摘要

酒店推荐系统旨在提供一个全面酒店推荐在线平台，该系统允许用户浏览不同的客房类型，并根据个人偏好和需求推荐合适的酒店客房。用户可以便捷地进行客房预订，并在抵达后简化入住登记流程。为了确保连续的住宿体验，系统还提供续订功能，让用户无需重复预订过程。退房模块使得结账过程快速而高效。用户还可以通过留言反馈功能分享他们的住宿体验，帮助其他用户做出更明智的选择，并为酒店提供宝贵的客户意见。总的来说，这个系统旨在提升用户体验，同时帮助酒店更好地理解客户需求，并优化服务质量。

系统采用基于Python语言网站开发技术设计的，结合django框架和Mysql数据库管理系统对酒店推荐相关信息进行管理。按照软件工程学理论完成各阶段设计，经过调试测试达到了管理酒店推荐的能力。满足了管理员和用户的需要。论文从系统开发过程概述、开发工具简介、系统总体设计、系统开发、软件测试等几个方面进行了介绍。最后总结了系统开发的得失。

一、开发技术介绍

Python
Django
Vue
MySQL
协同过滤算法

二、功能介绍

根据需求说明设计系统各功能模块。采用模块化设计方法实现一个复杂结构进行简化，分成一个个小的容易解决的板块，然后再将小的板块继续分化成功能单一的更小模块。模块化设计方法使测试调试、维护更容易，减少模块间的干扰。各模块可以同时开发提高开发效率。本系统功能结构图：
