一、项目简介
酒店推荐平台可以将功能划分为管理员功能和用户功能。
（1）管理员关键功能包含用户、客房类型、酒店客房、客房预定、入住登记、续订、退房、留言反馈、系统管理、个人资料等进行管理。
（2）用户关键功能包含客房预定、入住登记、续订、退房、个人资料等进行管理。（2）、用户关键功能包含客房预定、入住登记、续订、退房、个人资料等进行管理。
二、系统设计
2.1软件功能模块设计
本系统功能结构图：
2.2数据库设计
将“管理员、用户、酒店客房、留言反馈”等作为实体，它们的局部E-R图，如图4-2所示：
三、系统项目部分截图
3.1前台首页模块功能实现
系统首页页面如图5-1所示：
在注册流程中，用户在Vue前端填写必要信息（如用户名、密码等）并提交。前端将这些信息通过HTTP请求发送到Python后端。后端处理这些信息，检查用户名是否唯一，并将新用户数据存入MySQL数据库。完成后，后端向前端发送注册成功的确认，前端随后通知用户完成注册。这个过程实现了新用户的数据收集、验证和存储。如图5-2所示：
酒店客房：在酒店客房页面栏中输入酒店名称进行查询，可以查看到酒店客房详细信息，并根据需要进行在线预订或收藏等操作；如图5-3所示：
3.2后台模块功能实现
在登录流程中，用户首先在Vue前端界面输入用户名和密码。这些信息通过HTTP请求发送到Python后端。后端接收请求，通过与MySQL数据库交互验证用户凭证。如果认证成功，后端会返回给前端，允许用户访问系统。这个过程涵盖了从用户输入到系统验证和响应的全过程。如图5-5所示：
管理员功能实现
管理员进入主页面，主要功能包括对用户、客房类型、酒店客房、客房预定、入住登记、续订、退房、留言反馈、系统管理、个人资料等进行操作。如图5-6所示：
管理员点击酒店客房，在酒店客房页面输入客房名称进行搜索、新增或删除酒店客房列表，并根据需要对酒店客房详情信息进行查看、修改、查看评论或删除操作；如图5-8所示：
管理员点击客房预定，在客房预定页面输入酒店名称、套房类型、是否通过进行搜索、删除或审核客房类型列表，并根据需要对客房预定详情信息进行通过、查看、入住或删除操作；如图5-10所示：
3.3用户后台管理功能实现
用户进入主页面，主要功能包括对客房预定、入住登记、续订、退房、个人资料等进行操作。如图5-11所示：
