基于ssm的共享客栈管理系统源码和论文-优快云博客

本文介绍基于SSM的共享客栈管理系统，开发工具为Idea，数据库采用MySQL 5.7+。系统在Eclipse环境中用Java语言编码，可实现房屋管理、合同文件上传下载等功能。该系统能集中管理信息，具有保密性强、效率高等优点，可降低信息管理成本。

基于ssm的共享客栈管理系统源码和论文058

开发工具：idea
数据库mysql5.7+
数据库链接工具：navcat,小海豚等
技术：ssm

摘要

互联网发展至今，无论是其理论还是技术都已经成熟，而且它广泛参与在社会中的方方面面。它让信息都可以通过网络传播，搭配信息管理工具可以很好地为人们提供服务。针对房屋出租信息管理混乱，出错率高，信息安全性差，劳动强度大，费时费力等问题，采用共享客栈管理系统可以有效管理，使信息管理能够更加科学和规范。

共享客栈管理系统在Eclipse环境中，使用Java语言进行编码，使用Mysql创建数据表保存本系统产生的数据。系统可以提供信息显示和相应服务，本系统实现房屋管理，合同文件上传与下载，房屋租房与续租，房屋出租管理等功能。

总之，共享客栈管理系统集中管理信息，有着保密性强，效率高，存储空间大，成本低等诸多优点。它可以降低信息管理成本，实现信息管理计算机化。
