- A platform for touristic visualisationPublication . Vasconcelos, João Miguel Mendes; Marques, Eduardo; Baras, KarolinaIn modern data analytics, visualisation platforms play a vital role in transforming raw data into useful insights. With the vast amount of data available online, these platforms make it easier to extract value by presenting complex information in clear, visual formats, enabling users to better understand the data and make well-informed decisions. Focusing on touristic data, the SmartDest project, developed by the University of Madeira, created a platform to collect, analyse, and visualise tourism-related data. However, a formal analysis of the existing platform identified several major issues: a limited diversity of graphs, a complete lack of dashboards, and significant performance issues in data visualisation that hindered effective analysis. To address these problems, the SmartDest platform architecture was systematically redesigned and implemented using a modern, open-source data stack comprising dbt Core for data trans formation, Apache Airflow for orchestration, and Apache Superset for visualisation. The project followed a multi-phase methodology, beginning with a heuristic review of the original platform, followed by the design and implementation of the new architecture. The solution’s effectiveness was then validated through four case studies targeting the identified problem areas. The evaluation confirmed that the new architecture resolves the identified limitations, providing flexible visualisations, performant data integration, and a solid governance framework. However, the results also highlight that these increased capabilities come with increased technical complexity and specific architectural trade-offs, including the lack of built-in Column-Level Security and constraints in multi-tenant embedded scenarios, which must be considered for future implementation.
