（一）项目简介与背景
民宿通常指的是自用住宅空闲房间，结合当地人文、自然景观、生态、环境资源等方面资源，以家庭副业方式经营，提供旅客居住生活的方式。近年来，民宿凭借其接地气、特色化、具有家庭氛围等优势，逐步发展成为一种住店潮流,深受国内外旅行者的喜爱。而民宿的管理水平的高低将直接影响到民宿的形象和声誉。伴随社会信息化脚步的发展，民宿服务只有走上网络化、智能化的发展之路，才能更好的满足人们对高标准、高质量和个性化服务的追求，因此，民宿管理系统的开发拥有着广泛的应用前景。
本项目旨在借助数据库相关知识打造符合实际需求，结构完整的民宿管理系统，采用Oracle数据库实现各项需求。分为房间管理、入住、餐饮、活动、评价、留言六大功能模块。
（二）项目功能
2.1房间管理
①房间信息录入：管理员可以向系统中录入房间的编号、房间号、房间类型、 房间价格（日租、短租、长租）、是否已入住的信息。
②房间信息查询：工作人员可以通过房间信息表查询房间的信息，需要精确， 模糊查询，如房间号查询，已入住房间查询，未入住房间查询，已入住客户信息查询等方式。
③房间信息管理：管理员可以根据需要，对房间的编号，房间号、房间类型、房间价格等信息进行添加，修改和删除等功能。
2.2入住管理
①预定功能：客户可以通过网络查询到各类的房间信息，包括基本图片、类型、价格、是否已经被预定、餐饮等信息。住客需要录入预定信息，预定信息包括住客的姓名、性别、身份证、联系方式基本信息和租赁方式、预定入住时间、预定退房时间。根据房间信息和人员信息判断能否预定成功。当系统接收到该房间被预定后，需将房间信息中是否预定的信息更变为已预定。
②入住办理：当客户办理入住手续时，如已预定，在登记住客身份证后将该用户预定信息一并记录。如未预定，在客户查询客房各类信息之后，登记其姓名、性别、身份证号、联系方式、入住房间、入住开始结束时间、租赁方式，房间已有入住人员则不允许办理入住。
③住客信息查询：工作人员可以通过住客登记的姓名、身份证，入住时间，房间号等查询到住客的住房信息以及其住房的历史记录等信息。
④退房办理： 在客户需要办理退房手续且上交房卡后，工作人员进行退房，先计算顾客总共消费，付钱后完成退房流程，在房间信息表中将该房间标记为未入住，同时更新入住记录和预定信息住客状态。
2.3餐饮
①餐饮信息录入：工作人员需向系统录入餐饮时间、价格、内容等信息。
②餐饮信息查询。
③餐饮信息修改。
④用餐人员信息录入：在接收到网上预定或入住办理时用户用餐的信息，工作人员需要将用餐人员的时间录入系统。
⑤用餐信息查询：工作人员，管理员可以通过日期，客户姓名，房间号、身份证号查询其用餐信息。
⑥用餐信息修改和删除。
2.4活动管理
①活动创建：工作人员可以定期组织租客举办交友，游戏等活动。此时工作人员需要将活动时间，内容，地点，收费等信息录入系统中。
②活动信息修改：工作人员可以修改活动信息。
③活动信息查询：管理员可以通过时间、名称查询活动信息，查询今后一周的活动信息。
④活动信息展示：客户可以通过民宿大屏幕查看活动信息。
⑤活动报名：在客户查询到未来的活动后，可以通过工作人员报名此活动，将自己的姓名、房间号或身份证等基本信息录入系统。
2.5评价模块
①评价：客户在办理退房手续后，可以对入住期间的环境，服务进行综合评价，打分。工作人员将评价信息录入系统。
②评价查询：客户、工作人员、管理员可以查询历史评价信息，包括好评，差评、综合查询方式。
2.6留言板块
①留言信息录入：租客可以通过工作人员留下自己在该地旅行居住的各类感受或者写简单的游记。
②留言信息展示：租客可以通过大屏幕赏阅历史的留言，游记等。

二、需求分析
系统开发之前，先要充分了解和熟悉有关民宿相关的信息，并区分其与一般旅馆的区别和其存在的特点，充分了解民宿管理系统中的所需功能项，从而使开发设计的系统可以全面便捷的概括所需的操作，以达到满足使用者的需求。
（一）业务流程图
一个简化的业务流程如图2所示：
图2 业务流程图
（二）数据流程
2.1数据流图
（1）顶层数据流图
一级数据流图包括主要的外部实体、数据存储对象以及流程，首先确定住客、前台人员、管理人员三个主要的外部实体，随后根据需求分析列出了入住预定与退房、餐饮信息管理、房间信息管理等六个流程。对于入住预定与退房以及活动管理还扩展了二级数据流图。最后的是存储表单的确定，根据系统信息需要我们共写出了客户信息、入住信息等十二个存储表。
（2）二级数据流图
二级数据流图是对一级部分流程的细化。入住预定与退房流程包含预定办理、入住办理以及退房办理三个业务流程；活动信息管理流程包括活动信息管理以及活动报名两个流程。
三、数据库概念模型
本民宿管理数据库设计主要实体对象包括客户、房间、活动、餐饮、评价、留言等，共12个实体模型。
图3 概念模型
四、数据库物理模型
（一）物理模型
物理模型是由概念模型通过PowerDesigner自动生成得到的，将概念模型中的联系转为外键引入到实体中，更能体现实体间的联系。
图4 物理模型
（二）数据库表
数据库的主要表格包括：
客户表
customer (customer_code, customer_name, gender, id, tel)
餐品表
dishes (food_code, food_name, food_price, food_content)
房间类型
