</html>接下来是数据库的sql：
use master
go
create database EstateDB
go
use EstateDB
go
create table T_building(
Id varchar(20) primary key not null,
Company varchar(40) not null,
Phone varchar(20) not null,
Description varchar(200) not null,
Status varchar(8)
)
insert into T_building(Id,Company,Phone,Description,Status)
values ('001','恒大地产','0731-88859908','东湖花园，10.1开盘','审核通过')
insert into T_building(Id,Company,Phone,Description,Status)
values('002','旭日地产','0731-82285588','戏子花园，10.1开盘','未审核')
insert into T_building(Id,Company,Phone,Description,Status)
values('003','万达地产','0731-84155688','万哒花园，10.1开盘','未审核')
go调试下，就可以运行啦。
还有主页面的code：

会在操作二中附源码和后台java code。
