Fast-food inventory management data dictionary defining seven core entities: Categoria, Producto, Proveedor, Inventario, Movimiento, Usuario, and Receta with primary and foreign key relationships. The schema enforces referential integrity through foreign keys linking products to categories, inventory records to products, stock movements to users and products, and recipes to ingredients via a recommended junction table. This normalized structure prevents data anomalies, ensures audit trails for inventory transactions, and supports role-based access control across Admin, Almacen, and Cocina user roles.
