Unlike Excel, DAX functions operate on data tables rather than individual cells. DAX allows for complex calculations and aggregations, making it essential for advanced data analysis in Power BI.<\/span><\/p>\n<h3 id=\"2-can-you-explain-the-concept-of-context-in-dax-and-its-relevance-in-power-bi\"><span class=\"ez-toc-section\" id=\"2_Can_you_explain_the_concept_of_context_in_DAX_and_its_relevance_in_Power_BI\"><\/span><b>2.
