Introduction to Microsoft Excel Power Query, Data Model, Power Pivot and DAX
This course introduces Microsoft Excel’s powerful data modeling and business intelligence tools: Power Query, Power Pivot, and Data Analysis Expressions (DAX).
Business intelligence (BI) is a collection of tools and processes that are used to gather data and turn it into meaningful information that people can use to make better decisions.
You’ll get to have hands-on experience with Power Query; a tool that extract, cleanse, transform, and load data from flat files, folders, databases and more. You’ll practice shaping, blending and exploring the project files, and create completely automated loading procedures with only a few clicks.
Next, you’ll explore the Data Modeling and cover the fundamentals of database design and normalization (including table relationships, hierarchies and more). You’ll take a tour through Excel’s data model interface, and then create your own relational database to analyze throughout the course.
Next, you’ll use Power Pivot and DAX to explore and analyze the data model. Unlike traditional Pivot Table, Power Pivot allows you to analyze hundreds of millions of rows across multiple data tables, and create powerful calculated fields and measures using a formula language called Data Analysis Expressions (or “DAX” for short). You’ll learn basic DAX syntax, then introduce some of the most commonly-used and powerful functions like CALCULATE, FILTER, SUMX and more.
