This past week I ran into an interesting challenge with a client. The data warehouse is capturing testing data for an educational institution. In the screenshot below, you’ll see Continue reading Data Warehouse Design Challenge: Relating a Temporal Fact Table to a Date Dimension
A couple weeks ago in a recent update to Power BI, an enhancement was added to enable a drill-down action in Power BI. This has been something that customers have been clamoring for but now its finally here!
Not all visualizations can be used to invoke the drill-down action. Here are the visualizations that you can use the drill-down action in Power BI: Continue reading Drill Down with Power BI Visualizations
SQL Saturday #442 in Orlando, FL has come and gone but what a turn out! The event was excellent, we had a great turnout for our session and had a blast! And as a bonus, the BBQ lunch, baked beans, coleslaw, mac n cheese and dessert were amazing. Seriously one of the best lunches I’ve had a SQL Saturday event! Plus, the Lego name tags were epic! 100% without a doubt the coolest name tag ever.
October 4th of this month was my seven year anniversary as an employee of Pragmatic Works. Things have changed a lot over the past seven years. Working with the wonderful people at Pragmatic Works has been quite an amazing journey and incredible opportunity. With that in mind I thought that I should share my story of how I ended up working in the business intelligence field with the great team at Pragmatic Works. Continue reading How I Got my Start at Pragmatic Works
SQL Saturday #442 is upon us and yours truly will be presenting in Orlando, Florida on October 10th alongside Mitchell Pearson (b|t). The session is scheduled at 10:35 AM and will last until 11:35 AM. I’m very excited to be presenting at SQL Saturday Orlando this year as it’ll be my first presenting this session in person and my first time speaking at SQL Saturday Orlando! If you haven’t registered yet for this event, you need to do that. This event will be top notch!
My session is called Designing a Data Warehouse from the Ground Up. What if you could approach any business process in your organization and quickly design an effective and optimal dimensional model using a standardized step-by-step method? In this session I’ll discuss the steps required to design a unified dimensional model that is optimized for reporting and follows widely accepted best practices. We’ll also discuss how the design of our dimensional model affects a SQL Server Analysis Services solution and how the choices we make during the data warehouse design phase can make or break our SSAS cubes. You may remember that I did this session a while back for Pragmatic Works via webinar. I’ll be doing the same session at SQL Saturday Orlando but on-prem! ;)
So get signed up for this event now! It’s only 11 days away!
This week I’m teaching the Pragmatic Works Intro to MDX virtual training class. A student in the class asked how they could find the current day sales amount using MDX (no SSAS functionality) and I thought this was a worthy blog topic. This solution assumes that the cube is processed at least once a day as the query you’re about to see returns the last day in the cube that we data for.
The first part is where the most work takes place. I created a named set to identify
One of the current issues in Power BI is the inability to specify a Date table. The Date table is what enables us to create some of the powerful DAX time calculations like Year To Date, Month To Date and more when the Date key is not a Date data type. Ginger Grant has blogged about this issue with a proposed work around, which you can read about here. Even though we can’t exactly specify which table is our Date table in Power BI, that doesn’t mean we can’t create some nifty time calculations with Continue reading Creating Time Calculations in Power BI
