric Copilots

    March 11, 2024 / No Comments »

    Rounding up the wisdom from the inscriptions of the Apollo Temple (see the Nothing in Excess and Know Thyself posts), the last known famous inscription was "Make a pledge and trouble is at hand." Although the original intention was lost in time, it's believed that this inscription instructs us to understand our limits so we don't overpromise. Fast forward to modern data analytics, I remember how Microsoft Power BI started less than 10 years ago with the grand promise to democratize BI to the masses. One would believe that AI would be an essential ingredient to fulfill that promise. To its credit, Power BI includes various built-in and useful ML features, such as Analyze Increase/Decrease (my favorite), Decomposition Tree, Key Influencers, Get Insights, and Q&A. It's surprising to me though that Fabric copilots are an ultra premium feature as they require at least P1 or its Fabric equivalent of F64...

  • A First Look at DAX Visual Calculations: the Good, the Bad, and the Ugly

    February 28, 2024 / No Comments »

    The February 2024 release of Power BI Desktop includes a preview of visual calculations. As its name suggests, a visual calculation is a visual-scoped DAX measure that works at the aggregate (visual) level. The Good Visual calculations make previously difficult tasks much easier. Consider the following matrix: Suppose you need a measure that calculates the difference between the product categories in the order they were sorted in the visual. Implementing this as a regular DAX measure is a challenge. Yet, if we had a way to work with the cells in the visual, we can easily find a way to get this to work. Ideally, this would work similar in Excel, but DAX doesn’t know about relative references. However, visual calculations do (kind of). Let’s right-click on the visual and select “New calculation”. In the visual-level DAX formula bar, enter the following formula: Category Diff = [Sum of SalesAmount] -...

  • Nothing in Excess: Deciphering Data Architectures by James Serra

    February 9, 2024 / No Comments »

    In my last post, I talked about the lessons learned from the ancient Greeks. The second inscription on the temple of Apollo in Delphi was "Nothing in Excess." Yet, inspired to be modern and embracing vendor's propaganda, it's my experience that companies tend to overdo their data architectures. I talked about this in this newsletter. Another excellent resource that could help you strike a balance is the James Serra's latest book "Deciphering Data Architectures." I was privileged to know James Serra for a while, have him multiple times present to our Atlanta BI Group, and be an early reviewer of this book. Besides consolidating the wealth of information from his excellent blog, James took a vendor-neutral approach to various patterns. Each pattern describes the architecture followed by pros and cons analysis. After all, the right architecture and "best practice" is what works for you given your specific circumstances and restrictions....

  • Know Thyself: Power BI Source Control

    February 8, 2024 / No Comments »

    Last year my wife and I did a tour of Greece, and we had a blast. Greece, of course, is the place to go if you are interested in ancient history and the origin of democracy. One of the places we visited was Delphi. The ancient Greeks believed it to be the center of the universe. Now not much was left of it except lots of ruins and imagination. But back then it was magnificent. People from all over the world would come to consult with the Oracle of Delphi. She delivered her prophecies from the temple of Apollo, which had three inscriptions, with one of them being "Know thyself". The practical benefit for the oracle was that if you believed her cryptic prophecy wasn't fulfilled then your interpretation was wrong. Therefore, the problem was in you because you didn't know yourself. How does this translate into BI? I see...

  • SSRS Going on 20

    January 24, 2024 / No Comments »

    Last year around this time, I went to Antarctica on an expedition ship. Although I got my fair share of icebergs, whales, and penguins, I found it interesting to reproduce some of the experience of the first explorers. On our way back, we got it pretty rough crossing the Drake passage. 80% of the passengers succumbed to sea sickness. There was a huge swell during the night. The next day the captain told us that we faced some 10-meter waves. It felt like a bad roller coaster ride. Yet, the explorers did it. On wooden ships with no stabilizers and communication. Not knowing where they were going and with a high probability that they won’t survive! What does this have to do BI? The remote connection is that 20 years ago a small group from Microsoft was set up to create a new reporting tool that was code-named “Rosetta” and...
