That being said, learning DAX will open up a new world of Power BI for you. The most import feature you will unlock is being able to select, join, filter,… data in a dynamic way. This means that the dashboard can take input from the users and use it to dynamically generate calculated columns, measures and tables.
There are several DAX aggregation functions, such as SUM, COUNT, MIN, MAX, DISTINCTCOUNT, etc. that you can use in DAX formulas. It doesn’t take a lot of experience to reach a point where you are cursing at your screen, because your dashboard does not give you the results you expected.

The better you get at DAX, the smarter you can make your dashboard. By using DAX you can create smarter calculated columns and/or measures by which you can limit the data the dashboard has to fetch and visualise. Even though some DAX expressions can test the limits of the data engines, a well written expression can speed things up, thereby limiting the usage of resources. For some other ways to speed up your dashboard without using DAX, you can read these 5 tips I shared a couple of months ago. However, you always need to start with learning how the expression language works itself. What operators can be used, and what are the very simple basics of writing a DAX expression.

Power Pivot window also has a formula bar that is like Excel window formula bar. Formula bar makes it easier to create and edit formulas, using the AutoComplete functionality so as to minimize syntax errors. You can create a DAX formula for a calculated field either in the Excel window or in the Power Pivot window. In the case of calculated field, you need to provide the name beforehand.

You may think that such artifices would only add to their bewilderment, but I’m told that they calm and reassure the residents. “Football is a lot of work, but wrestling is like ….

Establishing referential integrity involves building a set of rules to preserve the defined relationships between tables when you enter or delete data. If you do not exclusively ensure this, as Power Pivot does not enforce it, you might not get correct results with the DAX formulas created before data changes are made.
