基于微信小程序的房屋租赁管理系统的设计与实现
摘要
随着信息技术在管理上越来越深入而广泛的应用，管理信息系统的实施在技术上已逐步成熟。本文介绍了基于微信小程序的房屋租赁管理系统的开发全过程。通过分析基于微信小程序的房屋租赁管理系统管理的不足，创建了一个计算机管理基于微信小程序的房屋租赁管理系统的方案。文章介绍了基于微信小程序的房屋租赁管理系统的系统分析部分，包括可行性分析等，系统设计部分主要介绍了系统功能设计和数据库设计。
本基于微信小程序的房屋租赁管理系统后端有管理员和中介。管理员功能有，个人中心，用户管理，中介管理，房屋信息管理，房屋类型管理，租房订单管理，租房信息管理，租房账单管理，房源管理，系统管理等。中介功能有，个人中心，房屋信息管理，租房订单管理，租房信息管理等。用户功能有，查看房屋信息，修改个人信息，租房订单，租房信息，租房账单。因而具有一定的实用性。
本站后台采用Java的SSM框架进行后台管理开发，可以在浏览器上登录进行后台数据方面的管理，MySQL作为本地数据库，微信小程序用到了微信开发者工具，充分保证系统的稳定性。系统具有界面清晰、操作简单，功能齐全的特点，使得基于微信小程序的房屋租赁管理系统管理工作系统化、规范化。

Abstract
With the deepening and extensive application of information technology in management, the implementation of management information systems has gradually matured in technology. This article introduces the whole process of the development of the housing rental management system based on WeChat applet. By analyzing the deficiencies in the management of the housing rental management system based on the WeChat applet, a computer management solution for the housing rental management system based on the WeChat applet was created. The article introduces the system analysis part of the housing rental management system based on WeChat applet, including feasibility analysis, etc. The system design part mainly introduces the system function design and database design.
The back end of the housing rental management system based on WeChat applet has administrators and intermediaries. Administrator functions include personal center, user management, intermediary management, housing information management, housing type management, rental order management, rental information management, rental bill management, housing management, system management, etc. Intermediary functions include personal center, housing information management, rental order management, rental information management, etc. User functions include viewing housing information, modifying personal information, rental orders, rental information, and rental bills. So it has a certain practicability.
The background of this site uses the Java SSM framework for background management and development. You can log in on the browser for background data management. MySQL is used as a local database. WeChat applets use WeChat developer tools to fully ensure the stability of the system. The system has the characteristics of clear interface, simple operation and complete functions, which makes the management of the housing rental management system based on WeChat applet systematized and standardized.
Keywords: Housing rental management system based on WeChat applet; SSM framework; MYSQL database文章来源：https://www.toymoban.com/news/detail-816485.html
