DAX (Data Analysis Expressions) is a formula language that helps you create new information from the data that already exists in your Data Model. DAX formulas enable you to perform data modelling, and data analysis and use the results for reporting and decision-making. It is a collection of functions, operators, and constants that can be used in a formula or expression to calculate and return one or more values. DAX is the formula language associated with the Data Model of Excel Power Pivot.

This app has been designed for all those readers who depend heavily on MS Excel to prepare charts, tables, and professional reports that involve complex data. It will help all those readers who use MS Excel regularly to analyze data. Professionals who use data modelling and data analysis for reporting and decision-making purposes will benefit from this.

This app is an extension to the Excel Power Pivot app, hence it is a good idea to brush up on the Excel Power Pivot app before you delve into DAX. Knowledge of Excel Functions and Excel Formulas is not necessary for this app, as DAX is entirely for the Data Model in the Power Pivot window.
