What is Dax?




Dax stands for Data Analysis Expressions. It is a formula language that allows you to perform calculations on data stored in tables or columns. Unlike Excel formulas, which operate on cell values, Dax formulas operate on entire columns or tables, and can filter, group, aggregate, or transform data in various ways.


Dax has many benefits for data analysis, such as:



  • It can handle complex calculations that are not possible or efficient with Excel formulas.



  • It can work with large datasets that exceed the limits of Excel worksheets.



  • It can create dynamic measures that update automatically based on user selections or filters.



  • It can leverage the relationships between tables to perform cross-table calculations.



  • It can use time intelligence functions to analyze data over time periods.



Dax is not only used in Excel, but also in other Microsoft products such as Power BI, SQL Server Analysis Services (SSAS), and Azure Analysis Services (AAS).


What is Powerpivot?




Powerpivot is an add-in for Excel that enables you to create data models in Excel. A data model is a collection of tables that are linked by relationships. A data model can store and process large amounts of data from various sources, such as databases, files, web pages, or online services.


Powerpivot has many benefits for data analysis, such as:



  • It can import and refresh data from multiple sources without affecting the performance of Excel.



  • It can compress and store data in memory, making it faster and more scalable than Excel worksheets.



  • It can create relationships between tables, enabling you to analyze data across different dimensions.



  • It can use Dax formulas to create calculated columns, measures, and tables that enhance your data model.



  • It can create pivot tables, charts, slicers, and timelines that interact with your data model.



Powerpivot is not only available in Excel, but also in other Microsoft products such as Power BI Desktop, SQL Server Data Tools (SSDT), and SharePoint.

You can check if the add-in is enabled by going to File > Options > Add-Ins > COM Add-Ins. If you see Powerpivot for Excel in the list, make sure it is checked. If you don't see it, you may need to download and install it from the Microsoft website.



Once you have installed Powerpivot, you will see a new tab called Powerpivot in the Excel ribbon. This is where you can access the Powerpivot window, where you can create and manage your data models.


How to create a data model with Powerpivot?




To create a data model with Powerpivot, you need to follow these steps:



  • Import data from one or more sources. You can do this by clicking on the Home tab in the Powerpivot window, and then clicking on Get External Data. You can choose from various sources, such as databases, files, web pages, or online services. You can also import data from existing Excel worksheets or tables by clicking on Add to Data Model in the Data tab in the Excel ribbon.



  • Link data from different sources. You can do this by creating relationships between tables in your data model. You can do this by clicking on the Diagram View button in the Home tab in the Powerpivot window, and then dragging and dropping the fields that you want to link from one table to another. You can also create relationships by clicking on the Design tab in the Powerpivot window, and then clicking on Create Relationship.



  • Refresh data from your sources. You can do this by clicking on the Home tab in the Powerpivot window, and then clicking on Refresh All. This will update your data model with any changes that have occurred in your sources since the last import. You can also schedule automatic refreshes by clicking on the Design tab in the Powerpivot window, and then clicking on Table Properties.

You can do this by clicking on the PivotTable button in the Home tab in the Powerpivot window, and then choosing where you want to place your pivot table or chart. You can also use the Insert tab in the Excel ribbon to insert slicers and timelines that interact with your pivot table or chart.


How to write Dax formulas in Powerpivot?




To write Dax formulas in Powerpivot, you need to follow these steps:



How to write Dax formulas in Powerpivot?




To write Dax formulas in Powerpivot, you need to follow these steps:



  • Create calculated columns, measures, or tables. You can do this by clicking on the Data View button in the Home tab in the Powerpivot window, and then selecting the table where you want to add your calculation. You can then click on any empty cell in the table and type your formula in the formula bar. Alternatively, you can click on the Calculations tab in the Powerpivot window, and then click on New Column, New Measure, or New Table.



  • Use Dax syntax and operators. You can write Dax formulas using a similar syntax and operators as Excel formulas. For example, you can use arithmetic operators (+, -, *, /), comparison operators (=, , , =), logical operators (AND, OR, NOT), text operators (&), and parentheses (()). However, there are some differences and limitations that you need to be aware of. For example, you cannot use cell references (A1, B2) or range references (A1:B2) in Dax formulas. Instead, you need to use table names and column names (Table1[Column1], Table2[Column2]). You also cannot use array formulas or volatile functions (RAND, TODAY) in Dax formulas.



  • Use Dax functions and arguments. You can use Dax functions to perform various calculations on your data. Dax functions are similar to Excel functions, but they have some differences and limitations as well. For example, some Excel functions are not available in Dax (SUMIF, VLOOKUP), while some Dax functions are not available in Excel (CALCULATE, FILTER). You also need to use different arguments for some functions. For example, the SUM function in Excel can take a range of cells as an argument (SUM(A1:A10)), while the SUM function in Dax can only take a column or an expression as an argument (SUM(Table1[Column1]), SUM(Table1[Column1] + Table2[Column2])). You can find a list of all the Dax functions and their syntax on the Microsoft website.



Once you have written your Dax formulas in Powerpivot, you can use them to create calculated fields or values in your pivot tables or charts. You can do this by dragging and dropping your calculated columns or measures from the Fields list to the Values area or the Rows/Columns/Filters area.


How to use Dax functions in Powerpivot?
