**SAS Base 认证精炼：举例教学** 本课程旨在帮助学员掌握 SAS Base 认证所需的核心知识，该认证包含两项考试：SAS 9.4 编程基础以及 SAS 9.4 Base 编程。SAS 认证考试近年来的重点已从纯粹的语法记忆转向考察学员的应用能力，通常会提供示例数据集和问题，要求学员在有限的指导下进行数据操作。 本课程的教学理念是“理解优先，死记硬背靠后”。针对每个知识点，我们将深入探讨其“是什么”（用途）、“如何用”（操作方法）、“为什么”（针对不同问题类型的选项、优劣势及局限性）以及“何时用”（在数据管理流程中的应用阶段）。 课程内容按照数据管理员或分析师完成任务的预期步骤组织： 1. **数据读取：** 学习如何根据数据源的不同，选择合适的数据读取工具。 2. **数据准备：** 掌握数据分析前的准备工作。 3. **数据管理/分析：** 学习数据管理和分析的关键步骤。 总之，课程致力于让学员对每个关键知识点都具备情境化的理解，明确如何以及何时使用。课程还包含大量的练习，贯穿于每个课程单元的前后。
In this course, you will learn the most essential notions that are covered under SAS Base Certification. The base certification is organized into two exams: (1) Programming Fundamentals Using SAS 9.4 and (2) Base Programming Using SAS 9.4. SAS certification exams have evolved in recent years to focus more on testing students ability to implement the notions learned. Typically, example data sets are given, questions are asked; then students are expected to answer those questions by manipulating the data with limited instructions. In the past, exams were mostly memory-based; they were designed to test students ability to remember the syntax and the rules of programming language. We designed this course to focus more on comprehension over memory; specifically, for each notion covered, we try to answer the "WHAT"-what is it used for, "HOW"- how is it used, "WHY"- for each type of question, options available, strengths and, limitations, and "WHEN"-at what stage of data management stage is it used. The course is organized along the line of the expected steps a data manager or analyst needs to take to complete his/her task: (1) How to read the data? what tools are available for that purpose depending on the data source; (2) How to prepare the data prior analysis; (3) data management/analysis step. In short, for each essential notion we try to ensure that you have a contextual understanding of it: how to and when to use it. We also included a lot practice exercises, before and after each lesson.
