课程名称：数据库管理系统卓越：模块4 课程概述： 本模块专注于数据库管理系统（DBMS）的核心概念，特别是ACID原则及其在DBMS中的重要性。课程内容涵盖以下要点： 1. ACID的全称及其四个基本特性：原子性（Atomicity）、一致性（Consistency）、隔离性（Isolation）和持久性（Durability）。 2. 了解ACID属性对数据库管理系统的重要性及其在事务管理中的作用。 3. 探讨DBMS的基本组成部分及其硬件需求。 4. 识别与DBMS交互的三类用户角色。 5. 学习数据库访问语言（Database Access Language）的概念及其功能。 6. 了解关系数据库模型的提出者及其基础理念。 7. 深入研究关系模型的关键概念和组件。 8. 分析关系模型的多种优点。 9. 明确主键（Primary Key）、外键（Foreign Key）和复合键（Composite Key）的定义及其特性。 10. 讨论主键的空值与不允许空值的原因，以及表中是否可以存在多个外键，并探讨主键在其他表中作为外键的使用情况。 通过本课程的学习，学员将对数据库管理系统的基本原理和结构有深入的理解，为数据库的设计与管理打下坚实的基础。
