arXiv:2606.08491v1 Announce Type: new Abstract: Relational deep learning (RDL) converts relational databases (RDBs) into heterogeneous graphs, but graphs derived directly from database schemas are often not well suited for how graph neural networks (GNNs) perform relational reasoning. We study what makes a relational graph suitable for deep learning and show that schema-derived graphs suffer from two systematic failures: information overload and semantic fragmentation. Our empirical analysis reveals that the desired graph is not the raw schema, but a result of controlled structural adaptation.
The rapid advancement and adoption of deep learning models, particularly GNNs, mean optimizing their underlying relational data structures is becoming a critical bottleneck, prompting research into more effective data representations.
This research addresses a fundamental limitation in applying deep learning to relational databases, potentially unlocking significant performance gains and broader applicability for AI systems that rely on structured data.
The understanding of how relational databases should be structured and adapted for optimal performance in relational deep learning, moving beyond raw schema conversion to controlled structural adaptation.
