一個簡單的三層架構之倉庫管理系統的入庫出庫

一個簡單的三層架構之倉庫管理系統的入庫出庫

今天來講一下一個簡單的三層架構的程序，一個倉庫管理系統的簡單的出庫入庫操作，還有供應商的信息錄入。
首先是在sql中（access也行）中建表，建表的字段設計如下

包括4個表（實際上我建的不止，後期擴展的有供應商的表格等等，很多需要後期加表），分別是，貨物屬性信息表、進貨入庫表，出貨出庫表，用戶信息表，以下詳細說明我的每個表，以下所有的表id均爲自動增加，不再說明
用戶表：一共三個字段，用戶名，用戶密碼，用戶權限

進貨表：入庫編號、貨物編號、貨物名稱、供應商名稱、倉庫名稱、貨物規格、計量單位、入庫數量、入庫價格、入庫總金額、入庫日期、經手人、備註

出貨表：出庫編號、倉庫名稱、貨物名稱、貨物規格、計量單位、出庫數量、出庫價格、出庫總金額、出庫日期、提貨單位、提貨人、經手人、備註

貨物信息表：貨物編號、貨物名稱、倉庫名稱、貨物規格、計量單位、貨物數量、貨物入庫價格、貨物出庫價格、貨物低線存儲、貨物頂線存儲、記錄修改人、修改日期

(供應商表不累加說明，自己按照之前的做就是了。很簡單。)

界面設計：(我一開始做的比較醜,簡單的功能先實現就好了）
主界面設計（多窗體（創建父窗體，子窗體等等））

供應商管理界面

入庫管理界面

出庫管理界面

類設計

好嘞，下面上代碼！（記住要創建app.config文件記住配置，配置過程網上有）
