数据库设计
1、要求
（1）绘制所建数据库的E-R模型图
（2）表（实体表和关联表）结构的设计
（3）录入数据的表（每个表5条记录即可）
（4）说明组内分工
2、设计内容
所设计数据库是订餐系统数据库。
- List 1
此次试验设计的是一款点餐系统，系统主要分为 Admin 和 User 两大部分。
Admin 部分主要可以进行查看订单、对点餐系统的维护管理、添加套餐组合与修改管理员信息操作。
User 部分进行的是用户的操作，新用户可以通过系统注册用户个人信息，注册成功的用户可以通过点餐系统进行用户信息的修改、点餐、个人订单信息的查询操作。
- List 2
这套系统是为了方便餐厅管理和用户点餐而设计的。我们通过使用 Mysql 设计了系统所需的表，
运用 Navicat 从 Mysql 数据库中调用相关数据，通过 JDBC 连接。
运用 myeclipse 中的 JAVA 可视化界面开发插件 Matisse 开发 UI 界面。
- List 3
Java 点餐系统中一共四个包：dbconnection、dao、model 和 view。
作用分别为连接数据库；对数据库中的数据进行处理；获取数据库数据以及给用户展示界面并提示用户进行相应的操作。
在进行实际应用操作情景中，根据用户输入的登陆信息，系统会判断使用者是管理员还是普通用户(管理员的信息中 id 系统后台默认的以分辨，登陆界面中注册时没有权限注册管理员，全部为用户id)，view 中的类将根据用户的触发项进行相应的页面转跳操作，view 中不同的类会根据用户的操作同
时调用其对应 dao 和 model 包中的类进行操作。
（1）E-R模型
goods表：
Id，goodsName，price，goodsDesc，imageLink
user表：
Id，userName，password，email，rank
order_info表：
orderId，orderStatus，orderNum，orderTotalMoney，userName
order_goods表：
Id，orderld，goodsTotalPrice，goodsId，goodsPrice，goodsNum，goodsName
（2）所有表的设计视图
goods表包含id，goodsName，price，goodsDesc，imageLink
其中id为主键。
CREATE TABLE `goods` (
`id` int(10) NOT NULL AUTO_INCREMENT,
`goodsName` varchar(100) DEFAULT NULL,
`price` float DEFAULT NULL,
`goodsDesc` varchar(200) DEFAULT NULL,
`imageLink` varchar(500) DEFAULT NULL,
PRIMARY KEY (`id`)）；
insert into `goods`(`id`,`goodsName`,`price`,`goodsDesc`,`imageLink`)
values (3,'宫保鸡丁',21,'宫保鸡丁哦','E:\java\eclipse\'),
(5,'青椒肉丝',22,'青椒肉丝不好吃','E:\java\eclipse\'),
(8,'麻婆豆腐',2,'香辣丝滑','E:\java\eclipse\’),
(9,'鱼香肉丝',9,'四川风味','E:\java\eclipse\'),
(10,'回锅肉',12,NULL,NULL),
(11,'热狗肠',32,'说的','E:\java\eclipse\');
user表包含id，userName，password，email，rank
其中id为主键。
CREATE TABLE `user` (
`id` int(10) NOT NULL AUTO_INCREMENT,
`userName` varchar(100) DEFAULT NULL,
`password` varchar(50) DEFAULT NULL,
`email` varchar(200) DEFAULT NULL,
`rank` int(1) DEFAULT '0',
PRIMARY KEY (`id`));
insert into `user`(`id`,`userName`,`password`,`email`,`rank`)
values
(1,'admin','123',NULL,1),
(8,'aaa','123','[email protected]',0),
(9,'admin1','123',NULL,0);
order_info表包含orderId，orderStatus，orderNum，orderTotalMoney，userName
其主键为orderId。
CREATE TABLE `order_info` (
`orderId` varchar(50) NOT NULL,`orderStatus` int(10) DEFAULT NULL,
`orderNum` int(10) DEFAULT NULL,`orderTotalMoney` float DEFAULT NULL,
`userName` varchar(100) DEFAULT NULL,PRIMARY KEY (`orderId`));
insert into
`order_info`(`orderId`,`orderStatus`,`orderNum`,`orderTotalMoney`,`userName`)
values ('20130708001514',3,1,12,'admin1'),
('20130708021437',1,1,12,'admin1'),('20130708110510',2,2,31,'aaa'),
('20130708110513',3,2,44,'aaa'),('20130708115503',1,1,2,'admin1'),
('20130708115508',4,2,44,'admin1'),('20130708115512',3,1,22,'admin1'),
('20130708121456',4,1,9,'admin1');
order_goods表包含id，orderld，goodsTotalPrice，goodsId，goodsPrice，goodsNum，goodsName
其中主键为id。
CREATE TABLE `order_goods` (
`id` int(10) NOT NULL AUTO_INCREMENT,
`orderId` varchar(50) DEFAULT NULL,
`goodsTotalPrice` float DEFAULT NULL,
`goodsId` int(10) DEFAULT NULL,
`goodsPrice` float DEFAULT NULL,
`goodsNum` int(10) DEFAULT NULL,
`goodsName` varchar(100) DEFAULT NULL,
PRIMARY KEY (`id`),
KEY `FK_order_goods_2` (`orderId`),
KEY `FK_order_goods_1` (`goodsId`),
CONSTRAINT `FK_order_goods_1` FOREIGN KEY
(`goodsId`) REFERENCES `goods` (`id`),
CONSTRAINT `FK_order_goods_2` FOREIGN KEY
(`orderId`) REFERENCES `order_info` (`orderId`)
);
Insert into
`order_goods`(`id`,`orderId`,`goodsTotalPrice`,`goodsId`,`goodsPrice`,`goodsNum`,`goodsName`)
values (23,'20130708001514',12,10,12,1,'回锅肉'),
(28,'20130708021437',12,10,12,1,'回锅肉'),
(31,'20130708110510',22,5,22,1,'青椒肉丝'),
