Coursera 课程总结：Power BI Desktop 中的 DAX 基础 本课程旨在帮助您像专业人士一样运用 DAX（Data Analysis eXpressions）在 Power BI Desktop 中进行数据计算。DAX 是充分利用 Power BI 数据的关键，但许多用户发现其学习过程充满挑战，尤其是对于来自 Excel 和 SQL 背景的学习者。 课程将涵盖 DAX 的核心基础概念，包括： * **计算列与度量值**：理解两者之间的区别及其在 Power BI 中的应用。 * **求值上下文（Evaluation Context）**：掌握 DAX 计算的关键原理。 * **上下文转换（Context Transition）**：理解上下文如何在 DAX 函数中传递和改变。 * **虚拟表（Virtual Tables）**：学习如何创建和使用虚拟表来支持更复杂的计算。 * **变量（Variables）**：如何使用变量来提高 DAX 代码的可读性和效率。 * **时间智能函数（Time Intelligence Calculations）**：运用 DAX 进行时间相关的分析，如同比、环比等。 DAX 是一种独特的编程语言，与 Excel 和 SQL 不同，其计算过程发生在后台，这使得理解和掌握更为困难。本课程的目标是帮助您跨越这些学习障碍，克服常见的误区，从而自信地进行 DAX 计算。 如果您准备深入学习 DAX 语言，那么加入《Power BI Desktop 中的 DAX 基础》课程将是您的理想选择。
This DAX Basics in Power BI Desktop course will teach you how to perform DAX calculations like a pro. You will learn the difference between calculated columns and measures, evaluation context, context transition, virtual tables, variables, time intelligence calculations, etc.DAX in Power BI Desktop can be scary, but it shouldn't be that way. Data Analysis eXpressions (DAX) knowledge is critical to take full advantage of data in Power BI. Trying to master DAX without learning the basics is a mistake I have seen Power BI developers make very often. If you want to master DAX, learning the basic key concepts is a must.DAX in Power BI Desktop is a unique programming language and it's easy to give up if you are not committed to learning it. Most users find DAX difficult to understand. This is true, especially for users with a background in Excel and SQL. In Excel and SQL you can see how the formulas/queries work; whereas, in DAX everything happens behind the scenes. Therefore, in this course, one of my goals is to teach you how to overcome the common pitfalls and face DAX calculations with confidence moving forward.If you are ready to dive deeper into the DAX language, this is the time to join my DAX Basics in Power BI Desktop course.See you in class!
