**课程名称：** Microsoft Access for Beginners **课程概述：** 本课程面向初学者，旨在介绍 Microsoft Access 数据库管理系统。Microsoft Access 将关系型数据库引擎与图形用户界面和软件开发工具相结合，是 Microsoft 365 套件的一部分。 课程重点在于 **结构化查询语言 (SQL)**。SQL 是一种计算机语言，用于从数据库中检索数据，其语法类似于英语，易于理解和使用。掌握 SQL 有助于创建更有效的查询，并能更轻松地诊断和修复不返回预期结果的查询。 SQL 是一种处理事实集及其之间关系的高效语言。Microsoft Office Access 等关系型数据库程序使用 SQL 进行数据操作。SQL 作为一种国际标准，被 ISO 和 ANSI 等标准机构认可。 通过学习 SQL，您将能够描述数据集，从而有效地回答各种问题。课程将强调正确使用 SQL 语法的重要性，语法是语言中正确组合元素的规则集。
Microsoft Access is a database management system from Microsoft that combines the relational Access Database Engine with a graphical user interface and software-development tools. It is a member of the Microsoft 365 suite of applications, included in the Professional and higher editions or sold separately.When you want to retrieve data from a database, you ask for the data by using Structured Query Language, or SQL. SQL is a computer language that closely resembles English, but that database programs understand. Every query that you run uses SQL behind the scenes. Understanding how SQL works can help you create better queries, and can make it easier for you to understand how to fix a query that is not returning the results that you want.SQL is a computer language for working with sets of facts and the relationships between them. Relational database programs, such as Microsoft Office Access, use SQL to work with data. Unlike many computer languages, SQL is not difficult to read and understand, even for a novice. Like many computer languages, SQL is an international standard that is recognized by standards bodies such as ISO and ANSI.You use SQL to describe sets of data that can help you answer questions. When you use SQL, you must use the correct syntax. Syntax is the set of rules by which the elements of a language are correctly combined.
