4.物理设计
4.1转换全局逻辑数据模型
4.1.1创建基本表
（给出创建每个基本表的SQL语句，应有如下实现：表名、列名、主键/侯选键、外键、参照完整性约束，对每个列，应有数据类型和长度、默认、是否可空等信息） (1)创建客户表 create table kehu(
khno varchar(20)not null primary key, khname varchar(20) not null, khtel varchar(20) not null, khsex varchar(10), khadd varchar(20) not null, check( khsex in('男','女')) )
数据插入
insert into kehu values(10001,'赵一',8800881,'男','上海号') insert into kehu values(10002,'钱二',8800882,'男','广州号') insert into kehu values(10003,'孙三',8800883,'女','北京号') insert into kehu values(10004,'李四',8800884,'男','厦门号') insert into kehu values(10005,'周五',8800885,'男','武汉号')

(3)创建收货人表
create table shouhuoren(
shrno varchar(20) not null primary key, shrname varchar(20) not null, shrsex varchar(10), shradd varchar(20) not null, shrtel varchar(20) not null, check(shrsex in ('男','女')), )
数据插入
insert into shouhuoren values(30001,'何一','男','上海号',88330001) insert into shouhuoren values(30002,'何二','男','上海号',88330002)
insert into shouhuoren values(30003,'何三','男','北京号',88330003) insert into shouhuoren values(30004,'何四','男','北京号',88330004) insert into shouhuoren values(30005,'何五','女','广州号',88330005) insert into shouhuoren values(30006,'何六','男','广州号',88330006) insert into shouhuoren values(30007,'何七','男','武汉号',88330007) insert into shouhuoren values(30008,'何八','女','武汉号',88330008) insert into shouhuoren values(30009,'何九','男','厦门号',88330009) insert into shouhuoren values(30010,'何十','男','厦门号',88330010)
(4)创建仓库表
create table cangku(
ckno varchar(20) not null primary key, ckadd varchar(20) not null, ckarea varchar(20) not null,
cktel varchar(20) not null, ckcap int not null ,
ckweight int not null default 0,
check(ckarea in ('上海','北京','广州','武汉','厦门')), )
数据插入
insert into cangku values(1,'上海号','上海',88118800,10000,0) insert into cangku values(2,'北京号','北京',88228800,10000,0) insert into cangku values(3,'广州号','广州',88338800,10000,0) insert into cangku values(4,'武汉号','武汉',88448800,10000,0) insert into cangku values(5,'厦门号','厦门',88558800,10000,0)
(5)创建运单表
