图书管理系统实验报告+源代码

图书信息管理系统课程设计：图书信息管理系统设计人员：林俊柱开发环境: eclipse数据库: sql server 2005说明：数据库里面的用户名为”sa”, 密码为：”1111”登录程序所用的用户名为: ljz ,密码为： 0000,当然，也可以使用注册功能，注册完成后使用自己的用户名和密码登录设计思路:该图书信息管理系统主要便于图书管理员管理教师的书籍借阅情况。

该程序实现的功能总共有五个板块：1、教师信息管理:包含了增加、删除、修改、查询教师信息等功能；2、图书信息管理:包含了增加、删除、修改、查询图书信息等功能；3、借书登记:登记教师借阅图书的相关信息；4、还书登记:登记教师归还图书的相关信息；5、催还:查询出并列出教师借阅图书超过期限的相关信息，以便催促教师还书.数据库的设计思路为：Teacher（读者号，姓名，性别，年龄，部门，联系方式）Book（ISBN，书名，作者，出版社，价格，类型）Borrow（读者号，ISBN，借阅日期，归还日期，办理人，归还办理人）（横线为主键，蓝色字体为外键）管理员信息表：Administrator（管理员编号，管理员密码，管理员姓名，性别，年龄，联系电话）数据库的连接：public class Dataclass {private static Connection conn = null;String driverName= "com.microsoft.sqlserver.jdbc.SQLServerDriver";String dbURL = "jdbc:sqlserver://localhost:1433;DatabaseName=Java 课程设计数据库 ";String userName="sa"; //默认用户名String userPwd="1111"; //密码//构造函数public Dataclass(){ //用于连接数库try {if (conn == null) {Class.forName(driverName);conn= DriverManager.getConnection(dbURL, userName,

null;}}public static boolean executeUpdate(String sql) { //发送不返回结果集的SQL语句try {if(conn==null)new Dataclass(); //调用构造函数连接数据库int i = conn.createStatement().executeUpdate(sql);if(i != 0)return true;}catch
