-------------------------------------------------------------------------------- /课本/第一章-绪论.md: -------------------------------------------------------------------------------- 1 | # 第一章 - 绪论 2 | 3 | ## 数据库系统概述 4 | 5 | ### 数据库的4个基本概念： 6 | 7 | 1. 数据：**描述事物的符号记录称为数据。**数据的含义成为数据的语义，数据与其语义是不可分割的。 8 | 2. 数据库：**数据库是长期存储在计算机内、有组织、可共享的大量数据的集合。**数据库中的数据按一定的数据模型组织、描述和存储，具有**较小的冗余度**、**较高的数据独立性**和**易扩展性**，并可为各种用户共享。 9 | 3. 数据库管理系统：**数据库管理系统是位于用户和操作系统之间的一层数据管理软件。**其主要功能有：**数据定义**、**数据操纵**、**数据库的运行管理**、**数据库的建立以及维护**等4个方面。 10 | 4. 数据库系统：**数据库系统是由数据库、数据库管理系统（及其应用开发工具）、应用程序和数据库管理员组成的存储、管理、处理和维护数据的系统。** 11 | 12 | 13 | ### 数据管理技术的产生和发展 14 | 15 | 1. **人工管理阶段** 16 | 2. **文件系统阶段** 17 | 3. **数据库系统阶段** 18 | 19 | ![](https://s1.ax2x.com/2018/06/01/7vs4N.png) 20 | 21 | ### 与人工管理相比，数据库系统的特点; 22 | 23 | 1. **数据结构化** 24 | 2. **数据共享度高，冗余度低且易扩充** 25 | 3. **数据独立性高：**数据独立性包括**物理独立性**和**逻辑独立性**。物理独立性是指**用户的应用程序与数据库中数据的物理存储是相互独立的**。逻辑独立性是指**用户的应用程序与数据库的逻辑结构是相互独立的**。 26 | 4. **数据由数据库管理系统统一管理控制：**数据管理系统提供以下数据控制功能：**数据的安全性保护**、**数据的完整性检查**、**并发控制**和**数据库恢复**。 27 | 28 | 29 | 30 | ## 数据模型 31 | 32 | 数据模型也是一种模型，他是对现实世界数据特征的抽象，是数据库系统的核心和基础。 33 | 34 | #### 两类数据模型： 35 | 36 | 1. 第一类是**概念模型** 37 | 2. 第二类是**逻辑模型和物理模型：**逻辑模型主要包括**层次模型、网状模型、关系模型、面向对象数据模型、对象关系数据模型、半结构化数据模型。**物理模型是对数据最底层的抽象。 38 | 39 | ![](https://s1.ax2x.com/2018/06/01/7yD9u.png) 40 | 41 | ### 概念模型 42 | 43 | #### 信息世界中的基本概念： 44 | 45 | 1. **实体：**客观存在并可相互区别的事物称为实体。 46 | 2. **属性：**实体具有的某一特征称为属性。 47 | 3. **码：**唯一标识尸体的属性集称为码。 48 | 4. **实体型：**用实体名及其属性名集合来抽象和刻画同类实体，称为实体型。 49 | 5. **域：**属性的取值范围。 50 | 6. **实体集：**同一类型实体的集合。 51 | 52 | #### 概念模型的表示方法： 53 | 54 | 表示方法很多，最常用的是**实体—联系**方法。该方法用**E-R**图来描述现实世界的概念模型。 55 | 56 | ### 数据模型： 57 | 58 | #### 三大组成要素： 59 | 60 | 数据模型通常由**数据结构、数据操作和数据的完整性约束条件**三部分组成。 61 | 62 | 1. 数据结构：描述数据库的组成对象以及对象之间的联系。 63 | 2. 数据操作：查询、更新。 64 | 3. 数据的完整性约束条件：一组完整性规则。 65 | 66 | #### 常用的数据模型： 67 | 68 | 1. 层次模型 69 | 2. 网状模型 70 | 3. 