Database Decomposition Into Fourth Normal Form
Summary: Algorithm decomposes a schema with functional and multivalued dependencies into Fourth Normal Form with lossless joins. It avoids closure computation and dependency-set restrictions; polynomial-time for broad classes beyond conflict-free sets. (summarized by gpt-5-nano on Feb 09 2026)
