![]() Syntax includes the various elements that make up a formula, or more simply, how the formula is written. Syntaxīefore you create your own formulas, let’s take a look at DAX formula syntax. Of course, there are other important concepts in DAX, but understanding these three concepts will provide the best foundation on which to build your DAX skills. We will frame DAX around three very important fundamental concepts: Syntax, Functions, and Context. Once you have the workbook downloaded onto your computer, open it, and then open the Power Pivot window. The examples and tasks here use the Contoso Sample DAX Formulas.xlsx workbook. The best way to learn DAX is to create some basic formulas, use it with some actual data, and see the results for yourself. You should also be familiar with the Power Pivot in Excel authoring environment and tools. You should already be familiar with fundamental concepts of both calculated columns and measures (also known as calculated fields), both of which are described in Power Pivot Help. We are going to focus specifically on understanding DAX formulas used in calculations. That knowledge will be helpful in understanding DAX, but even if you have no experience with Excel formulas, the concepts described here will help you get started creating DAX formulas and solving real-world BI problems right away. You might already be familiar with creating formulas in Microsoft Excel. This is Business Intelligence, and DAX will help you get there. When you get the information you need, you can begin to solve real business problems that affect your bottom line. Learning how to create effective DAX formulas will help you get the most out of your data.

This topic includes conceptual information, a series of tasks you can complete, and a few quizzes to test what you’ve learned. It is meant to give you a quick and easy introduction on how you can use Data Analysis Expressions (DAX) to solve a number of basic data modeling and analytical problems. This QuickStart is for users new to Power Pivot in Excel or tabular model projects authored in SQL Server Data Tools.
