The thesis presents the design and development of an aviation information query system based on Spring Boot, JSP, and MySQL, aiming to improve the efficiency and accuracy of aviation data management. The system adopts a B/S architecture with a three-layer structure, supporting functions such as user login, flight information management, and airport data handling. It was developed using the Myeclipse platform and integrates technologies like Java and MySQL for backend data processing. A detailed feasibility and requirements analysis was conducted to ensure the system’s practicality, scalability, and security. Testing showed that the system performs well and meets the essential needs of aviation information handling. Although some interface and database optimizations are still needed, the system lays a solid foundation for modernizing airline information management.