关系模型 71 | 72 | ### 关系模型： 73 | 74 | #### 关系模型的数据结构： 75 | 76 | 1. **关系：**一个关系对应常说的一张表。 77 | 2. **元组：**表中的一行。 78 | 3. **元数：**即属性 79 | 4. **属性：**表中的一列。 80 | 5. **码：**表中的某个属性组，它可以唯一确定一个元组。 81 | 6. **关系模式：**对关系的描述，一般表示为：**关系名（属性1，属性2，...，属性n）。** 82 | 83 | #### 关系的完整性约束条件： 84 | 85 | 关系的完整性约束条件分为三大类：**实体完整性，参照完整性和用户定义完整性。** 86 | 87 | 88 | 89 | ## 数据库系统的结构： 90 | 91 | ### 数据库系统模式的概念： 92 | 93 | 在数据库系统中有**型**和**值**的概念，如：（学号，姓名，性别，系别，年龄）这样的纪录是型，而（1607094128，解奕鹏，男，大数据学院，20）则是该记录型的一个记录值。 94 | 95 | **模式**是数据库中全体数据的逻辑结构和特征的描述，他仅仅设计型的描述。模式的一个具体的值称为模式的一个实例，同一个模式可以有很多的实例。 96 | 97 | ### 数据库系统的三级模式结构: 98 | 99 | 三级模式结构由**外模式，模式，内模式**三级构成。 100 | 101 | ![](https://s1.ax2x.com/2018/06/01/7yprB.png) 102 | 103 | #### 模式： 104 | 105 | 模式也称逻辑模式，是数据库中**全体数据的逻辑结构和特征的描述**，是所有用户的公共视图。**一个数据库只有一个模式。** 106 | 107 | #### 外模式（子模式）： 108 | 109 | 外模式也称**子模式或用户模式**，他是数据库用户能够看见和使用的**局部数据的逻辑挤乳沟和特征的描述**，是数据库用户的数据视图，是与某一应用有关的数据逻辑表示。**一个应用程序只能使用一个外模式。** 110 | 111 | #### 内模式： 112 | 113 | 内模式也称存储模式，一个数据库只有一个内模式。他是**数据物理结构和存储方式的描述**，是数据在数据库内部的组织方式。 114 | 115 | ### 数据库的二级映像功能和数据独立性： 116 | 117 | #### 外模式/模式映像： 118 | 119 | 当模式改变时**（如增加新的关系，新的属性，改变属性的数据类型等）**，由数据库管理人员对各个外模式/模式映像做相应改变，可以使外模式保持不变。应用程序是依据数据的外模式编写的，从而应用程序不必修改，保证了数据与程序的逻辑独立性，简称**数据的逻辑独立性。** 120 | 121 | #### 模式/内模式映像： 122 | 123 | 当数据库的存储结构改变时（**例如选用另一种存储结构**），由数据库管理人员对模式/内模式映像做相应改变，可以使模式保持不变，从而应用程序不必改变。保证了数据与程序之间的物理独立性，简称数据的物理独立性。 124 | 125 | 126 | 127 |

设R(U)是属性及U上的一个关系模式，X，Y是U的子集，若对于R(U)上的任意一个可能的关系r，r中不可能存在两个远足在X上的属性值相等，而在Y上的属性值不等，则称**X函数确定Y**或**Y函数依赖X**，记作X->Y。 19 | 20 | * 非平凡函数依赖：若X->Y，但Y不属于X。 21 | * 平凡函数依赖：若X->Y，Y属于X。 22 | * 决定因素：若X->Y，则X成为这个函数依赖的决定属性，也称决定因素 23 | * 若X->Y，Y->X，记作X<-->Y 24 | * 完全函数依赖：在R(U)中，若X->Y，并且对于X的任意一个真子集X'，都有X'不能确定Y，那么称Y对X完全函数依赖 25 | * 部分函数依赖： 26 | * 传递函数依赖：在R(U)中，若X->Y，Y不能确定X，Y->Z，那么称Z对X传递函数依赖 27 | 28 | ### 码 29 | 30 | > 码是关系模式中的一个重要概念。 31 | 32 | * 超码与候选码的关系：候选码是最小的超码 33 | 34 | #### 多值依赖 35 | 36 | > 设R(U)是属性集U上的一个关系模式，X，Y，Z是U的子集，且Z=U-X-Y。关系模式R(U)中多值依赖X->->Y成立，当且仅当对R(U)的任意一个关系r，给定一对（x，z）的值，有一组Y的值，这组值仅仅决定于X的值与Z值无关。 37 | 38 | #### 范式 39 | 40 | ![7l5kG.png](https://s1.ax2x.com/2018/06/03/7l5kG.png)

