Abstract: The present invention relates to an order data model for structuring data records in an order management system. The order model is configured to decompose each order into its corresponding item data records and sub-item data records, which in turn are associated with fulfilment item data records containing information on the product and/or services to be fulfilled by an assigned provider. The order model may be configured to add, during the generation of data record, a number of placeholder data fields, which may be used by a range of systems and applications to add extra information on each data record.
