项目介绍

  小型超市商品管理系统是一款针对小型超市日常运营需求设计的软件解决方案。该系统主要内容有商品类别管理、商品库存管理、入库信息管理、销售订单管理等功能，实现了对超市商品的全面管理。它简化了商品管理流程，提高了工作效率，有助于超市管理者实时掌握商品动态，优化库存结构，降低运营成本。
本论文将总体分析小型超市商品需求，再从不同角度分析具体功能需求，运用net相关技术，采用MySQL数据库，讨论如何设计并实现一个小型超市商品管理系统。分析和设计主要从管理员、采购员和销售员三个角色上展开研究，介绍了各个功能模块的实现，并通过系统测试对小型超市商品管理系统进行调试，将各个功能的测试结果与期望设计进行逐一比对，找出BUG和欠缺之处，从而进一步优化改进系统。
本套基于Java的小型超市商品管理系统的设计与实现，希望能让用户通过互联网得到方便而快捷的系统管理体验，在此基础的同时提高工作效益。

技术介绍

开发软件：VS 2017 （版本2017以上即可，不能低于2017）
数据库：SqlServer2008r2（数据库版本无限制，都可以导入）
开发模式：mvc
浏览器：谷歌浏览器

功能介绍

本文从小型超市商品管理的实际需要出发，为降低系统的耦合性，完成了系统总体架构的设计，以提高系统的重用性、可适用性及可维护性。系统包括管理员、采购员和销售员三个角色；
管理员负责对整个系统进行管理和监控，而其他用户则负责执行具体的管理工作。管理员、采购员和销售员
系统整体模块分为管理员、采购员和销售员三大用户角色,整体功能设计图如下所示:
