书籍：数据库系统原理与设计(第3版)——万常选 廖国琼等编著

任务驱动：由于找不到原始数据库,只有从零开始创建数据库、设计数据库关系图、输入数据，为后面深入研究数据库做好数据准备。

数据库版本：SQL Server 2005

操作步骤：

1.创建数据库源码如下或是通过数据库管理工具创建数据库

USE [master]

GO

/****** 对象:  Database [ScoreDB]    脚本日期: 11/28/2018 21:44:34 ******/

CREATE DATABASE [ScoreDB] ON  PRIMARY 

( NAME = N'ScoreDB', FILENAME = N'D:\Program Files (x86)\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\ScoreDB.mdf' , SIZE = 3072KB , MAXSIZE = UNLIMITED, FILEGROWTH = 1024KB )

 LOG ON 

( NAME = N'ScoreDB_log', FILENAME = N'D:\Program Files (x86)\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\ScoreDB_log.ldf' , SIZE = 1024KB , MAXSIZE = 2048GB , FILEGROWTH = 10%)

 COLLATE Chinese_PRC_CI_AS

GO

EXEC dbo.sp_dbcmptlevel @dbname=N'ScoreDB', @new_cmptlevel=90

GO

IF (1 = FULLTEXTSERVICEPROPERTY('IsFullTextInstalled'))

begin

EXEC [ScoreDB].[dbo].[sp_fulltext_database] @action = 'disable'

end

2.创建表源码如下或是通过数据库管理工具创建表

SET ANSI_NULLS ON

GO

SET QUOTED_IDENTIFIER ON

GO

IF NOT EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[Class]') AND type in (N'U'))

BEGIN

CREATE TABLE [dbo].[Class](

[classNo] [char](6) NOT NULL,

[className] [varchar](30) NULL,

[institute] [varchar](30) NULL,

[grade] [smallint] NULL,

[classNum] [tinyint] NULL,

 CONSTRAINT [PK_Class] PRIMARY KEY CLUSTERED 

(

[classNo] ASC

)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]

) ON [PRIMARY]

END

GO

SET ANSI_NULLS ON

GO

SET QUOTED_IDENTIFIER ON

GO

IF NOT EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[Course]') AND type in (N'U'))

BEGIN

CREATE TABLE [dbo].[Course](

[courseNo] [char](3) NOT NULL,

[courseName] [varchar](30) NULL,

[creditHour] [numeric](18, 0) NULL,

GO

SET ANSI_NULLS ON

GO

SET QUOTED_IDENTIFIER ON

GO

END

GO

IF NOT EXISTS (SELECT * FROM sys.foreign_keys WHERE object_id = OBJECT_ID(N'[dbo].[FK_Course_Course]') AND parent_object_id = OBJECT_ID(N'[dbo].[Course]'))

ALTER TABLE [dbo].[Course]  WITH CHECK ADD  CONSTRAINT [FK_Course_Course] FOREIGN KEY([priorCourse])

REFERENCES [dbo].[Course] ([courseNo])

GO

ALTER TABLE [dbo].[Course] CHECK CONSTRAINT [FK_Course_Course]

GO

IF NOT EXISTS (SELECT * FROM sys.foreign_keys WHERE object_id = OBJECT_ID(N'[dbo].[FK_Score_Course]') AND parent_object_id = OBJECT_ID(N'[dbo].[Score]'))

ALTER TABLE [dbo].[Score]  WITH CHECK ADD  CONSTRAINT [FK_Score_Course] FOREIGN KEY([courseNo])

REFERENCES [dbo].[Course] ([courseNo])

GO

ALTER TABLE [dbo].[Student]  WITH CHECK ADD  CONSTRAINT [FK_Student_Class] FOREIGN KEY([classNo])

REFERENCES [dbo].[Class] ([classNo])

GO

ALTER TABLE [dbo].[Student] CHECK CONSTRAINT [FK_Student_Class]

3.设计数据库关系图

实战经验：建立主键与外键关系时，两者数据类型必须一致。
