java专业课程设计小型图书标准管理系统.doc

资源描述

Java应用课程设计项目名称：小型图书管理系统课程名称：Java应用项目作者：* * * 完成日期：12月24日序言本系统是小型图书管理系统，专为个人设计。本系统开启后需要登陆，然后进入主界在这个界面我们能够选择所需要功效模块来完成所要实施功效。系统共有4个功效模块：图书入库、图书查询、图书删除、图书概览、修改密码。支持一系列相关图书管理方面简单操作,诸如查询、删除、添加、修改密码等。系统步骤图退出图书删除图书概览修改密码图书查询图书入库系统开始失败退出判定成功判定输入密码说明：首先是输入判定，相当于在登陆模块，要求用户输入用户名和密码；然后判定，假如判定失败退出系统，不然进入图书管理系统主界面。进入主界面后，用户要选择所需实施功效，即经过鼠标点击对应项，来完成所需操作。图书名图书号单价作者出版社入库时间表book 表user 用户名密码数据库表数据库设计在图书管理系统中，共设计2张表。本系统使用Access来创建数据表。数据库名称为Book.mdb。 1.表book 字段名称数据类型图书名文本图书号文本（主键）单价文本作者文本出版社文本入库时间文本 2.表user 字段名称数据类型用户名文本（主键）密码文本系统源码程序代码 1登陆界面:程序名Login.java import java.awt.event.*;
