QC-Trees: An Efficient Summary Structure for Semantic OLAP

Summary: QC-Trees proposes a compact, direct representation for semantic OLAP summaries, replacing the quotient cube with the QC-tree. It provides algorithms for construction, query answering, and incremental maintenance, and demonstrates space/time gains over prior approaches. (summarized by gpt-5-nano on Feb 09 2026)
