Power BI makes it easy to connect to data and start building reports. One thing that is often not thought of until late in the process is how the reports will be refreshed, and more importantly, what security context will be used for the refresh. When using the Power BI desktop application to get data the user is prompted to enter credentials for the data source. The user can select Windows Authentication, Database credentials, Microsoft Account, and others depending on the source. /2020/006-windows-meeting-tips/ Tue, 09 Jun 2020 12:49:15 -0500 /2020/006-windows-meeting-tips/ This month’s T-SQL Tuesday topic is hosted by Kenneth Fisher [b|t] and is Non-SQL Tips & Tricks. Given the rise in remote work and remote meetings, I would like to share some tips for having a professional meeting that includes screen-sharing. It does not matter if you are using Zoom, GoToMeeting, Microsoft Teams, or whatever Google is calling their meeting solution this week, these tips will help you to look like a pro to your team and clients. /2020/005-pbi-covid19-modeling-active-cases-with-advanced-dax/ Wed, 20 May 2020 08:00:00 +0000 /2020/005-pbi-covid19-modeling-active-cases-with-advanced-dax/ This is the fourth post in a series on building a Power BI report on the COVID-19 data. The source of the data is the COVID-19 Data Repository by the Center for Systems Science and Engineering (CSSE) at Johns Hopkins University. This post builds on the foundation from the previous steps. Part 1: Import COVID-19 Data with Power BI Part 2: Create a Star Schema with COVID-19 Data in Power BI Part 3: Create Simple Reports on COVID-19 Cases with Power BI] Part 4: Modeling Active COVID-19 Cases with Advanced DAX in Power BI (This Post) In the previous post we created a simple report on the COVID-19 time series data. /2020/004-pbi-covid19-simple-report/ Mon, 11 May 2020 08:00:00 +0000 /2020/004-pbi-covid19-simple-report/ This is the third post in a series on building a Power BI report on the COVID-19 data.

This data set is interesting for many reasons and I plan on using it in many examples here. Challenge The most accurate files in this repository are the time series files. These files have several descriptive columns (Country, Province, Latitude, Longitude) and then a column for each day starting at 2020-01-22 with the count of cases (confirmed, recovered, or deaths depending on the file) for that date. /2020/000-what-is-this-blog/ Mon, 04 May 2020 14:01:09 -0500 /2020/000-what-is-this-blog/ What is this blog? Most of the content here will be focused on Business Intelligence, SQL Server, and data. This blog is several things. External memory: A place to save things so that I can remember them later. Helping hand: A place to share content that others may find useful. Self learning: A forcing function for me to learn new technology.
