Microsoft Professional Program for Data Science and Artificial Intelligence

In the years 2017 to 2019 Microsoft provided several professional education programs, and named them “Microsoft Professional Program for …”. I took part in the programs for Data Science and Artificial Intelligence, which had some overlap. The programs were set up as online courses through EDX, an online university. There were about 12 courses for each program. Typically you would need from one to four weeks per course, so overall it took nearly 2 years for me to do this besides my normal work.

Power BI Search

In the top menu or using the following link https://www.mmertens.eu/power-bi-search, you reach a customized google search engine. It mainly works by defining the websites in which the search happens, rather than searching the whole internet. In this case, I loaded the URLs of the Power BI / SQL / Azure blogs into the customized engine. I know many good blogs, I did some research to find more, and I especially looked at the profiles of all 364 (as of July 2022) Microsoft Most Valuable Professionals (MVPs) for Data Platform – and added their blogs if they had one. I added some documentation sites like the Microsoft documentation, but also dax.guide or the Tabular Editor documentation.

AdventureWorksDW20xx / Which version to use?

AdventureWorks is one of the standard demo models from Microsoft for SQL Server. There is a data warehouse version (DW), an OLTP and a light OLTP (LT) version. They are versioned according to the SQL Server (on premises) version schema, which is basically the year (there used to be a 2008R2, but this naming schema wasn’t used any more). So the latest version of the datawarehouse (and I’m not interested in OLTP) is AdventureWorksDW2019. Now the confusion starts.

Azure Role Based Certifications for Data

Back in 2019, Microsoft introduced a new model for their certifications, called “role-based certifications”. The old certifications like MCSE (Microsoft Certified Solution Expert) and MCSA (Microsoft Certified Solution Associate) are gone. Also the Microsoft Professional Programs (they were not so well known) are gone. Have a look at this blog entry if you want to read about data certifications and the professional program in the past: https://www.mmertens.eu/2018/08/microsoft-data-certifications/

Udacity or Coursera for Azure Machine Learning Certificates?

In this blog post I compare the Udacity and the Coursera platform using one example, an Azure Machine Learning degree.Both platforms have the concept of putting courses together in a bigger context and therefore a more important certificate. It is called “Nanodegree” at Udacity, and “Professional Certificate” at Coursera. (Advertisement) https://www.coursera.org/professional-certificates/azure-data-scientisthttps://www.udacity.com/course/machine-learning-engineer-for-microsoft-azure-nanodegree–nd00333 In this special case a third certification comes into place: Microsoft Certified: Azure Data Scientist Associate. The required exam has the number DP-100. https://docs.microsoft.com/en-us/learn/certifications/azure-data-scientist/ Actually the Coursera certificate is very much oriented to prepare for the Microsoft exam. The Udacity certificate is not so strictly following the necessary skill list from Microsoft, but still Udacity writes “This Nanodegree program will also help prepare students for Microsoft’s Exam DP-100: Designing and Implementing a Data Science Solution on Azure.”

Configuration of Power BI Premium Per User

At the end of the previous year (2020), the new licensing option “Power BI Premium per User was introduced. It started with the possibility to ask for “priority access” for tenants. This phase is over and now every tenant should have the possibility to use the license options. There are new tenant settings “Premium per user (preview)” and it seems to be a common mistake (according to questions in the Power BI Community) to expect these settings to be the place to “switch on” Premium per user. (I also made this mistake). Here are four steps that can be used to get Power BI Premium per user up and running:

Hype about DirectQuery for Power BI datasets and Azure Analysis Services

There is a big hype about a new feature Microsoft provided under the name “DirectQuery for Power BI datasets and Analysis Services”: James Serra: Huge Improvement Paul Turley: It is truly the Utopian dream; the Holy Grail! Marco Russo / Alberto Ferrari: A milestone I agree with most of what they are writing, also regarding the importance of these changes. BUT, there is one thing I don’t like: Analysis Services on premises, especially Analysis Services Multidimensional is left out!
