Abstract: To effectively manage the product data during Web-based product development，the asp & XML-based product data manage environment is put forward.This environment consists of three parts： the product data management environment of each enterprise，the product data management environment in ASP platform，and the data integration environment among heterogeneous systems.The common data source based on variational single layer BOM can ensure uniqueness of product data efficiently，with better extensibility.The asp-based distributed product data management can satisfy the difference of the management modes among these enterprises.The XML-based data exchange mechanism can support adequately the data integration in heterogeneous systems.The case study proves that the environment is practical and effective.

Key words: Web-based product development, product data management, Application Service Provider（ASP）, eXtensible Markup Language（XML）

摘要： 为了满足网络化协同开发中复杂的产品数据管理需求，设计了基于ASP和XML的产品数据管理环境，该环境主要包括三个部分：（1）企业内部的数据管理环境；（2）ASP平台中的数据管理环境；（3）异构系统数据集成环境。基于单层变式BOM建立产业链级数据源，能够保证ASP平台中数据的统一性和良好的扩展性；基于ASP的分布式数据管理能够满足各企业管理方式的差异性要求；基于XML的数据交换机制能够充分支持异构系统的数据集成。最后介绍了该产品数据管理环境在摩托车产业的应用实例。
