    In this blog post I will be showing you how to use a toggle button in Power BI. A toggle button in Power BI allows users to quickly switch between two options. Our first step is to create a toggle button as Power BI doesn’t have one by default. You can import one but by creating it yourself, it gives you more control. Our toggle button is created by having two images of identical size over the top of each other and using bookmarks to flip…

  • Creating calendar tables with DAX using Power BI

    By Nick Edwards In this blog post we’ll take a quick look at creating a self-generating calendar table using DAX. Dates are important if we want to perform time intelligence reporting on our data i.e. yearly sales, monthly sales, weekly sales, year to date sales or previous year sales. We’ll be using the calendar function to create our date table, but there are other methods to do this such as CALENDARAUTO or GENERATESERIES. Here is the…

  • Using T-SQL Merge to load Data Warehouse dimensions

    In my last blog post I showed the basic concepts of using the T-SQL Merge statement, available in SQL Server 2008 onwards. In this post we’ll take it a step further and show how we can use it for loading data warehouse dimensions, and managing the SCD (slowly changing dimension) process.

  • Business Intelligence in the Cloud

    The Cloud is pretty much top of the list of the corporate buzzword bingo phrases at the moment. It's clear what the benefits are from a SAAS perspective, but it's been less clear how the Business Intelligence world will start to make use of it.

    Data Warehousing, Management Information, Cubes, Data Mining etc. all involve a lot of data, usually gigabytes or terrabytes even for medium sized organisations. Internet connectivity (speed and…

  • Data Warehousing: Kimball vs Inmon

    Anyone involved in the Business Intelligence space has had their head in the sand if they are not aware of the long running, and more often than not misunderstood, debate between the two conceptual models of data warehouse design. Bill Inmon has recently posted an article on www.b-eye-network.com discussing the matter, and to his credit, has tried to put forward a number of balanced pros and cons of each methodology.

  • Leap before you can land

    Leap before you can land… Research scientists at the Southern Illinois University have concluded that primitive frogs learned to jump before they learned to land. The result being a rather inelegant crash landing. I’m sure the frogs were happy that they achieved their goal of getting from A to B, but I do feel sorry for them having to endure the presumably painful landing, not to mention the indignity of having the rest of the pond witness…
