Abstract: Based on a research of the complex historical status and configurations in aircraft production, the basic features of single source of product data(SSPD) for aircraft production are presented. The information integration scheme is established by a master model and several sub models. By analyzing the principle of the logical relations between those models based upon the set theory, the constraints for the product integration model are summarized. Relational database models with these constraints are used in the proposed system. Change rules with full configuration and historical status are created for engineering changes. An SSPD prototype system is established to validate this modeling method. This system integrates the engineering data and manufacturing data which contain the effective transfer driven by configurations. This prototype system supports a paperless environment for assembly operation and inspection in the assembly workshop.
