Power-Bi provides a power tool DAX functions, a formula language, that helps in manipulating the data and tables. It includes functions, operators, constants, and values to perform advanced calculations and queries on the tables and columns. Additionally, it assists in generating new information from the existing data. It is an all-encompassing service for data modeling and data analysis.

Since I am new to the Microsoft Power Bi tool, I often forget the syntax of DAX functions, and it is frustrating when this happens. The Power-Bi does provide inline suggestions for syntax nevertheless, it can be inconvenient because of its intricacy. I always prefer syntax in simple language, as making reports can sometimes be an exacting task because of its complexity. Moreover, I want DAX functions to be at my aid rather than making my analysis task strenuous.

Thus, I have prepared this cheat sheet so that I can always refer to it whenever I am stuck with the syntax. As I know what DAX function I want to use, but I often cannot recall the syntax. Hence, using the cheat sheet makes my activity more manageable.
