Effective data management is crucial to companies' competitiveness and operational efficiency. While big data has the potential to help small and medium-sized enterprises (SMEs) innovate their products, many companies find it challenging to utilize this digital capability effectively. Therefore, this article examines the nuances of data management in Portugal, highlighting visible differences between SMEs and large companies. With that purpose, data were collected from 390 Portuguese companies, and a Kruskal-Wallis Test was conducted to examine if significant differences exist in data exploitation between small and large companies. The main results indicate a noteworthy difference in the use of data for developing new services and the utilization of technologies for Data Storage Security, Security for Data Exchange with partners, and Cloud Computing Security between Small and Medium-Large Companies.engData managementAsset managementSMEsLarge Companiesconference paper2026-02-13cv-prod-4075628
