KathDB: Explainable Multimodal Database Management System with Human-AI Collaboration
Guorui Xiao, Enhao Zhang, Nicole Sullivan, Will Hansen, Magdalena Balazinska
CIDR, 2026 | 2025 - Present
KathDB is an explainable multimodal DBMS that combines relational query optimization with
foundation model reasoning, enabling natural language queries over text, images, and video
while preserving structured semantics. My work focuses on the human-AI interaction layer,
exploring how users query, debug, and interpret multimodal results, and how the system can
best surface explanations and lineage to support understanding and trust.
