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
GO
ALTER DATABASE [ScoreDB] SET ANSI_NULL_DEFAULT OFF
GO
ALTER DATABASE [ScoreDB] SET ANSI_NULLS OFF
GO
ALTER DATABASE [ScoreDB] SET ANSI_PADDING OFF
GO
ALTER DATABASE [ScoreDB] SET ANSI_WARNINGS OFF
GO
ALTER DATABASE [ScoreDB] SET ARITHABORT OFF
GO
ALTER DATABASE [ScoreDB] SET AUTO_CLOSE OFF
GO
ALTER DATABASE [ScoreDB] SET AUTO_CREATE_STATISTICS ON
GO
ALTER DATABASE [ScoreDB] SET AUTO_SHRINK OFF
GO
ALTER DATABASE [ScoreDB] SET AUTO_UPDATE_STATISTICS ON
GO
ALTER DATABASE [ScoreDB] SET CURSOR_CLOSE_ON_COMMIT OFF
GO
ALTER DATABASE [ScoreDB] SET CURSOR_DEFAULT GLOBAL
GO
ALTER DATABASE [ScoreDB] SET CONCAT_NULL_YIELDS_NULL OFF
GO
ALTER DATABASE [ScoreDB] SET NUMERIC_ROUNDABORT OFF
GO
ALTER DATABASE [ScoreDB] SET QUOTED_IDENTIFIER OFF
GO
ALTER DATABASE [ScoreDB] SET RECURSIVE_TRIGGERS OFF
GO
ALTER DATABASE [ScoreDB] SET ENABLE_BROKER
GO
ALTER DATABASE [ScoreDB] SET AUTO_UPDATE_STATISTICS_ASYNC OFF
GO
ALTER DATABASE [ScoreDB] SET DATE_CORRELATION_OPTIMIZATION OFF
GO
ALTER DATABASE [ScoreDB] SET TRUSTWORTHY OFF
GO
ALTER DATABASE [ScoreDB] SET ALLOW_SNAPSHOT_ISOLATION OFF
GO
ALTER DATABASE [ScoreDB] SET PARAMETERIZATION SIMPLE
GO
ALTER DATABASE [ScoreDB] SET READ_WRITE
GO
ALTER DATABASE [ScoreDB] SET RECOVERY FULL
GO
ALTER DATABASE [ScoreDB] SET MULTI_USER
GO
ALTER DATABASE [ScoreDB] SET PAGE_VERIFY CHECKSUM
GO
ALTER DATABASE [ScoreDB] SET DB_CHAINING OFF
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,
[courseHour] [int] NULL,
[priorCourse] [char](3) NULL,
CONSTRAINT [PK_Course] PRIMARY KEY CLUSTERED
(
[courseNo] 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].[Term]') AND type in (N'U'))
BEGIN
CREATE TABLE [dbo].[Term](
[termNo] [char](3) NOT NULL,
[termName] [varchar](30) NULL,
[remarks] [varchar](50) NULL,
CONSTRAINT [PK_Term] PRIMARY KEY CLUSTERED
(
[termNo] 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].[Score]') AND type in (N'U'))
BEGIN
CREATE TABLE [dbo].[Score](
[studentNo] [char](7) NOT NULL,
[courseNo] [char](3) NOT NULL,
[termNo] [char](3) NOT NULL,
[score] [numeric](18, 0) NULL,
CONSTRAINT [PK_Score] PRIMARY KEY CLUSTERED
(
[studentNo] ASC,
[courseNo] ASC,
[termNo] 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].[Student]') AND type in (N'U'))
BEGIN
CREATE TABLE [dbo].[Student](
[studentNo] [char](7) NOT NULL,
[studentName] [varchar](20) NULL,
[sex] [char](2) NULL,
[birthday] [datetime] NULL,
[native] [varchar](20) NULL,
[nation] [varchar](30) NULL,
[classNo] [char](6) NOT NULL,
CONSTRAINT [PK_Student_1] PRIMARY KEY CLUSTERED
(
[studentNo] 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
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].[Score] CHECK CONSTRAINT [FK_Score_Course]
GO
IF NOT EXISTS (SELECT * FROM sys.foreign_keys WHERE object_id = OBJECT_ID(N'[dbo].[FK_Score_Student]') AND parent_object_id = OBJECT_ID(N'[dbo].[Score]'))
ALTER TABLE [dbo].[Score] WITH CHECK ADD CONSTRAINT [FK_Score_Student] FOREIGN KEY([studentNo])
REFERENCES [dbo].[Student] ([studentNo])
GO
ALTER TABLE [dbo].[Score] CHECK CONSTRAINT [FK_Score_Student]
GO
IF NOT EXISTS (SELECT * FROM sys.foreign_keys WHERE object_id = OBJECT_ID(N'[dbo].[FK_Score_Term]') AND parent_object_id = OBJECT_ID(N'[dbo].[Score]'))
ALTER TABLE [dbo].[Score] WITH CHECK ADD CONSTRAINT [FK_Score_Term] FOREIGN KEY([termNo])
REFERENCES [dbo].[Term] ([termNo])
GO
ALTER TABLE [dbo].[Score] CHECK CONSTRAINT [FK_Score_Term]
GO
IF NOT EXISTS (SELECT * FROM sys.foreign_keys WHERE object_id = OBJECT_ID(N'[dbo].[FK_Student_Class]') AND parent_object_id = OBJECT_ID(N'[dbo].[Student]'))
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。