room_type (room_type_code, room_type_name, room_day_price,
room_short_price, room_long_price, room_type_info, room_type_sums)
入住房间
room (room_code, room_name, check_out_confirm, room_type_code)
活动表 activity
(activity_code, activity_name, activity_type, activity_start_time, activity_end_time, activity_position, activity_content, activity_price)
报名表
activity_registration (customer_code, activity_code, activity_recode)
留言表 leave_message (message_code, customer_code, message_time, message_info)
评价表 customer_comment (comment_code, customer_code, comment_score,
comment_content)
订单表
customer_order (order_code, customer_code, order_time)
预定表
book (reservation_code, customer_code, room_type_code, order_code, lease_way, reservation_check_in_time, reservation_check_out_time, room_code_res)
入住表
check_in (check_in_code, room_code, order_code, check_in_lease_way, check_in_time, check_out_time, check_in_person_name, check_in_person_id_card, check_in_person_tel)
用餐表
dinning (dinning_code, food_code, check_in_code, dinning_time)
费用表 cost (cost_code, check_in_code, dinning_cost, room_cost, total_cost)
（三）表空间创建
表空间是Oracle数据库最大的逻辑单位，Oracle数据库通过表空间来组织数据库中的数据。一个数据库逻辑上由一个或多个表空间组成，一个表空间物理上是由一个或多个数据文件组成。在任何一个时刻，一个数据文件只能属于一个表空间，一个表空间只能属于一个数据库，反之则不成立。
永久表空间：专门针对用户的具体应用而创建的数据表空间，用户方案对象（如表、索引等）中的数据 就存放在此。
临时表空间：保存SQL语句在执行过程中所产生的临时数据（如查询操作中的记录排序、分组汇总等）。此类表空间通常不能存放用户数据，由系统自动管理，其中的数据不需要永久保存，属于“临时”性质。
本项目创建表空间如下：
3.1 永久表空间 HomeStay1_data
CREATE TABLESPACE HomeStay1_data DATAFILE 'D: \Data\local\sql\HomeStay1\HomeStay1_data. dbf'
SIZE 500M AUTOEXTEND ON NEXT 100M MAXSIZE UNLIMITED ONLINE;
3.2 临时表空间 HomeStay_temp
CREATE TEMPORARY TABLESPACE HomeStay1_temp TEMPFILE
'D:\Data\local\sql\HomeStay1\HomeStay1_temp.dbf' SIZE 500M AUTOEXTEND ON NEXT 100M MAXSIZE 500M;
（四）用户创建
Oracle数据库对安全性的管理，使用用户以及授权权限来达到安全性。下面是对住客、老板、前台分别创建的用户，并为其授予权限。创建授权如下：
4.1 创建管理员用户
CREATE USER manager1 IDENTIFIED BY 123 DEFAULT TABLESPACE HomeStay1_data QUOTA UNLIMITED ON HomeStay1_data TEMPORARY TABLESPACE HomeStay1_temp;
GRANT dba TO manager1;
4.2 创建前台用户
create user proscenium identified by proscenium123 TEMPORARY TABLESPACE HomeStay_temp;
GRANT CONNECT TO proscenium;
（五）关键应用编程实现
顾客注册账号、预定房间、顾客入住、顾客入住办理、顾客退房办理、费用结算、用餐、活动报名、在表中插入相关的新信息、留言和评价。下面展示用存储过程实现的一些主要功能。
5.1 预定功能
通过传入顾客编号、预定房间的类型编号、租聘方式、预计入住时间、预计退房时间，先进性判断各信息是否正确，房间是否有空缺，最后预定成功插入相关表中.
