ABSTRACT
With the growing amount of information managed by Information
Systems presented by different institutions, data integration poses
challenges, such as the execution of queries in multiple data sources
with computational cost and viable response time. The present work
describes a practical experiment, which had as main objective to
verify the performance of a OBDA tool with different DBMS in the
queries execution in SUS open data sources. The obtained results
indicate that the choice of the database management system can
influence the performance of the queries during the data integration
process. Discussing the performance of technological tools and
methods for integrating health data is a relevant topic to achieve
the objectives of access to information distributed in the different
Health Information Systems (HIS).
