Course NT-PowerBI Using Power BI Desktop, Power BI Service, DAX, and Power Query as Business intelligence tools

This course is not the only course in our training center dedicated to business intelligence tools, but we suggest visiting it first of all.

The fact is that Power BI Desktop uses a component called Power Query to receive and transform data. For professional reporting, the ability to work with this component is necessary.

Power BI Desktop uses DAX, a language, to provide advanced business computing. For professional reporting, the ability to create expressions in this language is also required.

This course covers both Power Query and DAX, but not separately from Power BI Desktop, but in close connection with it and with each other, thus providing the most complete amount of knowledge, skills and abilities to work with BI tools from Microsoft.

After completing this course, students will be able to:
  • Master the hottest BI tool - Power BI Desktop.
  • Embrace the data culture. Master the principles of building data models, distributing data into tables (and tables into fields), plan relationships between tables and configure these relationships, and much more.
  • Learn how to load data from different sources (text files, Excel workbooks, databases, web pages, Google spreadsheets, Share Point lists, various cloud storages, etc.) and link them together to form a data model.
  • You will be able to carry out a step-by-step transformation of this data, with the help of which “bad” data can be brought to a form that will allow further use of this data.
  • Learn how to extend the data model by creating so-called data models in DAX. calculated fields and measures.
  • Learn how to visualize your data by creating interactive, visually appealing, informative and user-friendly reports.
  • Learn how to use the Power BI cloud service to collaborate on reports.
Audience Profile

The audience for this course is very broad. It is an absolute must visit for every data scientist who wants to learn how to use the most powerful tools of the Power BI platform for analysis.

Before attending this course, students must have:
  • Experience in Windows, Office. Good skills in Excel (sorting and filtering data, subtotals, smart tables, pivot tables, charts, VLOOKUP - required). Experience in Access or any other relational DBMS preferred.

Important! Power BI Desktop uses Power Query to retrieve and transform data. In our opinion, it is better to study Power Query in the Excel environment, and then consider the differences between the Excel environment and the Power BI Desktop environment. Therefore, this unit is included in this training, and we will use Excel to study it.
