arXiv:2606.18621v1 Announce Type: new Abstract: Relational databases are widely used for managing structured data in real-world systems. Detecting anomalies from such relational data is crucial for identifying fraud, risks, and abnormal behaviors, yet remains under-explored. The key challenges lie in the intrinsic complexity of relational data: multi-table attributes are high-dimensional and heterogeneous, making sparse abnormal clues easy to overwhelm by normal or irrelevant information; and anomalies may further manifest as abnormal connection patterns across different foreign-key relations,
The proliferation of complex relational datasets across various industries, combined with advancements in AI/ML techniques, makes robust anomaly detection a critical and currently under-explored area.
Enhancing anomaly detection in relational databases directly impacts fraud prevention, risk management, and the identification of unusual behaviors crucial for maintaining systemic integrity and security.
This research introduces methodologies to more effectively identify anomalies within high-dimensional, heterogeneous relational data, including complex connection patterns, which has historically been a significant challenge for existing systems.
