In order to improve the efficiency of hotel management business, a multi-terminal and controllable hotel management system has been designed and implemented in a targeted manner. The system can meet the current and future requirements for efficient collection, storage, processing, organization, management, and utilization of information resources, achieving a more efficient and convenient management model. The PC front-end uses Vue and Element frameworks, the mobile front-end uses Uniapp framework combined with WeChat mini program technology, and the back-end uses Spring Boot framework and integrates multiple open-source technologies. The system has been applied to multiple chain hotels, running stably and reliably, and has strong practical value.
