Overview CSCI 1100 — Computer Science 1 Homework 8 Bears, Berries and Tourists Redux: Classes This homework is worth 100 points toward your overall homework grade, and is due Wednesday, December 11, 2019 at 11:59:59 pm. It has three parts. The first two are not worth many points, and may end up being worth 0.

实验二：用户自定义完整性约束及使用高级程序设计语言访问数据库 截止日期：2019 年 11 月 29 日 实验要求： 本次实验大约需要 3 小时。 严禁抄袭！若发现抄袭实验代码或虚构实验报告，本次实验成绩 为零分。 请认真完成所有实验内容，并于截止日期之前提交实验报告。实 验报告应简洁明了，请按照实验报告模板，最长不得超过 12 页。如 果你参考了他人的实验成果，请在实验报告中注明并致谢。 评分标准：按时提交（20%）+学术诚信（10%）+报告内容（70%）。 实验内容： 创建一个新的数据库，在该数据库下按要求创建如下表格，将所有SQL语句和要求的实验截图放在实验报告中。 职工（姓名，工号，年龄，年薪，所在部门编号）； 部门（部门名称，部门编号，部门负责人的工号）； 项目（项目名称，项目编号，主管部门编号）； 工作（职工工号，项目编号，工作时间）。 要求： • 表名和属性名用英文字符表示，表中各属性类型自行设计。创建表完成后加入样本数据（自行设计，4张表总计不少于16条数据）。[将插入样本数据后的各表截图保留在实验报告中] • 分析该关系模式中存在的各种数据约束，为这些表添加约束，包括主键、非空、外键等。在父表上update记录时，同步update子表上外键的值；当父表上记录被当做外键在子表中使用时，阻止对该记录的delete操作。 （请务必先插入样本数据，后设置约束，否则可能导致无法正常插入数据） • 执行违反数据约束的操作（自行设计，不少于5条），并观察结果；[将操作执行的结果截图保留在实验报告中] • 创建触发器，完成以下任务： • 当插入一项工作时，如果工作时间大于24，则将其设置为24。 • 当职工参加一个新的项目时，年薪增加5%；如果该职工是某部门的负责人，则再增加3%。 [将触发器的测试结果截图保留在实验报告中] • 创建一个用户worker，将“职工”表的查询权限以及“职工”表“年龄”列的修改权限赋予该用户。使用worker用户登录，并尝试修改“职工”表的“年龄”和“年薪”。完成后删除用户worker。 [将修改结果截图保留在实验报告中] • 学习使用高级程序设计语言（以Java为例）访问上述数据库，包括通过数据库连接API直接访问，和通过数据库连接池访问两种模式。 • 在高级程序设计语言中通过数据库连接API直接访问MySQL。 JDBC (Java Data Base Connectivity) 是一种用于执行SQL语句的Java API，可以 为多种关系数据库提供统一访问，它由一组用Java语言编写的类和接口组成。
