超市进销存管理系统(C#+SQL Server实现)窗体应用、数据库应用,设计模式
设计环境及开发工具:
需求分析
系统设计
数据流图及程序结构框图
数据库概念结构设计
数据库逻辑结构设计
数据库物理结构设计
系统实现(C#语言)
最后生成可执行的安装包程序
期末大作业纷涌而来,长时间没有更新博客,更新一个SQL server的大作业,使用C#实现超市进销存管理系统,对数据库进行概念设计、逻辑设计、物理设计以及实现,确定需求目标,画出程序结构图,写出数据字典以及数据流程图,分析各实体集的属性及其之间的关系,系统实现。
超市管理系统是一个典型的进销存管理系统,其旨在解决超市商品的采购、销售、仓储等一系列操作流程中的数据信息的处理问题,提供一系列的数据分析 ,帮助经营者合理的调整各个经营运作环节的运作节奏,并对商品流转过程进行了全程跟踪管理、相应款项流通的全程记录管理和票据信息统计的管理。因此超市进销存管理系统的全面应用,规范业务流程、提高了超市的管理水平,提高资金流动的透明度,加快商品资金周转速度,进而全面提高了超市的经营水平、进而全面提升了超市的经济效益。
超市管理系统采用. NET技术和大型数据库SQL Server 2016 开发,主要是处理超市商品的采购、库存和销售各个环节的活动,具有良好的人机界面;考虑到系统的使用对象可能较多,权限管理良好;数据查询方便,支持多条件查询;系统支持良好的数据备份和还原操作,有效保护数据,减少意外损失;在相应的权限下,可方便地删除数据;数据计算自动完成,尽量减少人工干预。
操作系统: Windows 10。
数据库管理系统:选用Mircrosoft 公司的Sql Server 2016数据库管理系统。
开发工具:选用visual studio 2019
超市管理是多数大型超市日常经营管理中十分重要的一个组成部分,传统的手工管理方式呈现出越来越多的弊端。在手工管理模式下,统计,汇总处理时的工作量极其繁重,处理效率非常低,领导也无法及时了解超市资金占用的实际状况。通过系统管理,企业可以直观分析超市的情况,提高超市的竞争能力。
通过资料与实际调查,要求本系统具有以下功能。
1.具有良好的人机界面。
2.如果系统的使用对象较多, 则要求有良好的权限管理。
3.方便的数据查询,支持多条件查询。
4.系统支持良好的数据备份和还原操作,有效保护数据,减少意外损失。
5.在相应的权限下,可方便地删除数据。
6.数据计算自动完成, 尽量减少人工干预。
7.销售情况打印功能。
8.动态查询
超市管理系统主要由基本信息管理、进货管理、销售管理、库存管理、系统维护等模块组成,具体规划如下:
基本信息管理模块。基本信息管理模块主要用于实现系统基本数据的录入。
进货管理模块。 该模块主要用于实现商品的进货数据录入、退货数据录入和进货查询分析。
销售管理模块。该模块主要用于实现商品的销售数据录入、客户退货数据录入和销售信息查询。
库存管理模块。库存管理模块主要用于实现库存调拨、库存商品数量上限报警和库存数据查询。
系统维护模块。系统维护模块用于实现系统用户设置、操作权限设置、密码修改、数据备份和数据恢复。
本系统后台数据库中的数据表有:
tb_Company(公司基本信息表)
tb_Customer(会员基本信息表)
tb_Department(部门基本信息表)
tb_Depot(仓库类别信息表)
tb_Goods(商品进货信息表)
tb_Popedom(系统权限信息表)
tb_Post(员工职位表)
tb_ReGoods(商品退货信息表)
tb_Sell(商品销售信息表)
tb_Stock(库存信息表)
tb_StockTemp(库存调拨信息表)
tb_Unit(商品信息表)
tb_User(员工基本信息表)
实体集:
商品信息实体、员工信息实体、退货商品实体、商品销售实体、商品库存实体,商品调拨信息实体
实体属性:
商品信息实体:商品进货ID,进货员工ID,进货公司,仓库类别,商品名称,进货数量,进货时间,进货价格,销售价格
员工信息实体:员工姓名,员工性别,系统登陆名,系统登陆密码,所在部门,员工职位,
家庭住址,家庭电话,联系电话
退货商品实体:退货商品ID,商品名称,客户ID,公司名称,仓库名称,退货时间,退货数量,退货原因
商品销售实体:销售ID,商品ID,销售数量,商品规格,销售价格,应付金额,实付金额
商品库存实体:库存ID,商品ID,库存名称,商品名称,库存数量,报警数量,应付金额,实付金额
商品调拨信息实体:调拨ID,操作员ID,商品ID,商品名称,调出仓库,调入仓库,调动数量
部分表如下:
