Coursera 课程“掌握 DAX 基础:Power BI、Power Pivot 和 SSAS”是一门实践导向的课程,旨在帮助学习者轻松掌握数据分析与数据建模。DAX(Data Analysis eXpressions)是一种强大的表达式语言,可广泛应用于 Power BI、Power Pivot 和 Analysis Services。 课程共分为三个主要部分: 第一部分:**常用 DAX 表达式入门**。本节将介绍 SUM、SUMX、COUNT、ROUND、DIVIDE、MIN、MAX、IF 语句、文本表达式、变量等最常用的 DAX 表达式。 第二部分:**DAX 工作原理详解**。本节将深入探讨 DAX 的核心概念,包括行上下文(Row context)和筛选上下文(Filter context),并讲解 ALL、FILTER、RELATEDTABLE、CALCULATE、EARLIER 以及关系(Relationships)等关键函数和概念。这部分理论与实践相结合,对于理解 DAX 的运作至关重要。 第三部分:**时间智能与日期表**。本节将学习时间智能函数,如 TOTALYTD、SAMEPERIODLASTYEAR、DATESADD、DATESBETWEEN、CALENDERAUTO 等,并通过 CALCULATE 函数探索这些函数的工作方式。 贯穿整个课程,**每一部分都包含实践活动**。课程强调,掌握 DAX 的关键在于大量的实践练习。
Data Analysis and data modelling made easy with Data Analysis eXpressions. DAX can be used in Power BI, Power Pivot and Analysis Services. Analyse and Model your data with in Power BI, Excels Power Pivot and Analysis Services with Data Analysis eXpressions. This is a hands on course Course Overview In the first section of this course you will be introduced to the use of the most common DAX expressions, such as SUM and SUMX, COUNT, ROUND, DIVIDE, MIN, MAX, IF Statements, TEXT expressions, Variables and More In the next section of this course you will learn the fundamentals of how DAX works. This section will include both theory and examples and it is of utmost importance that you understand how DAX works. We will discuss Row context and Filter context, ALL, FILTER, RELATEDTABLE, CALCULATE, EARLIER, Relationships and much more. In the third section of this course you will learn about Time Intelligence and Date Tables. We will look at expressions such as TOTALYTD, SAMEPERIODLASTYEAR, DATESADD, DATESBETWEEN, CALENDERAUTO, and we will explore how many of these functions work using CALCULATE Each section of this course contains Activities to complete. These Activities are of utmost importance. When it comes to learning DAX, practice is a must.
