数据库设计：

/*商品信息表*/

/*id：序号 */

/*pdm：代码*/

/*pname：商品名字*/

/*povider：品牌*/

/*info：商品信息*/

/*stock：数量*/

/*price：单价*/

CREATE TABLE pro_T (

id int IDENTITY (1, 1) NOT NULL ,

pdm varchar (50) NOT NULL ,

pname varchar (50) NULL ,

provider varchar (50) NULL ,

info varchar (50) NULL ,

stock int NULL ,

price float NULL

) ON PRIMARY

/*用户表*/

/*username：用户名*/

/*password：密码*/

CREATE TABLE user_T (

username varchar (10) NOT NULL ,

password varchar (16) NOT NULL

) ON PRIMARY
