Query Transformation for PSJ-queries

Summary: Query transformation for PSJ-queries: decide if a query can be computed from derived relations when both query and sources are PSJ-expressions. Contributions: PSJ-theory, reduced attribute mappings to prune search space, prototype PSJ-based transformation. (summarized by gpt-5-nano on Feb 09 2026)
