篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了库存物资管理系统相关的知识,希望对你有一定的参考价值。
1、背景资料:
1、有一个存放商品的仓库,每天都有商品出库和入库。
2、每种商品都有名称、生产厂家、型号、规格等。
3、出入库时必须填写出入库单据,单据包括商品名称、生产厂家、型号、
规格、数量、日期、时间、入库单位(或出库单位)名称、送货(或提货)人
姓名。
2.系统要求与功能设计
2.1 页面要求
(1)能够在 Tomcat 服务器中正确部署,并通过浏览器查看;(1 分)
(2)网站页面整体风格统一;
2.2 设计要求
1、设计出入库单据的录入。
2、实现按商品名称、出入库日期的查询。
一、商品的增删改查
dao层
与数据库连接有关的代码
