这是我参与 8 月更文挑战的第 23天，活动详情查看： 8月更文挑战
前言：
项目是使用Java swing开发，可实现基础数据维护、图书类型管理和维护、图书信息管理和维护、注销退出、关于作者简介等功能。界面设计比较简介、适合作为Java课设设计以及学习技术使用。
引言
随着计算机及网络技术的飞速发展，Intranet 应用在全球范围内日益普及， 当今社会正快速向信息化社会前进，信息系统的作用也越来越大。图书馆在正常运营中总是面对大量的读者信息，书籍信息以及由两者相互作用产生的借书信息，还书信息。因此图书管理信息化是发展的必然趋势。用结构化系统分析与设计的方法，建立一套有效的图书信息管理系统，可以减轻工作，将工作科学化、规范化，提高了图书馆信息管理的工作质量因此根据图书馆目前实际的管理情况开发一套冬书管理系统是一分必要的。
主要技术和工具：
eclipse+JDK1..8+Navicat +swing +mysql
功能截图：
图书类型管理：
图书类型管理维护、可以根据图书类型查看图书信息、可以根据编号和信息删除修改图书类型信息
图书信息管理：
图书信息维护管理、点击图书维护可以根据图书名称、作者以及图书类型模糊查询图书信息、可以点击下面的输入框进行数据修改和删除操作
选中数据进行修改和删除操作
图书添加：
作者简介：
注销退出：
