The Tree Property Is Fundamental For Query Processing (Extended Abstract)

Summary: Partition schemas into tree vs cyclic; prove that computing full-join projections using join/project/semijoin is equivalent to constructing an embedded tree schema (a tree projection). Use tree projections to characterize solvability and bound the number of joins required. (summarized by gpt-5-mini on Feb 09 2026)
