1、项目介绍

技术栈：
Python语言、Django框架、Highcharts可视化、MySQL数据库、HTML

随着当前科学技术的发展，人类对于知识的需求日益增大，图书馆就成为人类获取知识的重要场所，而开发一个图书管理系统对图书进行管理的需求随之增大。
本论文所研究的课题是以 Django为基础，设计并实现了一个以 Python为核心的图书管理系统，其中的程序采用了Django中的Web框架，而数据库则采用了 Django中的 SQlite。本系统在设计上简易、直观，方便用户进行使用，除了图书管理方面，还可以对书籍等信息进行数据可视化功能。
基于上述技术，本系统满足实际生活中的图书管理系统的功能需求。本系统主要实现了登录、主页、借书、借阅记录、书籍、书籍类别、出版者、会员、个人中心等功能，主要设计登录模块、菜单模块、借阅模块、图书管理模块、个人中心模块这几大模块。经测试，本系统运行状态良好，基本上满足开发需求。
文章的结尾部分，对全文所做的工作做了一个小结，并提出了今后的工作方向。
