SQL service 数据库某工厂的物料管理系统数据库设计与实现

喜欢ヅ旅行 2023-10-09 12:22 8阅读 0赞

1.  实现物料的分类管理；
2.  实现部门和员工信息管理；
3.  实现物料的入库和领用管理；
4.  实现物料的转仓管理；
5.  创建触发器，实现物料入库和领用时相应物料库存的自动更新；
6.  创建触发器，实现转仓时转入仓库物料增加、转出仓库物料减少；
7.  创建存储过程统计各仓库各种物料的现存数量；
8.  创建存储过程统计指定时间段内各种物料的入库数量和领用数量；
9.  建立数据库相关表之间的参照完整性约束；

逻辑结构设计

局部E-R图

实体： 部门：部门号,部门名

员工：员工号,姓名,性别,电话,职称

仓库：仓库号,仓库名

物料：物料编号,物料名称,类型

实体联系：

员工和部门：一个员工属于一个部门,一个部门可以有多个员工,属于多对一的关系；

![20190925172816250.png][]

员工和物料：物料由员工领用，一个员工可以领到多种物料,不同的物料也可以有不同的员工来领，它们属于多对多的关系；
