The Temporal Query Language TQuel

Summary: TQuel extends Quel with temporal constructs to query historical databases, enabling time-travel queries and temporal aggregation over enterprise histories. A minimal syntactic and semantic superset of Quel, TQuel adds compact temporal primitives to express HDB queries while preserving Quel's model. (summarized by gpt-5-mini on Feb 09 2026)
