Variable Independence and Aggregation Closure
Summary: Introduce variable independence, a schema restriction (generalizing classical relational assumptions) that ensures closure of constraint-database languages under aggregation. Show for linear constraint databases that area and higher-dimensional aggregates fit this closed relational-algebra fragment. (summarized by gpt-5-mini on Feb 09 2026)
