Is all made of expressions, so this may be the challenging part for those with programming backgrounds.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Who is DAX for?<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Any excel professional\/ user who works with power pivot and would like to leverage DAX to implement BI solutions in their workplace, own business etc.\u00a0\u00a0<\/li>\n<li>Power BI users that want to develop further their skills by having a better understanding of DAX formulas and implement them in their models.\u00a0\u00a0<\/li>\n<li>Anyone interested in business intelligence in order to solve common business questions and problems related to day to day work, reports and dashboards.\u00a0\u00a0<\/li>\n<li>Business analyst looking to improve tasks and reports that can be replaced with a data model in excel using Power Pivot and DAX expressions.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Learning DAX<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Be mindful that DAX sometimes looks easy, but you\u2019ll have to spend a few hours reading and understanding some new concepts before moving to practice.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Of course, you can quickly start writing formulas in DAX specially with Excel background, as there is a lot of resemblance in many expressions, but without the understanding of the DAX behavior, you may get unexpected results from your calculations.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>The Data model<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In a few words, a data model is a set of tables, linked by relationships. The simplest form of a data model is a single table. <br>To begin your journey of learning DAX, we really recommend going through some basic concepts on data models and relationships, this will help you get a solid base for all the power you\u2019ll get from DAX.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Where to Start?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If you are an excel pro user, chances are that you are already working with Power Pivot or at least heard of it, if you haven\u2019t, don\u2019t worry, you can also start taking advantage of the data revolution that Microsoft has brought to everybody.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Aside from some basic data modeling concepts, to get familiar with DAX we recommend starting by reading about:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Loading tables to the data model.<\/li>\n<li>The basic DAX syntax.<\/li>\n<li>Calculated columns.<\/li>\n<li>Evaluation context.<\/li>\n<li>Measures.<\/li>\n<li>Table calculations.<\/li>\n<li>Iterations.<\/li>\n<li>Context transitions.<\/li>\n<\/ul>\n\n\n\n<p class=\"has-text-align-left wp-block-paragraph\">If you want to check out some free material online, we think the intro course from the guys at SQLBI is very good, it is not very long but you\u2019ll get to see a little of what you can accomplish with
