1、项目介绍及开发技术

1.1 项目介绍

近年来，信息化管理行业的不断兴起，使得人们的日常生活越来越离不开计算机和互联网技术。首先，根据收集到的用户需求分析，对设计系统有一个初步的认识与了解，确定供应商管理系统的总体功能模块。然后，详细设计系统的主要功能模块，通过数据库设计过程将相关的数据信息存储到数据库中，再通过使用关键的开发工具，如IDEA开发平台、AJAX技术等，编码设计相关的功能模块。接着，主要采用功能测试的方式对系统进行测试，找出系统在运行过程中存在的问题，以及解决问题的方法，不断地改进和完善系统的设计。最后，总结本文介绍的系统的设计和实现过程，并且针对于系统的开发提出未来的展望工作。本系统的研发具有重大的意义，在安全性方面，用户使用浏览器访问网站时，采用注册和密码等相关的保护措施，提高系统的可靠性，维护用户的个人信息和财产的安全。在方便性方面，促进了供应商管理系统的信息化建设，极大的方便了相关的工作人员对供应商管理系统信息进行管理。

1.2 开发技术

Java开发语言、SpringBoot、MyBatisPlus、MySQL数据库、Maven、IDEA开发工具、JDK1.8+、Vue、HTML、CSS、JS。

管理员可以选择任一浏览器打开网址，输入信息无误后，以管理员的身份行使相关的管理权限。

?商品管理：管理员可以通过选择商品管理，管理相关的商品信息记录，比如进行查看商品信息标题，修改商品信息来源等操作。

公告管理：?管理员可以通过选择公告管理，管理相关的公告信息记录，比如进行查看公告详情,删除错误的公告信息,发布公告等操作。

?公告类型管理：管理员可以通过选择公告类型管理，管理相关的公告类型信息，比如查看所有公告类型,删除无用公告类型,修改公告类型,添加公告类型等操作。

供应商管理:?新增供应商,修改供应商,删除供应商。

供应商类型管理：?新增供应商类型,修改供应商类型,删除供应商类型。

4、数据库表结构设计
