In multi-enterprises alliance for cooperatively designing and manufacturing product, all relevant data about the product is stored in the different product data management systems (PDMs) and databases respectively belonging to alliance members. In order to effectively integrating, storing and exchanging the decentralized product data among alliance partners, this article presents a distributed data storage model. This model comprises three levels: product data global mode (PDGM), product data segment mode (PDSM) and product data distribution assignment mode (PDAM). In PDGM, the global product information, such as product data dictionary and so forth, can be defined. PDSM can be used to obtain the compartmentalized product data segments with each having basic semantics and to define constraint conditions between product data. PDAM can help to store product data segments into dispersed enterprise database separately according to designated store mode and a certain redundancy, hence storing product data in a distributed, layered and cooperative style. Furthermore, this article put forward a correlative model of product information in multi-enterprises alliance environment, by which one partner can share product data segments from other partners and then assemble an integral product with its PDMs. Finally, all key enabling techniques have been practiced in an aviation project and the approaches proposed have been verified.