CREATE OR REPLACE PROCEDURE Customer_book(
c_code varchar2, rt_code varchar2, --顾客编号 房间类型编号
l_way varchar2,re_citime DATE, re_cotime DATE) -- 租聘方式 预定入住时间 预定退房时间
is
count1 number; --
r_code varchar(16);
r_name varchar(32);
begin
select count(*) into count1 from customer where customer_code = c_code;
if count1=0 then
dbms_output.put_line('该住客不存在！');
else
select count(*) into count1 from room where room_type_code = rt_code and check_out_confirm = 'n';
if count1=0 then
dbms_output.put_line('该房型预定已满不存在！');
else
INSERT INTO book(customer_code,room_type_code,lease_way,reservation_check_in_time,reservation_check_out_time)
values(c_code, rt_code,l_way,re_citime,re_cotime);
select room_code into r_code from (
select *from room where room_type_code = rt_code and check_out_confirm = 'n'
) where rownum <= 1;
update room set check_out_confirm = 'y' where room_code = r_code;
select room_name into r_name from room where room_code = r_code;
dbms_output.put_line('预定成功！,房间编号code为；'||r_code || '房间名：' || r_name);
end if;
end if;
end;
5.2 入住办理功能
通过传入房间编号、订单编号、租聘方式、入住时间、预计退房时间，进行入住办理。
CREATE OR REPLACE PROCEDURE do_checkin(
room_code varchar2, o_code varchar2, lease_way varchar, check_itime date, check_otime date,
check_name varchar2, check_id varchar2, check_tel number)
is
begin
INSERT INTO check_in(room_code,order_code,check_in_lease_way,check_in_time,
check_out_time,check_in_person_name,check_in_person_id_card,check_in_person_tel)
values(room_code, o_code, lease_way, check_itime,check_otime, check_name, check_id, check_tel);
end;
5.3 活动报名功能
通过传入顾客编号和活动编号先进性边界判断，最后报名成功，在相关表中添加报名信息。
create or replace procedure activity_registration_proc(
in_cus_code in customer.customer_code%type,
in_act_code in activity.activity_code%type) is
begin
declare
cus_name customer.customer_name%type;
act_name activity.activity_name%type;
cursor cur_cusName is select customer_name from customer where customer_code = in_cus_code;
cursor cur_actName is select activity_name from activity where activity_code = in_act_code;
begin
open cur_cusName;
open cur_actName;
fetch cur_cusName into cus_name;
fetch cur_actName into act_name;
if cur_cusName%found then
if cur_actName%found then
insert into activity_registration(customer_code, activity_code)
values(in_cus_code, in_act_code);
commit;
dbms_output.put_line(in_cus_code||'顾客：'||cus_name||'报名 '||in_act_code||' 活动 '||act_name||'成功！');
else dbms_output.put_line('未查到编号'||in_act_code||'活动！');
end if;
else dbms_output.put_line('未查到编号'||in_cus_code||'顾客！');
end if;
close cur_cusName;
close cur_actName;
end;
5.4 新建房间类型

else
insert into room_type(ROOM_TYPE_CODE,ROOM_TYPE_NAME,ROOM_DAY_PRICE,ROOM_SHORT_PRICE,ROOM_LONG_PRICE,ROOM_TYPE_INFO)
values (lxcode,lxname,dcost,scost,lcost,rinfo);
end if;
end;
5.5 费用结算功能

5.7 序列与触发器
触发器利用序列生成相关表的编号自增。下面是其中一个，其余10个触发器功能和这个类似，都是给表进行编号自增。
--序列与触发器
create sequence AUTOID1
increment by 1
start with 100001
nomaxvalue
nocycle
cache 10;
/*触发器用户编号生成*/
CREATE or replace TRIGGER MS_AutoID
BEFORE INSERT ON customer
FOR EACH ROW begin
SELECT ('ms'||trim(to_char(AUTOID1.NEXTVAL,'000000')))
INTO :NEW.CUSTOMER_CODE
FROM DUAL;
dbms_output.put_line('客户编号为'||:NEW.CUSTOMER_CODE);
End;

五、总结
本项目中，我的任务主要数据库模型的建立，概念模型图以及物理模型图，表结构和字段的具体设计，用触发器和存储过程实现活动报名功能和费用结算功能。在小组讨论好我们的所有表和联系后，我用PowerDesigner绘制了概念模型图，然后优化一下各个表的具体哪些字段、类型已经各表的主键、外键设计。概念模型需要确定系统中有哪些实体以及实体之间的联系，同时还要写上实体所有的属性名、主键等。联系不仅要写出联系名还要写出联系的类型，包括一对一、一对多等等。物理模型可以在概念模型的基础上自动生成，其会自动地将概念模型中的外键引入到实体属性中，同时箭头指向引入外键的实体。在设计费用结算时卡了很久，也不断进行优化数据和逻辑流程，因为涉及表比较多，也debug了很久，让我对于存储过程和多表之间的关联查询有了更加深刻的理解。
这个项目的背景是学校数据库实训课的大作业，给了五天的时间，要完成相关项目的数据库开发，因为时间问题所以并没有要求前后端，只需要有相关sql操作就行，触发器实现相关功能，纯粹是因为体现触发器的教学而使用的，实际上并不完全需要。
