Efficient Uncertainty Tracking for Complex Queries with Attribute-level Bounds

Summary: Introduces attribute-annotated uncertain databases (AU-DBs) that bound tuples and attribute values to compactly approximate incomplete data. Provides a scalable evaluation semantics closed under relational algebra with aggregation, using accuracy-for-performance optimizations for complex queries. (summarized by gpt-5-nano on Feb 09 2026)
