数据库设计部分：
```go
```c
create database chat
use chat
if exists (select * from sys.sysobjects where name='register')
drop table register
go
create table register
(
Rid int primary key identity,
RcreateTime nvarchar(50) ,
Rusername nvarchar(20) ,
Rpassword nvarchar(20) ,
Remail nvarchar(30) unique
)
select * from register
if exists (select * from sys.sysobjects where name='PersonalInformation')
drop table PersonalInformation
go
create table PersonalInformation
(

Pstate int default 0 ,-- 1代表在线，2代表隐身，0代表离线。
