The Public Petroleum Data Model (PPDM) is a non-proprietary data model that is designed for the oil industry to store, retrieve and process computer information more efficiently through standardization. By using a common model, data bases avoid duplicating information and improve the versatility of relating one item to any other item. It also allows compliant software to simply "plug in" to existing databases. With a common model, adding data or upgrading software becomes very easy and inexpensive. This will allow industry to better keep pace with new technology.
