Core Schema Mappings

Summary: Novel algorithms to compute core solutions for data-exchange mappings (tgds), bridging practice and core theory. Generates an executable script from a mapping scenario; implemented, tested on runtimes, achieving orders-of-magnitude faster core computation. (summarized by gpt-5-nano on Feb 09 2026)
