RESEARCH OF THE SOFTWARE REENGINEERING MODELS EFFECTIVENESS FOR THE TOURISM SERVICES DIGITAL TRANSFORMATION

Abstract

The paper investigates the effectiveness of software reengineering models as a key tool for the digital transformation of tourism information systems. The object of the study is the software of a tourism platform, while the subject is the processes of optimizing its architecture, performance, security, and quality of user service. Special attention is given to in-depth analysis of source code, reverse engineering, architecture redesign, and the implementation of multi-layered models using modern technologies such as PHP, MySQL, OAuth, and password hashing. The practical part is based on the reengineering of the Travel-website web application, which includes detailed code analysis, development of an updated architecture, integration with Google OAuth, enhancement of password storage security, and implementation of an adaptive interface to improve user experience.The paper substantiates the necessity of adapting software systems to the requirements of digital transformation, which is especially relevant under conditions of intense competition and martial law. The research results indicate that reengineering significantly improves system security, flexibility, and performance, which is critically important for modern tourism services. The introduction of multi-factor authentication, as well as integration with CRM and analytical systems, expands the platform’s functional capabilities, ensuring its competitiveness in the market. The proposed reengineering model is an effective tool for digital transformation, enabling the improvement of quality and reliability of tourism information systems. Furthermore, the article addresses the optimization of development costs and time through the use of proven reengineering strategies and technologies, making the proposed approach economically advantageous and practically applicable in the current IT industry environment.
