​
【实验内容及要求】

  1. 使用画图工具或MySQL Workbench等建模工具设计出相应的ER图，将局部ER图合并为一个整体ER模型，在ER模型中填加多样性约束，建立显示主键的ER模型，标识实体的属性，确认主键、外键。
  2. 将上述ER图转化为关系模式，要求标出每个关系的主码和外码
  3. 依据创建的模型，生成SQL语句，在MySQL里创建数据库和表

【实验平台】

Windows MySQL + MySQL Workbench

MySQL Workbench: MySQL
Workbench是为MySQL设计的ER/数据库建模工具。是著名的数据库设计工具DBDesigner4的继任者。具有设计和创建新的数据库图示，建立数据库文档，以及进行复杂的MySQL
迁移的作用

【实验步骤】

  1. 新建模型
    在这里插入图片描述

  2. 为表添加字段和完整性约束
    在这里插入图片描述

  3. 导出SQL语句
    在这里插入图片描述

  4. 执行SQL语句，产生数据库和表

【实验结果】

  1. ER模型
    在这里插入图片描述
  2. SQL文件
