Tableau is a standalone tool that can connect to numerous data sources. Tableau excels in handling complicated data for large corporations, whereas Power BI is easier to use and better suited for small and medium-sized businesses.

    DAX?

    Microsoft Excel and Power BI rely on a language called Data Analysis Expressions (DAX) to generate one-of-a-kind calculations and summaries used in data modeling and reporting. Like Excel formulas, it can instantly collect relational data. Calculated columns, tables, and metrics can be produced with ease using data analysis tools like DAX.

    Power BI Filters?

    Dashboards and reports can be masked from view using Power BI filters. They have the option to include or exclude data from certain columns in a dataset. There are basic, relative, and sophisticated filters available in Power BI. Complex criteria can be applied to images, pages, and reports by combining many filters.
