It was fine but a basic level. I thought it could be an advanced level course. Would be great if there is advance level course using the APIs, Creating the Dataflows, merging the dataflows and so on.
Data needs to be transformed and reshaped to meet our reporting needs. This process is called data modeling and one of the best ways to perform it is with Power Query. Power Query is a data preparation and transformation engine, originally introduced as an Excel 2010 add-on. It is widely available within Microsoft products, such as Power BI, Excel, Azure, and Dataverse. Power Query connects to multiple data sources, including SQL DB, Rest API, csv, JSON, Google Analytics, Web, etc. It provides the same user experience and data transformations regardless of the source. In this course, you will learn how to use Power Query to perform data modeling to prepare your data for analysis with BI tools like Power BI.
Learn how to use Power Query to perform the essential Extract, Transform, and Load (ETL) tasks necessary to process data from different sources. Then, you can use that data in Microsoft Azure, Microsoft Excel, Microsoft Power Bi, etc.
We will cover some of the most common data transformations inside Power Query, such as importing data from multiple sources, replacing and extracting values, merging columns, and removing columns and duplicates. You will also learn all about filters, date functions, conditional columns, pivoting and unpivoting, merging tables, parameters, query properties, data profiling, web scraping, and mathematical functions.
Data comes in all sizes, shapes, and forms. By default, it is often disorganized, difficult to analyze, and may contain information that is not required for our reporting needs. This is why we need to perform data modeling to transform and reshape our data.
“Data needs to be reshaped before it is ready for reporting. This is why Power Query is so powerful. It provides a guided user interface and is so easy for users to interact, shape, and transform their data—it’s literally done within a click of a button.”
