Implement business intelligence, data modeling, and data analytics within Microsoft products such as Power BI, SQL Server, and Excel.
- Learn the in-and-out of DAX expressions and querying functions using easy-to-follow examples
- Manipulate different complexity of data and optimize BI workflows to extract key insights
- Create, monitor, and improve the performance of models by writing clean and robust DAX queries
DAX provides an extra edge by extracting key information from the data that is already present in your model. With this book, you will leverage DAX’s functionality and flexibility in the business intelligence and data analytics domain.
You’ll start from the basics of DAX, along with the importance of good data models, and how to write efficient DAX formulas by using variables and good formatting. You will understand how DAX queries work using an example-based approach. You will learn to optimize the BI workflow by writing efficient and powerful DAX queries with easy-to-follow explanations and examples. You will learn to manipulate and load different complexity of data within various Microsoft’s products like Power BI, SQL Server, and Excel Power Pivot. You will learn to build and extend your data models to gain additional insights. Later you will delve into progressive DAX syntax and functions to understand complex relationships in DAX. You will cover important DAX functions, specifically those related to tables, date and time, filtering, and statistics. You will then move on to more progressive topics such as how the formula and storage engines work to be able to optimize your queries.
By the end of this book, you will be able to employ DAX to enhance your data model by extracting new information and gaining deeper insights.
