图书管理系统是一个用于图书馆或书店管理图书信息、借阅记录和读者信息的应用程序。本系统使用Java Swing框架进行开发,提供直观的用户界面,方便图书馆管理员或书店工作人员对图书信息进行管理。以下是系统的设计、功能和实现的详细报告。
技术选型:
前端框架: Java Swing
后端语言: Java
数据库: 使用文件存储图书信息
系统架构:
MVC(Model-View-Controller)架构,以确保系统的可维护性和扩展性。
Model: 数据模型,包括图书、读者和借阅记录等类。
View: 用户界面,使用Swing组件实现各种窗口和表格。
Controller: 控制器,处理用户输入、调用业务逻辑和更新视图。
图书管理:
添加图书信息,包括书名、作者、出版社、出版日期等。
修改图书信息,支持编辑已有图书的属性。
删除图书,从系统中移除不需要的图书。
查询图书,根据书名、作者等条件进行搜索。
读者管理:
添加读者信息,包括姓名、学号(或工号)、联系方式等。
修改读者信息,更新读者的个人信息。
删除读者,从系统中注销读者账号。
查询读者,根据姓名、学号等条件进行搜索。
借阅管理:
借书,记录图书的借阅信息,包括借阅日期和应还日期。
还书,更新图书的借阅状态,计算逾期天数和罚金。
查询借阅记录,查看读者的借阅历史。
登录界面: 提供用户名和密码登录系统。
主界面: 显示图书管理、读者管理和借阅管理等功能按钮。
图书管理界面: 包括添加、修改、删除和查询图书的功能。
读者管理界面: 包括添加、修改、删除和查询读者的功能。
借阅管理界面: 包括借书、还书和查询借阅记录的功能。
