1、关于数据库课程
->数据库概念：数据库的基本操作，基本T-SQL
->Ado.Net操作数据库：C#代码访问数据库的技术
->数据库高级内容：文件组，数据库权限系统，高级SQL应用，面试题目等
->课程共7天课，前两天T-SQL基础，后面三天Ado.Net 最后两天 数据库高级
2、数据库的概念
->数据库就是数据仓库。
->DBMS:数据库管理系统。SQLServer Oracle
3、数据库的特点
->安全性
->并发访问处理
->高效率
->海量数据存储
->数据完整性
4、数据库的基本组成
->数据库
->架构（表的分组）
->表
->列（Column字段，类型，长度，约束等）
->行（Row）
->主键：自动增长，GUID
->外键
5、数据库管理
->数据库安装
->数据库的实例名详解：区分安装在同一台机器上不同的MSSqlServer 服务的。
->混合身份验证：Windows身份验证、SQLServer身份验证
->启用SA账户（安装的时候可以直接设置启用）
->链接数据库：
->保证SQLServer服务器开启
->. 和 （local) 和 机器名一样，代表链接本机。
->ip地址：
->回环地址：127.0.0.1
->局域网ip地址，外网ip地址。
->SA
6、可视化创建数据库、表、主键
->创建数据库
->数据库文件默认位置：C:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\DATA\
（创建数据库最好放到此位置，避免权限问题。）
->表
->命名规范同类。
->列：
NChar,Nvarchar(32) N:Unicode，2个字节表示一个字符。
Char：一个字节表示一个字符。
->可能遇到的问题：“阻止保存要求重新创建表的更改”的问题，解决办法： 工具→选项→设计器→阻止表的更改
->主键：
7、数据库的字段类型详解
8、案例：创建School数据库
9、数据库的迁移方案
->分离 附加
->权限问题：
->启用Administrator账号
->把数据库文件放到默认的数据库文件存放目录。
->数据库文件兼容级别，设置成2005兼容
->脱机 附加
->备份 还原
->生成SQL脚本
10、SQL脚本
->结构化查询语言（Structured Query Language）
->DML\DDL\DCL ->脚本：一般就是指比较简单的，不需要编译的可以直接解析执行的语言，常见的比如：SQL、JavaScript等
->T-SQL的特点
->跨DBMS，基本上所有的DBMS都对标准T-SQL兼容 ->大小写不敏感（仅仅是关键字不敏感，字符串数据是大小写敏感的）
->转义
->php
11、基本的DDL SQL脚本
->创建数据库（Create Database）
->创建表（包括主键、自动增长、是否可空）等
12、基本的DML SQL脚本
->简单的查询： Select 列名 From 表明 where 条件表达式
->插入数据： Insert Into 表名（列名） values(列值)
->删除数据：Delete
->修改数据：Update
13、案例：OA系统数据库设计
部门表:Department JQJB:警情级别
->部门的名字 DepName
->部门的老大 DepMaster
->部门的编号 主键：
->部门的描述
->删除标识
->上级部门的ID
select * from dep where ParentDepId =我的id
员工表、
内部员工消息表
->发送者
->发送的时间
->发送的内容
->接收
->接收时间
...

14、约束
15、最牛的注释：就是没有注释。
使用CREATE 语句创建索引 CREATE INDEX index_name ON table_name(column_name,column_name) include(score) 普通索引 CREATE UNIQUE INDEX index_name ON table_name (column_name) ; 非空索引 CREATE PRIMARY KEY INDEX index_name ON table_name (column_name) ; 主键索引 使用ALTER TABLE语句创建索引 alter table table_name add index index_name (column_list) ; alter table table_name add unique (column_list) ; alter table table_name add primary key (column_list) ; 删除索引 drop index index_name on table_name ; alter table table_name drop index index_name ; alter table table_name drop primary key ;
