一·、毕设设计题目
图书管理系统
二、毕设设计目的
通过对图书管理系统的系统分析、系统设计、编码和调试等工作的实践，熟悉管理信息系统的开发过程、设计方法及编程技术，熟悉掌握数据库设计的基本理论及方法。
三、需求概述
图书管理系统的基本功能需求包括：读者管理、图书管理、借阅管理、用户登录与用户管理等；其它功能需求包括：读者查询与预约借书*、统计与报表*、数据备份*、书架管理*、期刊管理*、期刊借阅*、论文管理*、论文借阅等。（ 表示留待以后的迭代周期完成，下同）
四、设计准备
系统准备
操作系统：Windows 10
数据库系统：mysql
客户端开发工具：IDEA，Navicat
知识准备
熟悉mysql的使用；
熟悉Java语言及其数据库编程技术。
了解：迭代式开发过程、UML设计文档、设计模式；以及图书馆相关业务知识。
迭代式开发
迭代式开发（统一过程UP） 系统开发被组织成一系列固定的短期（一段为2-6周）小项目，称为迭代；每次迭代都产生可执行的系统。每次迭代都包括计划、需求、分析、设计、编码、测试等过程以及文档编写工作；本文转载自http://www.biyezuopin.vip/onews.asp?id=14704第一次迭代考虑系统的核心功能，随后的迭代逐步扩展系统功能；每次迭代的成果（含需求、分析、设计、代码和文档等）均为下一次迭代的工作基础，直至满足最终需求。这种开发过程是基于面向对象方法的。
技术栈
前端： Thymeleaf、Layui、Ajax、JQuery
后端 ： springboot , mybatis
开发环境： IDEA 、SpringBoot 2.3、Maven
数据库：MySQL 5.7
