只写个demo级的例程很好写，但用到生产环境中还得具体分析设计再编码。这种代码网上太多了内，你随便搜下就有了。
既然是商品库存系统，那么最少有各种商品的单件信息，1：需要有商品的进货价格，卖出价格，剩余数量，每月的销售数量，进货时间等，在对应的数据库表创建相应的字段。2：商品管理就是对多种商品的管理，所以还要有各种商品的分类，比如烟酒类，饮料类，小吃类，将其分类好管理，同样数据库里面建立相对的数据表。具体需要根据自己需求来编写。3:界面的设计，这里可分为登陆界面，其中一个是用户登陆后查看的界面，和管理员登陆后查看的界面，用户登录只能查看对应的商店的物品管理，并且能进行修改自家商品。管理员登陆可查看所有的用户的商店物品，及修改物品信息。而物品分类栏就可以用jQuery来实现局部的刷新界面。左边为物品分类栏，右边为选中物品类的信息。点击右边分类物品的某件物品，可跳转到该类物品的单个信息，如第1点提到的。
