Design and implementation of a web application for SQL learning

This bachelor thesis focuses on the design and implementation of a gamified web application for learning SQL. The main objective was to design and develop a functional prototype of the first level that combines practical SQL query exercises with game elements and a narrative scenario, and to evaluate its benefits through user testing. The theoretical part is based on the analysis of gamification principles in education, a review of existing learning applications, and an analysis of syllabi of selected university courses focused on database systems. Based on these findings, a concept of the application was designed, incorporating a story-driven approach and interactive problem-solving using SQL queries. The application was implemented as a web-based system using React and Node.js technologies. The development followed an iterative approach with an emphasis on user experience. The thesis also includes user testing, which provided feedback on usability and the perceived benefits of the application. The results suggest that a gamified approach can positively influence student motivation and engagement in learning SQL. At the same time, the limitations of the solution are discussed and directions for future development are proposed.
