## 关于图书管理系统
建立一个图书馆管理系统,可以处理以下对象：
（1）图书馆基本信息
（2）图书馆的书籍
（3）图书馆管理员
（4）读者信息
### 需求分析
（1）查询图书馆的总信息
（2）查询图书馆藏书信息
（3）存入新书
（4）旧书处理
（5）根据书名检索书刊信息
（6）查询读者的借阅信息

## 概要设计
系统主要为开始界面和数据处理两大模块
开始界面即显示主要功能
数据处理包括：
查询图书馆的总信息
查询图书馆藏书信息
存入新书
旧书处理
根据书名检索书刊信息
查询读者的借阅信息
查询读者信息
读者借书
读者还书
文件保存
从文件读取
上述各模块通过主程序（main）进行调用，系统模块图如下:
