Abstract: To satisfy requirements of distributed product data management system in group-scaled enterprises, combining with Aerospace Vehicle Integrated Design Manufacture 3.0 (AVIDM ), a high-end Product Data Management (PDM) system was presented. It was aimed to manage heterogeneous, distributed product data in the group-scaled enterprises effectively, in which, a domain-based federated PDM framework and a PDM middleware platform were utilized to implement a multi-tier intra-domain architecture. The approach was able to support the loose and hierarchical organization structures amonggroup-scaled enterprises, and distributed down-to-top and top-to-down collaborative information exchange among domains. In different phases of the product lifecycle, the whole product database could be divided into a design library, a controlled library, a product library and a system library, wherein there was one-to-one correspondence between each product and an independent database. In addition, each library operated with an individual, distributed file server for high throughput. The rationale of the proposed, distributed solution of both data storage and application service was manifested using a practical high-end PDM application of complex products with long lifecycles.
