A system of private data networks for sharing food ingredient information across production segments. Each network has shared communication between enterprise applications and one or more transactional event database for acquiring and storing event data for measurements, inputs, processing, transfers, and transformations of uniquely identified units of production. The data is stored at an atomic level with event data elements including an enterprise identifier, a unit of production identifier, a unit of production type description, an event type, and an event detail. The event data elements permit a tracking of the units of production through changes in ownership, changes in location, conversion of quantities of units of production, and changes in physical form. Additional event data elements may be provided for data security and auditing. Data marts are used to consolidate data related to particular business decisions.