| ## 事务的基本概念 4 | 5 | ### 事务 6 | 7 | > 事务时用户定义的一个数据库操作序列，这些操作，要么全做，要么全不做，是一个不可分割的工作单位。 8 | 9 | #### 事物的ACID特性 10 | 11 | * 原子性：要么全做，要么全不做 12 | * 一致性：事务执行的结果必须是使数据库从一个一执行的结果变到另一个一致性状态 13 | * 隔离性：并发执行的事务之间不能互相干扰 14 | * 持续性：一个事务一旦提交，对数据库中数据的改变就是永久的 15 | 16 | 17 | 18 | ## 数据库的恢复概述 19 | 20 | > 把数据库从一个错误的状态恢复到某一个已知的正确的状态的功能，就叫数据库的恢复 21 | 22 | 23 | 24 | ## 故障的种类 25 | 26 | * 事务内部的故障-undo撤销 27 | * 系统故障-redo重做 28 | * 介质故障 29 | * 计算机病毒 30 | 31 | 32 | 33 | ## 恢复的实现技术 34 | 35 | ### 数据转储 36 | 37 | > 数据转储是数据库恢复中采用的基础技术，所谓转储就是数据库管理员定期将整个数据库复制到磁盘保存起来，这些备用的数据叫做后援副本或后备副本。 38 | 39 | ### 登记日志文件 40 | 41 | 两条原则： 42 | 43 | * 登记的次序严格按照并发事务执行的时间次序 44 | * 必须先写日志文件，再写数据库 45 | 46 | 47 | 48 | ## 恢复策略 49 | 50 | 51 | 52 | ## 具有检查点的恢复技术 53 | 54 | 55 | 56 | ## 数据库镜像 57 | 58 | > 介质故障是对系统映像最为严重的一种故障 59 | 60 | 61 | 62 | 63 | 64 | 65 | 66 | 67 | 68 | 69 | 70 | 71 | 72 | 73 | 74 | 75 | 76 | 77 | 78 | 79 | 80 | 81 | 82 | --------------------------------------------------------------------------------

**主要包括用户身份鉴别，多层存取控制，审计，视图和用户加密等** 12 | 13 | #### 用户身份鉴别 14 | 15 | 1. 静态口令鉴别 16 | 2. 动态口令鉴别 17 | 3. 生物特征鉴别 18 | 4. 智能卡鉴别 19 | 20 | #### 存取控制 21 | 22 | 1. 自主存取控制 23 | 24 | > 用户对于不同的数据库对象有不同的存取权限，不同的用户对同一个数据库对象也有不通过的权限，而且用户可以将自己拥有的权限授权给他人 25 | 26 | 2. 强制存取控制 27 | 28 | > 每个数据库对象都有一个密级，每个用户也都被授予一个级别的许可证，只有合法的许可证才可以存取。 29 | 30 | 3. 授权：授予与回收 31 | 32 | * grant 33 | 34 | ```java 35 | grant <权限> 36 | on <对象> 37 | to 38 | with grant option; 39 | ``` 40 | 41 | * revoke 42 | 43 | ```java 44 | revoke <权限> 45 | on <对象> 46 | from 47 | ``` 48 | 49 | #### 数据库角色 50 | 51 | 1. 角色的创建 52 | 53 | ```java 54 | create role <角色名> 55 | ``` 56 | 57 | 2. 给角色授权 58 | 3. 角色权限的收回 59 | 60 | 61 | 62 | ## 视图机制 63 | 64 | ## 审计 65 | 66 | **审计功能吧用户对数据库的所有操作自动记录到审计日志中** 67 | 68 | 69 | 70 | ## 数据加密
