One-to-many entity-relationship diagram linking Painter and Painting tables through a foreign key relationship. The Painter entity stores painter_id (primary key), name, biography, and nationality; the Painting entity references painter_id as a foreign key alongside painting_id (primary key), title, year_created, and medium. This schema normalizes artist metadata from artwork records, eliminating redundancy and enforcing referential integrity. Fork and customize this diagram on Diagrams.so to adapt it for museum databases, gallery management systems, or art portfolio applications.
