一个简单的三层架构之仓库管理系统的入库出库
#一个简单的三层架构之仓库管理系统的入库出库
今天来讲一下一个简单的三层架构的程序，一个仓库管理系统的简单的出库入库操作，还有供应商的信息录入。
欢迎大家添加 仓库管理系统群（matlab、c#、java均可，有需求请联系我们）721623451
首先是在sql中（access也行）中建表，建表的字段设计如下
包括4个表（实际上我建的不止，后期扩展的有供应商的表格等等，很多需要后期加表），分别是，货物属性信息表、进货入库表，出货出库表，用户信息表，以下详细说明我的每个表，以下所有的表id均为自动增加，不再说明
用户表：一共三个字段，用户名，用户密码，用户权限
进货表：入库编号、货物编号、货物名称、供应商名称、仓库名称、货物规格、计量单位、入库数量、入库价格、入库总金额、入库日期、经手人、备注
出货表：出库编号、仓库名称、货物名称、货物规格、计量单位、出库数量、出库价格、出库总金额、出库日期、提货单位、提货人、经手人、备注
货物信息表：货物编号、货物名称、仓库名称、货物规格、计量单位、货物数量、货物入库价格、货物出库价格、货物低线存储、货物顶线存储、记录修改人、修改日期
(供应商表不累加说明，自己按照之前的做就是了。很简单。)
界面设计：(我一开始做的比较丑,简单的功能先实现就好了）
主界面设计（多窗体（创建父窗体，子窗体等等））
供应商管理界面
入库管理界面
出库管理界面
类设计
好嘞，下面上代码！（记住要创建app.config文件记住配置，配置过程网上有）
