View Matching for Outer-Join Views

Summary: First view-matching algorithm for SPOJG views (outer joins included) using join-disjunctive normal form. No bottom-up matching; handles inner/outer-join mixes with bag semantics, leveraging not-null, uniqueness, and foreign-key constraints. (summarized by gpt-5-nano on Feb 09 2026)
