2022年12月9日 · In SQL Server 2019 CU5, a class of DAX functions first introduced for tabular models informally known as SuperDAX are now enabled for multidimensional models. While some existing DAX query patterns may need to be redesigned, SuperDAX functions provide significant improvements to query performance.

2019年12月30日 · We will release a new version of DAX Patterns. We started working on it in 2019 and we will complete the work in 2020. All the existing patterns will be refreshed with Power BI examples, more optimized DAX code, and we will also add new patterns.

It is meant to give you a quick and easy introduction on how you can use Data Analysis Expressions (DAX) to solve a number of basic data modeling and analytical problems. This topic includes conceptual information, a series of tasks you can complete, and a few quizzes to test what you’ve learned.

dax 是公式或表达式中可用来计算并返回一个或多个值的函数、运算符和常量的集合。 简而言之，dax 可帮助您通过模型中已有的数据创建新信息。 为何 dax 如此重要？ 创建工作簿并向其中导入一些数据的过程很轻松。
