Optimization of Multiple-Relation Multiple-Disjunct Queries
Summary: Merge disjuncts into terms evaluated with one scan per relation to avoid redundant joins/scans in multi-relation, multiple-disjunct queries (no indices assumed). Model scan-minimization as covering a merge graph by minimum complete-merge graphs (NP‑complete); provide polytime algorithms for special classes and a heuristic for the general case.
