Multiplatform system for hotel reservations: design, evaluation, and implementation

Introduction.It was identified that reservation management in the hotel sector depended on multiple devices and lacked a centralized system, which led to lost reservations, inconsistencies in availability, and a fragmented user experience. Given this scenario, the objective was to design and implement a multi-platform, web-centric, and responsive solution that would guarantee consistent access from any device and improve operational efficiency.Development.A three-layer architecture (presentation, business logic, and data) was modeled, and technological alternatives were evaluated using weighted criteria (time, process stages, efficiency, cost, and impact). The analysis determined PHP as the backend option due to its speed and cost-efficiency; HTML/CSS/JavaScript was integrated into the frontend to ensure accessibility and maintainability; and MySQL was selected for the data layer due to its robustness and scalability. XAMPP was used to speed up iterations and local testing. The solution was developed with a responsive interface, cross-browser compatibility, real-time availability updates, and operation traceability, incorporating basic security controls and good design practices.Conclusion.The implementation of the unified system allowed reservations to be made from any device with a browser, reduced friction and abandonment, increased the conversion rate, and mitigated overselling errors. Staff managed inventory and reservations with greater agility, having consistent data available for decision-making. As future work, it was recommended to integrate PMS and channel manager via API to synchronize OTAs, strengthen security, and establish performance and accessibility metrics (WCAG), consolidating a scalable technological base to maintain competitive advantages.
