An INESC TEC research on data replication in relational databases received an honourable mention at SIGMOD 2025, one of the leading international conferences in the field of data management – ranking among the four best papers out of 250 submissions.
The paper CRDV: Conflict-free Replicated Data Views presents a new model for conflict-free data replication adapted to the relational paradigm, such as SQL, in which data are organised into tables with rows and columns – currently the most widely used structure.
The proposed solution allows direct reading and writing on copies of these databases, while providing customisable data structures and conflict resolution rules, making the process more efficient and flexible.
The efficiency is further improved by optimisation features in the query engine, including support for secondary indexes and advanced control over data materialisation.
“With distributed databases becoming increasingly common, this solution introduces advantages to the state of the art, as it ensures consistency, performance and flexibility in handling replicated data,” said Nuno Faria, INESC TEC researcher in distributed systems.
Co-authored with José Orlando Pereira, also a researcher at INESC TEC, this recognition adds to the recent track record of excellence by INESC TEC teams working in the field of distributed systems, with regular publications in top-tier data management conferences, including SIGMOD, VLDB and others.
The researchers mentioned in this news piece are associated with INESC TEC and U.Minho.
